The Megalethoscope during treatment in the lab.
The Megalethoscope is one of thousands of objects from The Henry Ford’s Collections Storage Building (CSB) that is being conserved, digitized, and rehoused thanks to a ‘Museums for America Collections Stewardship’ grant from the Institute of Museums and Library Services (IMLS), received in October 2017. Heading behind the scenes, this blog will explain the process that an artifact moves through from conservation to photography—and eventually, becoming viewable on Digital Collections.
Conservation Treatment
Once an artifact is selected, tagged, and inventoried, it is given a preliminary cleaning with a vacuum and transported into the Conservation Lab.

Prior to cleaning, a small spot was tested to determine the best method and materials to use. A mild detergent, diluted in distilled water did the best cleaning job without damaging the wood. The cleaning solution was gently rubbed on the wood surfaces with swabs to remove all of the dirt and grime, and then the surface was cleared with distilled water to remove soap residue. To bring back the shine of the wood finish, furniture wax was applied and buffed.
Years of storage on its end had caused the joints of the Megalethoscope’s viewer to separate (highlighted in red). Damaged areas were repaired removing the old, dried-up glue, and replacing it with fresh glue.
Large shrinkage cracks had developed in the two side panels that serve as light reflectors, and in the back panel that covers a large pane of glass. Shrinkage cracks develop when wood expands and contracts because temperature and humidity levels fluctuate too much.
Since the cracks were big enough to see through (approximately 1/8th inch wide) thin strips of Japanese tissue paper were soaked with a reversible adhesive, then dried, to fill each of the cracks. As each strip of tissue was compacted into the cracks, the adhesive was activated with solvent. This caused the dry paper to adhere to the edges of the crack and create a bridge. This fill was smoothed down flush with the rest of the wood panel, providing an even surface that could be in-painted to match the adjoining wood panels.
Using Japanese tissue to fill shrinkage cracks.
Watercolor and acrylic paints were used on the paper fills to hide the repairs and to paint in the large scratches and abrasions that covered the body of the Megalethoscope. To give the painted areas the same shine as the wood finish, a topcoat of acrylic gloss medium was applied.

To finish the treatment, the glass and mirror pieces of the Megalethoscope were cleaned with a solution of ethanol and distilled water, then wiped with microfiber cloths to prevent streaking. Any metal parts were cleaned with a mild solvent to remove small areas of corrosion and then waxed and buffed them to bring back their shine.

Investigating Megalethoscope Slides
During treatment, an original photographic slide left inside of the Megalethoscope was discovered. This led to additional investigation. The slide depicted is of the Ponte dei Sospiri in Venice (the Bridge of Sighs). We wondered if there were more of these slides in the collection and after checking our collections database, found a box labeled “Megalethoscope Slides” in the Benson Ford Research Center (BFRC). The contents of the box were not catalogued, so we decided we needed to go to the Archives to see for ourselves!
When the box was brought to the Reading Room at the BFRC, we opened the box and found 21 slides, all in good condition! Many of the slides were photographs of Italy and Paris, plus a handful depicting interiors.

Megalethoscope slides are large, multi-layered assemblies. Each slide consists of an albumen photographic image with pin pricks matching the areas where there is a light source or reflection (ex. an illuminated cityscape). Behind it are layers of colored tissue or cellophane and sometimes extra imagery when lit from behind; finally, there is a backing of a thinner, translucent canvas. All of this is stretched over a curved wooden frame. The curve creates a stereo view of the image which encompasses the viewer’s sight lines when they place their head into the Megalethoscope, much the way today’s virtual reality goggles work. Light is directed onto the slide to create different effects.

The slide that was found with the Megalethoscope in storage did not have any color effects, so we were excited to find that the majority of the slides in our archives had variations in color and optical illusions. The slides were moved to the conservation lab, where their surfaces were gently vacuumed. A smoke sponge removed any remaining dust and dirt. A few of the slides had small punctures or tears to the canvas, but since they were stable, we decided to not repair them at the present. We were thrilled to be able to reunite the slides with the Megalethoscope and have a fully functioning artifact!

