The Henry Ford holds an extensive collection of late 19th century political campaign lanterns, dating from the 1860 to 1900. These paper, accordion-folded lanterns usually held candles and were used in processions and rallies in support of the candidates. They are screen printed in patriotic colors - some contain images of the candidates and/or slogans. In an age before television and radio, processions were a method of attracting attention for a political race. As paper objects these are truly ephemeral objects. Their survival for more than 100 years is remarkable. Continue Reading
You might have heard that we are partnering with Litton Entertainment to create a brand-new TV show, The Henry Ford’s Innovation Nation, premiering on CBS later this year. As we worked with Litton to develop story ideas that might be featured on the show, we also wanted to make sure we digitized a variety of artifacts from our collections related to those stories. To that end, we’ve just digitized a couple dozen photos of the Rosa Parks Bus before and during its 2002 restoration. As former curator Bill Pretzer relates online, the bus had been left in a field and used as a storehouse for decades, leading to the significant condition issues that you can see in this photo of the driver’s seat. See more newly digitized photos of the restoration process by visiting our collections website, and learn more on Innovation Nation this fall!

The Henry Ford, like other older, long-established museums, can only display a very small percentage of its artifacts at any given time. The remainder is kept in storage for future generations. In recent years, The Henry Ford has begun to digitize its collections, and put them online. This effort has helped expand what we can say about what is on exhibit, and importantly, has made it so that people don’t have to wait decades to be able to find out about artifacts that are in storage.
Thanks to a grant from the Institute for Museum and Library Services’ (IMLS) “Museums for America” program, The Henry Ford has an opportunity to digitize over 1,000 artifacts that tell the story of changing communications technologies from the late 1800s to the late 1990s. The project is focused on communications collections that are stored in a large, tightly-packed warehouse on The Henry Ford campus. Many of these artifacts have been in this building for many decades, with limited cataloging. This project will inventory, catalog, preserve, re-house and digitize for online access these computers, radios, telephones and televisions, cameras, printing presses, teletype and telegraph machines and other artifacts, making them available to The Henry Ford staff and the public to a degree never before possible.
Our computer collections have been the focus of the early work. This work has reminded us of how rapidly technological change has occurred with computers. Check out the (not so mini) DEC PDP-11/20 Minicomputer, 1970 mini-computer.
The challenges presented by this densely-packed storage area has meant that the project staff has really needed to live up to our mission of innovation. Before any work can be done on the artifacts, decades of accumulated dust, dirt and mold needs to be removed. Collections Specialist (and in-house McGyver) Jake Hildebrandt fashioned a downdraft table, complete with HEPA and charcoal filter, out of a portable ventilator, steel shelves and leftover grid for overhead lights. A downdraft table quickly pulls away dust and dirt as the artifact is cleaned, making the cleaning process faster and more effective.
We look forward to highlighting some of our exciting “re-discoveries” as we work on this project; collections digitization projects in museums around the world have led to new “re-discoveries.” We expect to add the tremendous collections of The Henry Ford to this ever-expanding resource of artifacts online.

In the 1860s and 1870s, supporters of certain political figures used pleated paper lanterns, lit with candles, during rallies and parades to demonstrate their enthusiasm for their candidate. As one might expect, the delicate paper was often destroyed—or accidentally set ablaze. The Henry Ford has just finished conservation and digitization of a dozen political lanterns from our collections, including this one indicating support for James Garfield and Chester A. Arthur. View all of the restored political lanterns in our digital collections.

In early February, the Conservation Department did its yearly inspection of the Dymaxion House with the assistance of Historic Operating Machinery Specialist Tim Brewer. As you’ll recall, it is truly a “tension” structure; the “cage” actually hangs the house off of the central mast. Every year we compare measurements of the cage rings to see what might be out of alignment. We also measure the tension on critical cables and adjust them as necessary.
I am pleased to report that our repairs from two years ago are holding up well. We learned from our engineering study last year that the expected longevity of the repaired beams is excellent. We continue to monitor for any new cracks both visually and with permanently installed wire gauges.
Things went so well with the regular inspection that we were able to make a few improvements.
We installed our prototype version of the “neoprene gutter”. This is the sheet-rubber trough located above the windows inside the house. It was supposed to collect water that would trickle down from the u-shaped “carlins” supporting the roof and carry it to a tank under the house via the black downspout near the back kitchen door.
During our original restoration of the house back in 2000, we decided not to attempt the gutter. Although we found various design plans by Buckminster Fuller’s engineers, we had no proof that they were successful. It was probably one of the “unfinished details” that Bucky was doggedly trying to solve and that eventually helped to scuttle the Dymaxion Dwelling Machine company back in 1946. Yet without that internal gutter, the rain-collection function of the carlins (the U-shaped roof supports) was difficult to interpret. We're happy with our new mock-up gutter.
The new light-color-changing switch located under the “ovolving shelves” is working well, too. The color of the light can be changed. This was a feature that Buckminster Fuller wrote about while he was designing the house.