Photographing the Megalethoscope

There are many steps that artifacts go through to be digitized and made available online, especially for objects as complex as the Megalethoscope. After the slides were conserved and cataloged, they were brought to the photography studio. For 3-D artifacts like the Megalethoscope, photography typically includes an image of the front, the back, and each side, if necessary. Photos serve as a reference material for historical researchers, and they document the condition of the artifact at that time.
The slides needed to be photographed in two ways: as they appeared in normal light, and as they would be seen through the Megalethoscope. Our senior photographer Rudy Ruzicska came up with a very clever arrangement to recreate this effect by placing two sets of milk crates with a sheet of Plexiglas suspended between them. He placed lights directly under and at an acute angle above the Plexiglas. The slides were placed in the middle of the Plexiglas with black paper border around the edges to prevent any light glare.

The Megalethoscope images were then photographed under normal (“daytime”) light to document their appearance, and with their “nighttime” illumination effect by turning off the studio lights. The first time we saw the images illuminated in the dark, we all gasped – they became so vibrant and magical!

The Megalethoscope was re-housed in a specially designed box which will store the unit and its base together safely, along with all of the slides. It was then moved to permanent storage in the Main Storage Building (MSB), as have most of the artifacts that we have worked on during the IMLS grant.
Thank you for joining me on this behind-the-scenes journey of an artifact from storage, to conservation, and through to digitization. I hope you enjoyed the ride!

This blog post is part of an ongoing series about storage relocation and improvements that we are able to undertake thanks to a grant from the Institute of Museum and Library Services (IMLS).
A typical aisle in the Collections Storage Building before object removal.
Autumn of this year marks the end of a three-year IMLS-funded grant project to conserve, house, relocate and create a fully digital catalogue record for over 2,500 objects from The Henry Ford’s industrial collections storage building. This is the third grant THF has received from IMLS to work on this project. As part of this IMLS blog series, we have shown some of the treatments, digitization processes and discoveries of interest over the course of the project. Now, we’d like to showcase the transformation happening in the Collections Storage Building (CSB).
A view of the aisle and southwest wall before dismantling to create a Clean Room.
Objects were removed from shelves allowing an area in the storage building to be used as a clean space for vacuuming and quickly assessing the condition of these objects before heading to the conservation lab. Since the start of the grant in October 2017, 3,604 objects have been pulled from CSB shelves along with approximately 1,000 electrical artifacts and 1,100 communications objects from the previous two grants. As of mid-March 2020, 3,491 of those objects came from one aisle of the building. As a result, we were finally at a point of taking down the pallet racking in this area.
Pallets of dismantled decking and beams. A bit of cleaning before racking removal.
While it has taken multiple years to move these objects from the shelves, it took only three days to disassemble the racking! Members of the IMLS team first removed the remaining orange decking. On average, there were four levels of decking, separated in three sections per level. Next, we unhinged the short steel beams that attach the decking to the racking. Then was the difficult part of Tetris-style detachment of the long steel beams directly by the wall from the end section of height-extended, green pallet racking. As you can see this pallet racking almost touches the ceiling! After that, the long beams could be completely removed before taking down the next bay. Nine bays were disassembled this time to reveal the concrete wall and ample floor space. Just as the objects needed cleaning to remove years of dust and dirt, so did the floor!
The aisle in 2018. An open wall and floor!
What’s next? We will methodically continue pulling objects and taking down racking until no shelf is left behind! We are grateful to the IMLS for their continued support of this project and will be back for future updates.

Before Greenfield Village: Henry Ford’s Early Preservation Projects
Greenfield Village’s historic buildings were not Henry Ford’s first preservation effort. Ford’s restoration of his own childhood home in 1919 set him on a preservation path. And it was just the beginning. Soon Ford began to restore other buildings.
In 1919, Henry Ford contemplated the importance of his own birthplace when a road improvement project required the farmhouse be either moved 200 yards from its original location or be torn down.

Ford decided to move the house and restore it to the way it looked at the time of his mother’s death in 1876, when he was 13 years old. For Ford, the project was personal--he took charge of the birthplace restoration, meticulously re-creating the details of the house.

After an 18th-month-long search, a Starlight stove like the one Ford remembered from childhood took its place in the restored Ford birthplace. THF255596
Ford worked hard to find original or similar furnishings. For 18 months, he searched for a Starlight stove like the one in the dining room when he was growing up. Ford’s staff contacted stove manufacturers and dealers and used the network of Ford Motor Company branch offices and automobile dealers to comb the country. When nothing turned up, his staff even placed advertisements in Detroit newspapers--though not revealing that it was Henry Ford who wanted the stove. After a nationwide search, Ford’s desire for a Starlight No. 25 was satisfied at last. He found one in a small Michigan town, paying $25 for it. Piece by piece, Henry Ford was re-creating his childhood home as he remembered it.

When the restoration of Ford’s childhood home was complete, people were awestruck by its authenticity. It seemed remarkable to him, and others, how a re-created environment could catapult one into another time and place.
Scotch Settlement School, Dearborn, Michigan, 1926. THF245410
In 1923, Ford bought and preserved the red brick Scotch Settlement School he had attended as a child. Henry Ford kept the building on its original site while he supervised every detail of its restoration.
Henry Ford’s restoration of his birthplace had received extensive press coverage. Not surprisingly, Americans deluged the wealthy man with pleas of assistance for preservation projects of their own. Although Ford turned down most requests for assistance, a few caught his fancy.
The Wayside Inn in the mid-1920s, after its restoration. THF132883
Henry and Clara Ford periodically visited the Wayside Inn, whose doors had been opened to the public. By 1927, however, Henry’s attention increasingly turned to his plans for his historical village and museum in Dearborn. THF 98987
Ford agreed to assist in the restoration of the 1686 Wayside Inn in Sudbury, Massachusetts, west of Boston. Henry Wadsworth Longfellow had made the inn famous in his Tales of a Wayside Inn. The author’s “Psalm of Life,” read by Ford in the McGuffey Readers of his youth, was among the industrialist’s favorite inspirational verses. Ford purchased the inn for $65,000, restoring and furnishing it at significant expense. He bought up much surrounding land and even diverted the Boston Post Road to keep automobile traffic from ruining the bucolic setting.
Presentation Drawing, "Proposed Development of a Colonial Village of South Sudbury, Massachusetts," 1926 THF58202
Ford clearly contemplated even grander plans for the Wayside Inn and its surrounding property. A “Proposed Development of a Colonial Village of South Sudbury, Massachusetts…done at the Lowthorpe School of Landscape Architecture” in 1926 shows a “village” composed of the Wayside Inn, houses, a church, a mill, and other buildings. Although the plan was never realized, Ford may have been working out ideas that were later revealed in Greenfield Village.

Closer to home, Ford refurbished the old Botsford Inn on Grand River Avenue in Farmington, Michigan, in 1924. The inn had once served 19th-century travelers en route from Detroit to Lansing. Ford’s staff sought out old-timers who remembered the inn in its heyday and used their recollections to help furnish the place. Ford added a maple floor to the ballroom and, for a while, held old-fashioned dances there.
Ford had turned down a request for funds to restore Williamsburg, the colonial-era Virginia capital. He was more interested in creating his own village closer to home, which would include buildings from different time periods and places. In 1927, Ford began to gather buildings for what would become Greenfield Village.

Two of Ford’s early preservation projects would find their way into Greenfield Village. During the summer of 1929, Scotch Settlement School was dismantled and moved as Ford’s historical village began to take shape. Ford’s birthplace would be the last building moved to the village during his lifetime. By the 1940s, the city of Dearborn was growing up around the Ford family homestead, and the house required 24-hour security protection. In January 1944, the home was cut in two and hauled by truck a few miles from the Dearborn farmstead to its new location in Greenfield Village.

The Budd Company approached American Motors Corporation in 1962 with this concept car, which placed a sporty body and a powerful V-8 on an inexpensive Rambler Ambassador chassis. Fearing it would fail, AMC decided against putting the car into production. Two years later, Ford's Mustang became a massive hit using the same idea of a sporty body on an existing chassis.

This blog post is part of a series about storage relocation and improvements that we are able to undertake thanks to a grant from the Institute of Museum and Library Services.
In the course of our work as conservators, we get some very exciting opportunities. Thanks to a partnership with Hitachi High Technologies, for the past few months the conservation lab here at The Henry Ford has had a Scanning Electron Microscope (SEM) with an energy-dispersive x-ray (EDX) spectroscopy attachment in our lab.
What does this mean? It means that not only have we been able to look at samples at huge magnifications, but we have had the ability to do elemental analysis of materials on-demand. Scanning electron microscopy uses a beam of electrons, rather than light as in optical microscopes, to investigate the surface of sample. A tungsten filament generates electrons, which are accelerated, condensed, and focused on the sample in a chamber under vacuum. There are three kinds of interactions between the beam and that sample that provide us with the information we are interested in. First, there are secondary electrons – the electron beam hits an electron in the sample, causing it to “bounce back” at the detector. These give us a 3D topographical map of the surface of the sample. Second, there are back-scattered electrons – the electron beam misses any electrons in the sample and is drawn towards a positively-charged nucleus instead. The electrons essentially orbit the nucleus, entering and then leaving the sample quickly. The heavier the nucleus, the higher that element is on the periodic table, the more electrons will be attracted to it. From this, we get a qualitative elemental map of the surface, with heavier elements appearing brighter, and lighter elements appearing darker. 
Conservation Specialist Ellen Seidell demonstrates the SEM with Henry Ford Museum of American Innovation volunteer Pete Caldwell.
The EDX attachment to the SEM allows us to go one step further, to a third source of information. When the secondary electrons leave the sample, they leave a hole in the element’s valence shell that must be filled. An electron from a higher valence shell falls to fill it, releasing a characteristic x-ray as it does so – the detector then uses these to create a quantitative elemental map of the surface.