At The Henry Ford, Conservation’s job is to maintain artifacts as close to original condition as possible while also ensuring access. The Dymaxion House is a fairly fragile aluminum structure, and a very popular exhibit, which makes preservation a little bit of a challenge.
Last year we did some rather major surgery on the Dymaxion House. We opened up the floor and patched all 96 aluminum floor beams to reinforce them where many had developed cracks.
As I explained in past blog posts, linked below, the damages were found primarily on the heavy-traffic side of the house, where our guests walk through. The repair job in 2012 took two months of hard work.
After all that effort, how do we ensure that this kind of damage won’t progress?
This year we are setting up some cool monitoring devices that will help us understand the house better.
All metal structures move. We want to figure out how our beams are moving, and whether the structure can continue to withstand the forces we apply to it.
Under the guidance of our own engineer, Richard Jeryan, who is retired from Ford Motor Company, and with the generous assistance of Ford Senior Chassis Test Engineer Dave Friske and two skilled technicians, Instrumentation Expert Walter Milewsky and Fastener Lab Technician Richard Talbott, we are installing stress and strain gauges along with crack detection and propagation gauges.
These gauges are the kind of very precise instrument used by engineers to find out how structures perform. They are used to test automobile parts (even ones as small as bolts) during design, and are also used on buildings and bridges.
Strain gauges are used to measure the amount of deformation (strain) when a building is loaded. Put another way, stress is a measurement of the load on a material, strain is a measure of the change in the shape of the object that is undergoing stress. We will be recording a baseline stress on the beams with the house empty of people and collecting our strain data on a busy week in the museum (like the Fouth of July!).
The crack detection gauges will alert us to a crack that is starting, and the propagation gauges will tell us how quickly a new crack is progressing.
These tiny devices are glued onto the beams and wires soldered onto them so that electrical resistance can be monitored with special equipment. Engineers gather the electrical resistance data and use formulas to calculate the degree and character of stress. We are applying the gauges in a number of locations to gather the best overall picture of how the beams move.
We also measured the deflection of the structural wire “cage” using a fancy laser-level and we recorded the data. This will enable us to compare yearly readings during our annual inspection to determine how the cage may be moving.
This is science and technology – working for preservation.

In the past few years, the Conservation Department has worked on a number of historically important flags from Michigan, including several Civil War battle flags.
This flag dates from the end of the 19th century and was used by a G.A.R. post in Lyons, Michigan. The G.A.R. (Grand Army of the Republic) was a Union veterans’ organization formed after the Civil War and there were posts in almost every town in Michigan. This flag would have been used in parades on patriotic occasions in Lyons. In 1917 the flag was donated to the town “to raise at funerals of G.A.R. or veterans of any war.” It was displayed for many years in the Lyons-Muir Historical Museum. Its caretakers recognized the need to preserve it and brought it to Textile Conservator Fran Faile.
Over the course of several months, the flag was humidified and flattened to reduce distortions in the weave. It was stabilized and protected by encasing it between layers of sheer nylon tulle. Hand stitching secures all the small fragments of fabric from moving or being lost. The Historical Society is presently having a protective case built that will enable the flag to rest flat rather than be stressed by continued hanging.
Years of use and display had made the silk fabric very fragile.
The painted lettering was especially brittle.
All the fragments were flattened and arranged between the layers of tulle.
The paint was humidified and flattened.
Ready to be installed in its new case!

Conservators at the Henry Ford Museum are collaborating with violin experts to prepare Henry Ford’s personal violin collection for an upcoming permanent display in Henry Ford Museum. The violins, which have been in storage for a number of years, are being examined, analyzed and in some instances conserved for long-term display and potential use in concerts.
As a violin enthusiast, Henry Ford purchased some of the finest instruments including violins made by Antonio Stradivari (1644-1737), Bartolomeo Giuseppe Antonio Guarneri (1698-1744) and Carlo Bergonzi (1683-1747).
In 2010 master violin restorer Ashot Vartanian of Shar Music in Ann Arbor, Mich., repaired the Bergonzi to prepare it for exhibition and a concert in Cremona, Italy.
Later this year Henry Ford’s 1703 Stradivarius violin will travel to Cremona to replace the Bergonzi, which will return to The Henry Ford for examination and analysis. Sharon Que of Sharon Que Violin Restoration and Repair is currently working with Chief Conservator Mary Fahey to evaluate the condition of the violin and to make necessary repairs. The retention of original varnish and wood as well as the preservation of the extraordinary sound of the violin is paramount.
Radiologist Dr. John Bonnett of Henry Ford Hospital and luthier Ray Schryer (Schryer Violin) partnered with Henry Ford Museum staff in 2010 to create CT scan (computed tomography) images of the violins in a quest for information concerning their condition and past repairs. Among other findings the scans revealed areas of old insect damage, previously unseen by the naked eye, in addition to delicate repairs on the interior of the museum’s Guarneri Del Gesu violin.

Conservators at The Henry Ford have begun to work on the second group of figurines belonging to Polish Mission in Orchard Lake, Mich.
The figurines, which are part of a Panorama created by architect Zbigniew Baran, have educated and entertained audiences, both young and old, for more than 30 years. It’s the only historical Polish Panorama in North America. The 106 characters of the panorama, which dramatizes the history of Poland, are drawn from the struggles of writers, peasants, saints, statesman, soldiers, and artists to remain faithful to the ideals of Christianity and the Polish nation.
Baran, together with THF Head Conservator Mary Fahey and her staff, are working to clean, conserve and restore missing elements of the figures in addition to developing a plan for their long-term care and preservation.
Missing elements such as the sword and crucifix for the Mieszkol I (the first king of Poland) figurine were fabricated using historical images as references. Check out the images (below) of the figurine before and after conservation.
To see the panorama in action, take a look at this video from WDIV Detroit in 2011. To learn more about the efforts to continue the conservation work of the figures, take a look at this site.