The understanding of materials is fundamental to conservation. Before we begin working on any treatment, we use our knowledge, experience, and analytical tools such as microscopy or chemical tests to make determinations about what artifacts are made of, and from there decide on the best methods of treatment. Sometimes, materials such as metal can be difficult to positively identify, especially when they are degrading, and that is where the SEM-EDX shines. Take for example the stamp-block letter shown here. The letter was only about a quarter inch tall, and from visual inspection, it was difficult to tell if the block was made of lead (with minor corrosion) or from heavily-degraded rubber. By putting this into the SEM, it was possible a good image of the surface and also to run an elemental analysis that confirmed that it was made of lead. Knowing this, it was coated to prevent future corrosion and to make it safe to handle.
Elemental analysis is also useful when it comes to traces of chemicals left on artifacts. We recently came across a number of early pesticide applicators, which if unused would be harmless. However, early pesticides frequently contained arsenic, so our immediate concern was that they were contaminated. We were able to take a sample of surface dirt from one of the applicators and analyze it in the SEM.
An SEM image of a dirt sample from an artifact (left) and a map of arsenic within that sample (right).
The image on the left is the SEM image of the dirt particles, and the image on the right is the EDX map of the locations of arsenic within the sample. Now that we know they are contaminated, we can treat them in a way that protects us as well as making the objects safe for future handling.
We have also used the SEM-EDX to analyze corrosion products, to look at metal structures, and even to analyze some of the products that we use to clean and repair artifacts. It has been a great experience for us, and we’re very thankful to Hitachi for the opportunity and to the IMLS as always for their continued support.

Have you ever wondered how we photograph quilts at The Henry Ford? While the answer is probably no, you might be surprised to find out that it is quite a process. Most quilts are quite large, ranging from 7ft x 4ft to even 9ft x 5ft. With that being said, our photo studio in the museum only has a ceiling that is 10ft tall, but to get an accurate picture of the quilt we would need the camera to be pointing at the quilt at a 90-degree angle. How do we accomplish that in a room that’s only 10 ft tall? We find higher ground!
Since our studio is on the back wall of the museum, we need to be somewhere elevated, but relatively nearby so we aren’t hauling our equipment all over the place. So, the Highland Park Engine is our answer. We mount the camera on the top railing of the stairs closest to the entrance to Conservation.
Then, with the help of 2-3 people, we lay the quilts on a large 10 x 10 wooden board that has a layer of muslin cloth on it (to protect the quilts and stop them from sliding down the board), We hoist the quilt board up onto stands to hold it in place at about a 60-degree angle which allows us to angle the camera to shoot straight at the quilt, giving us the correct perspective as if it were lying flat.
Here are a few examples of the finished images that go online on our Digital Collections website.
Looking at them, you wouldn’t think that they were photographed any other way than lying down, right? That’s the magic of photography - with a little bit of resourcefulness and ingenuity added in.
You can view all the quilts from our collection that we’ve photographed on our Digital Collections here.

The Logan County Courthouse, a fixture on the Village Green in Greenfield Village, will has reached the milestone of having been here in Dearborn for as many years as it was in Postville, Illinois - 89 years.
Abraham Lincoln featured prominently in Henry Ford’s plans for Greenfield Village, which revolved around the story of how everyday people with humble beginnings would go on to play important roles in American history. Lincoln epitomized Ford’s view of the “self-made man,” and he made a significant effort to collect as many objects as possible associated with him. By the late 1920s, Henry Ford was a “later comer” to the Lincoln collecting world, but with significant resources at his disposal, he did manage to secure a few very important items. The Logan County Courthouse is among them.
It has taken nearly all the 89 years to achieve this, but an original feature, long absent from the courtroom is making a return. The bar now stands again. Using the original set of spindles, we have re-created our interpretation of what the rail, or the bar, that divided the courtroom may have looked like in the1840s. By referencing images of other early 19th century courtrooms, and studying architectural features represented in Greenfield Village, a typical design was created.
The stories associated with the Logan County Courthouse are fascinating. As it turns out, the story of how the original spindles from the original bar finally made their way back into the courthouse is fascinating as well.
Authenticated objects, related to Lincoln’s early life, were especially scarce by the late 1920s. There seemed to be an abundance of items supposedly associated and attributed to Lincoln, especially split rails and things made from them, but very few of these were the real thing. For Ford, the idea of acquiring an actual building directly tied to Lincoln seemed unlikely.
But, by the summer of 1929, through a local connection, Ford was made aware that the old 1840 Postville/Logan County, Illinois courthouse, where Lincoln practiced law, was available for sale. The 89-year-old building was used as a rented private dwelling, and was in very run-down condition, described by some as “derelict.” It was owned by the elderly Judge Timothy Beach and his wife. They were fully aware of the building’s storied history, and had made several unsuccessful attempts to turn the historic building over to Logan County in return for taking over the care of the building. Seeing no other options, the Beaches agreed to the sale of the building to Ford via one of his agents. They initially seemed unaware of Ford’s intentions to move the building to Greenfield Village, assuming it was to be restored on-site much like another historic properties Ford had taken over.
This image shows the state of the building when it was first seen by Henry Ford’s staff in late August of 1929. Not visible in the large shed attached to the rear of the building. THF238386
The local newspaper, The Courier, even quoted Mrs. Beach as stating that, “she would refund to Mr. Ford if it was his plan to take the building away from Lincoln, as nothing was said by the agent about removal”. By late August of 1929, the entire project in West Lincoln, Illinois, had captured the national spotlight and the old courthouse suddenly had garnered a huge amount of attention, even becoming a tourist destination. By early September, local resistance to its removal was growing, and Ford felt the need to pay a visit to personally inspect the building and meet with local officials, and the Beaches. He clearly made his case with the owners and finalized the deal. As reported, “Ford sympathized with the sentiment of the community but thought that the citizens should look at the matter from a broader viewpoint. He spoke for the cooperation of the community with him in making a perpetual memorial for the town at Dearborn, where the world would witness it. My only desire is to square my own conscience with what I think will be for the greatest good to the greatest number of people."
Henry had made his case and the courthouse would indeed be leaving West Lincoln. Immediately following the final negotiations, Henry Ford’s crew arrived to begin the process of study, dismantling, and packing for the trip to Dearborn. Local resistance to the move continued as the final paperwork was filed to purchase the land. By September 11, the resistance had run its course and the dismantling process began. It was also revealed that the city, county, several local organizations, and even the state of Illinois had all been offered several opportunities to acquire the building and take actions to preserve it. They all had declined the various offers over the years. It was then understood that Judge & Mrs. Beach, in the end, had acted on what was best for the historic building and should not be “subjected to criticism.” Judge Beach would die on September 19, just as the last bits of the old courthouse were being loaded for their journey to Greenfield Village.
Reconstruction, which included the fabrication of many of the first-floor details and a new stone chimney and fireplaces, began immediately. In roughly a month’s time, the building was ready for the grand opening of Greenfield Village on October 21, 1929.
Nine years later, in 1938, Eugene Amberg sent a letter to Ford describing an interesting discovery. Mr. Amberg was a native of what was now Lincoln, Illinois and worked as a railroad ticket agent. He had a great interest in the local history and was a collector of local artifacts. As he writes in the letter dated February 8, 1938:
Several years ago, you purchased the Old Postville Court House here in Lincoln, Ills from Mrs. T Beach. At the time the Court House was made into a dwelling the railing that separated the judges desk from the main court room was torn out by my father (John Amberg) who was doing the remodeling, this he stored in the attic of his home, recently my mother died and while cleaning out the attic we came across these spindles, which are the original 28 spindles that the hand railing rested upon. The hand railing was of walnut, out of which was carved some arm rests that are now on some of the pews in St. Mary’s, a church here.
Would appreciate a line from you as to whether or not you would be interested in these spindles, have had numerous offers for them, inasmuch as they are part of the original court house I feel they should be with it, in your Dearborn Village.
Dated February 7, 1938, this is the initial letter from Gene Amberg to Henry Ford offering the 28 original spindles for sale. Despite several letters back and forth, a price could not be settled upon, and the transaction never took place. THF288006
This drawing was sent by Gene Amberg, as a follow-up to his first letter offering the spindles for sale. The artist, Mary Katherine, was Gene’s 14 year old daughter. THF288012
Negotiations evidently faltered, as a price was not agreed upon, and the spindles were never sent. Fast forward 71 years to 2009 when an email arrived from Carol Moore and her brother, Dennis Cunningham, the grandchildren of Eugene Amberg. They had no idea that their grandfather had begun this process, and were amazed when we produced the original correspondence from our archival collection. As it turns out, their story was almost identical to Eugene’s. As Carol wrote their mother, “Patricia Amberg Cunningham died March 1, 2008. While cleaning her house in Delavan, Illinois to prepare for sale, we found 28 old wooden spindles and a newspaper article believed to be from the Lincoln Courier indicating that the spindles are from the original Postville Courthouse in Lincoln, Illinois. It is our desire to donate them to the original Postville Courthouse.”
She was very familiar with Greenfield Village, and had visited the courthouse here. Jim McCabe, the Buildings Curator at the time, gladly accepted the donation.

In 1848, the county seat moved from Postville, to Mount Pulaski. At that time the courthouse was decommissioned, and the county offices moved to a new courthouse. After a legal battle between the County, and the original investor/builders of the building, it was sold to Solomon Kahn. None other than Abraham Lincoln successfully represented the County in the matter.
Understanding the local history helps to also understand the changes that took place to the building. It explains how and why portions of the building were altered, parts removed, and eventually separated.
By the late 1840s, changes had taken place on both the exterior and interior. The most significant of these was the move off its original foundation, 86 feet forward on the lot. Mr. Kahn converted the building into a general store, and ran the local post office. It was he who moved the building to its new location. In doing so, it was lifted off its original limestone foundation, and the original single limestone chimney and interior fireplaces were demolished. A new brick lined cellar and foundation were created, along with updated internal brick chimneys on each end of the building, designed to accommodate cast-iron heating stoves.
This is the earliest known photograph of the Logan County Courthouse taken some time between 1850 and 1880. This photograph shows the building in its second location, 80 feet forward from its original foundation, at the crest of a small rise. The original window and door configuration remain intact. The original single stone chimney, now restored to the left side of the building, has been replaced by two internal brick chimneys designed for cast-iron heating stoves. Though not visible in the photograph, the building now sits on a new brick foundation and cellar. The items sitting near the doorway speak to the building’s new life as a store. THF132074
By 1880, the old courthouse had been converted from a commercial building into a private dwelling, and that was the state in which it was found by Ford’s crew in 1929. The doorway and first floor interior had been radically changed. Later, a porch was added to the front entrance, and a shed addition was added to the rear. Photographs taken in September of 1929 during the dismantling, show the outline of the original chimney on the side of the building where it has been re-created today. Further discoveries revealed the original floor plan of a large single room on the first-floor, and the original framing for the room divisions on the second. Second floor photographs show the original wall studs, baseboards, chair rails, window, and door frames, all directly attached to the framing, with lath and plaster added after the fact. The framing of the walls on the first floor were all clearly added after the original build.
This post 1880 view of the Logan County Courthouse shows its transformation into a two- family dwelling. Note the single doorway is now two, the second now taking the place of a former window opening. THF238350 
This image shows further remodeling of the front of the building. This photo ca.1900 shows the addition of recessed covered porch with some decorative posts and millwork. This is the iteration in which the building was found when it was sold to Henry Ford in September of 1929. THF238348
These three images show the re-modeled interior of what was the original courtroom, now serving as the kitchen, dining room, and parlor. These photos were taken by Henry Ford’s staff just prior to the dismantling of the building in September of 1929. THF238580

We have no evidence that tells us what if any interior changes Mr. Kahn may have made when he relocated the building around 1850. The earliest photograph we have of the building shows it in its new location, but except for its new brick chimneys, it retains what appears to be its original door and window configuration. We can only assume that Mr. Kahn had kept the rail in place, which may have proved useful in the building’s new configuration as a store and post office. No photographs of the original courtroom exist and extensive changes made first in 1880, and then when the building was dismantled and reconstructed in Greenfield Village, further comprised any original evidence.
This view of the dismantled second floor shows matching trim and chair rail connected directly to the studs indicating this as the originally installed woodwork from 1840. The wall partition studs are also notched to meet the ceiling joists, showing that they are also part of the original framing configuration of the second floor. All the trim work, including the doors were made of walnut. THF285571
Based on the evidence we do have about these changes, it is very likely that at the time of the building’s conversion into a private dwelling, around 1880, the decorative hand-turned spindles and walnut hand rail would have been salvaged as the first floor of the building was sub-divided into a duplex. As stated in the family history, the walnut top rail was re-purposed and used in St. Mary’s Catholic Church (which burned in 1976), and the spindles saved for a future project.
Analysis of the original spindles showed that they were poplar, a wood commonly used for turning and as a secondary wood in the mid-19th century. Based on what we knew, we decided to use a combination of woods for the reconstruction of the bar rail. Walnut was used for the top rail and column caps, and the remainder of was done in poplar. Though refinished in 1929, the original walnut trim throughout the building was used as a guide for the color and sheen of the final finish. Reproduction hardware, again based on the existing hardware, mainly on the second floor, was used to mount the center gate.

The design of the physical installation of the rail and gate was robust. Each of the support columns is supported within by a steel post that runs through the floor joists and into the cellar floor. With over a half million guests visiting Greenfield Village each year, we thought this important. The design also offers some degree of protection to the original spindles that are centered within the top and bottom rail. This is a permanent installation, and we wanted to be sure it would stand up to the test of time.

A huge thank you to Mary Fahey and Dennis Morrison for stewarding the project. Also to Mose Nowland, our extraordinary volunteer with The Henry Ford’s Conservation Team, who lead the charge in creating the design, and produced beautifully detailed drawings. Ken Gesek, one of our Historic Buildings Carpenters, built the rail, Cuong Nguyen and Tamsen Brown, with the help of the rest of the THF Conservation Team, oversaw the restoration of the original spindles. Tamsen also developed the formula to match the stain and finish to the existing woodwork in the courthouse. Jason Cagle, from the Painting Staff, skillfully applied the finish. Many other people worked to move the project forward as well.
This true team effort resulted in the original spindles finally being reunited with the Logan County Courthouse after an absence of nearly 140 years.

In October 2017, Henry Ford Museum of American Innovation was awarded another Institute of Museum and Library Services (IMLS) grant, allowing us to continue working to catalog, conserve, package, and rehouse over 3,000 items out of our Collections Storage Building. We've had the opportunity to work with some very interesting objects for this grant, from agricultural equipment to advertisement signs. There is a wide array of objects passing through the labs, visible to the public through the windows at the back of the museum.
This spring we treated many batteries made by Thomas Edison. Most of these originated from the late 19th century and varied in condition and composition. These early battery types consist of metal plates that were immersed in an electrolyte solution to generate electricity. The batteries themselves were stable and safe to handle because they contained no electrolyte. The batteries with unknown compositions sparked our curiosity (pun intended), since we needed to know what they were made of so that we could properly conserve them.
Sometimes while working in the lab, we need specialized equipment that we may not have on site. Fortunately, museums often work collaboratively to help each other find solutions. In this case, we collaborated with Conservation Scientist Christina Bisulca and the well-equipped analytical conservation lab at the Detroit Institute of Arts. The DIA had the right tool for the job - a high-powered optical microscope and X-ray fluorescence (XRF) spectrometer. An XRF spectrometer is essential to conservators because it is used to identify metals. It uses an X-ray beam to produce enough energy to excite electrons within the atoms of metal elements. When that energy is released, a specific signal is registered within the XRF spectrometer and the metal is identified.

At the beginning of March, we brought several batteries to test at the DIA, including an Edison-Lalande battery, a Samson battery, and an Edison S-Type battery. The Edison S-type battery was particularly interesting, since we were not able to find any similar batteries to compare it to, and could not confirm the materials used through research alone.

In this blog post, conservator Louise Stewart Beck shared some incredible photographs of corrosion products that seemed to grow from the metal itself. We have found a lot of corrosion products where metal and hard rubber materials meet. In this collection, it happens frequently, and it makes sense to find these two materials so often due to the physical properties of the materials and their uses in regards to electricity.
Let’s start with the metal. Metals are strong materials, allowing the objects to withstand the working environments where they were used. Additionally, metals make great conductors, allowing the electricity to readily flow through the desired path along wires.
While metals are conductors, rubber is an insulator. This means it restricts the flow of electrons and prevents the electricity from transferring to separate entity—like a person—accidentally.
With this in mind, it makes sense that both metals and hard rubber would be found next to each other for the electrical objects to perform their function when first created. The long-term proximity of metal and hard rubber on these objects, unfortunately, also leads to active deterioration of the object. This situation is called inherent vice: The deterioration of physical objects due to the instability of the materials that make up the object.

Detail of hard rubber corrosion on surface of the metal. (Accession number 31.1217.252).
When Louise and I encounter the strange corrosion products where hard rubber and metal touch, we end up removing the product of a chemical reaction occurring due to the physical properties of the two materials. If the corrosion product is only removed, it will be back in a few years because the chemical reaction has not been stopped by simply removing the corrosion. Whenever possible, a barrier is placed between the hard rubber and metal to keep them from chemically interacting with one another. Our barrier of choice is Incralac, a clear non-reactive coating. When possible, we apply the coating to the metal after separating it from the hard rubber and allow it to dry. Once dry and reassembled, the barrier layer should prevent the chemical reaction that results in the interesting corrosion growth.

Of course, a lot of thought goes in to each treatment for each unique object, making working with this collection both challenging and rewarding. Understanding the ways objects are originally created that may cause or increase deterioration allows us in the Conservation Lab to actively work to slow this deterioration down to ensure the object can be enjoyed by visitors for years to come.

As we start a new year, it’s a good time to look back on the first half of The Henry Ford’s IMLS-funded grant to work on electrical objects, and to take stock for the future.
We had a busy and productive fall 2016, with some new adventures thrown in with continuing progress on objects themselves. If you haven’t already seen them, you should check out our Facebook Live videos – we’ve done a few so far (in October, November, and December), and the plan is to continue doing them on the first Friday of each month.
Gaulard & Gibbs transformer on the shelf before treatment (29.1333.229).
This Gaulard & Gibbs transformer had several conservation issues when we first saw it, most notably that the wooden base had broken under the strain of the weight of the object itself. You can see this in the before picture, where the object is lying on its side because it cannot stand anymore. There are also faint hints of color along the metal tabs that run up the body of the object.
The Gaulard and Gibbs transformer after treatment (29.1333.229).
You can see that this transformer had a fantastic transformation during conservation treatment – simply removing years of built-up dust revealed a very vivid red and black coloration. The broken wooden base was also very successfully repaired, and it is now possible for the object to stand on its feet again. When it’s packed for storage, it will be lying down again, so that the weakened wooden base isn’t put under too much strain for long periods of time.
We featured this object briefly in our Facebook Live videos – you may have noticed, if you tuned into both, that you could see the ‘before’ and ‘after’ as they happened.

We’ve also encountered some interesting materials and material problems in the first half of our IMLS grant work. One of the most interesting was this strange accretion, found on the interior of a meter. Those brownish bulbs appeared to be seeping into the object from the top, but were only present on the enameled portions of the metal. They were friable and lighter on the inside than the outside. We looked at samples under the microscope, and even attempted to culture a sample, in case it’s a type of mold (it does not appear to be). We’re still not sure what exactly they are, but we will continue to try to figure it out! Mysteries of the museum, indeed.

We have also recently come across a fantastic example of perfectly preserved hard rubber. The base of the object is one solid slab of hard rubber, but the protected interior area has retained the original black, mirror-like finish. The discoloration and matte surface of hard rubber occurs primarily from light exposure over time, and the colors possible range from a light black to the red-brown color on this object. We’ve put the exterior cylindrical case back on the object, sealing it well, so that the very tight case can continue to preserve this fantastic interior. 
Conservator Cuong Nguyen and Conservation Technician Andrew Ganem working on motors in their lab.
We have also been very fortunate to have Cuong and Andrew working with us for a little while. They're tackling some larger motors, which take longer to complete. Their help allows Conservation Specialist Mallory Bower and I to continue to work at the pace necessary to keep the project on target, while ensuring that as much of the collection as possible is treated. We greatly appreciate their help.
As always, this is only a small sampling of what we have been up to on the IMLS project. Please feel free to stop by our window at the back of the museum and see what we’re working on – there is always something interesting on our desks. Keep your eyes peeled for our next Facebook Live, as well. As we continue to move into 2017 and are fully into the second half of the project, we are excited to continue our work and continue keeping you updated
