Pictorial Record of the United States Army Air Forces 90th Bombardment Group, ca. 1942-1945

2 volumes containing approximately 412 photographs and 1 manuscript item

The Pictorial Record of the United States Army Air Forces 90th Bombardment Group consists of two volumes containing 1 manuscript item and approximately 412 photographs documenting the activities of the USAAF 90th Bombardment Group during the New Guinea campaign of War World II.

Materials are housed in plastic sleeves contained in two green-colored 3-ring binders (30 x 33 cm). All photographs are gelatin silver developing-out prints and for the most part measure between 10 x 12 cm and 26 x 20 cm in size. Numerous images bear stamps that state “Passed by U.S. Army Examiners.” Most images do not have captions, though a small number do have typescript captions on their versos.

Volume A:

Volume A contains approximately 186 photographs as well as 1 manuscript item. The volume begins with a one-page typescript document issued ca. 1944 that is addressed to the 400th Bomb Squadron 90th Bomb Group, stating the photographs are intended to be “the Pictorial Record of Our Unit.” The letter is signed by Maj. C. Vernon Ekstrand of the U.S. Army Air Corps. Photographs include a composite portrait of the 90th Bomb Group members, individual and group portraits of 90th Bomb Group members, a group portrait of Japanese military personnel, images of Allied military facilities, Japanese warships being bombed, military aircraft shown both midair as well as on the ground, what appears to be an abandoned Japanese tank, and numerous landscape views. Also present are several images showing aircraft nose art. Of particular interest are various pictures documenting interactions with native Papuan people including individual and group portraits as well as photographs of Papuan settlements and structures (including churches).

Volume B:

Volume B contains approximately 226 photographs. This volume includes a substantial number of pictures of indigenous Papuan individuals, children, and families, including several portraits of nude women (including mothers breastfeeding), as well as images showing traditional Papuan body modifications and tattoos. Of particular note are images that appear to document a Papuan ceremony that showcases elements of traditional Papuan clothing, music, and ritual dance, as well as a photograph of a Papuan trumpet player. Other items of interest include numerous images documenting USO performers (including Bob Hope and Patty Thomas) and a series of aircraft nose art photographs that include several works signed by Cpl. Al G. Merkling. Images of airborne planes and landscape views also feature prominently in this volume.

Wilbur Wright Airfield Photograph Album, ca. 1917-1918

250 photographs in 1 album

The Wilbur Wright Airfield photograph album contains 250 images taken by Corporal J. O. McDonnell that mainly document military activities at Wilbur Wright Airfield in Ohio during World War I.

The album (18 x 28.5 cm) is string-bound and has black leather covers with "Photographs" stamped in gold on the front and black paper pages. Images are sequentially numbered in white pencil. Contents primarily cover a range of aviation training activities and other operational aspects of Wilbur Wright Airfield. Various training aircraft are documented in detail; the majority were Curtiss JN-4s, known as “Jennys,” but the base also had some DeHaviland DH-4s. Numerous views of planes are included, showing them on the ground, in the air, and operating in all seasonal conditions. Several crash landings are also documented, with most of the wrecks appearing to be “nose-overs” (planes flipping forward upon landing) rather than high-speed crashes into the ground.

In addition to pilot training, Cpl. McDonnell also documented aspects of daily life at the base including hangars, mechanics shops, fabrication areas, and barracks. Photographs include shots of military personnel working on planes, lounging in barracks, and searching for wreckage. Also present are photographs of visitors to the base (including actress Pearl White and possibly other cast members of Pearl of the Army), the New York Times airplane, experimental plane designs (such as a dual engine biplane and innovative wing shapes), and two images showcasing the newly developed Brock Automatic Aeroplane Camera designed for aerial surveillance. Cpl. McDonnell himself may possibly appear in photograph no. 69 posing with a young woman in front of an airplane.

Other locations besides Wilbur Wright Airfield are represented in the album, including storefront views and street scenes in Mineola, New York, which may possibly have been McDonnell’s hometown. Also present are four portraits of Theodore Roosevelt giving a speech in 1917 at a racetrack in Mineola, seven images of Washington, D.C., landmarks (including four directional views taken from the top of the Washington Monument), a view of the Tijuana Fair, the Horton Plaza fountain at the Panama-California Exposition in San Diego, and six aerial photographs showing an unidentified coastal city (likely San Diego) and several ships.

Other photographs produced by Cpl. McDonnell for official U.S. Army purposes differ from those found in this album in terms of their size, content, quality of composition, and attention to staging. It is likely that he took photographs for official (and sometimes classified) purposes in his role as base photographer while also taking his own personal snapshots, the latter of which are what appears to be compiled in this album.

Southeast Asia Art Foundation (SAAF) Archive, 1950s-2003

210 linear feet

Online
The Southeast Asia Art Foundation (SAAF) Archive is composed of approximately 200,000 photographs of Southeast Asia artwork compiled by John Adams Thierry during the latter half of the 20th century. The photos are drawn from approximately 30 different sources, sculptures, or monuments throughout Southeastern Asia that have since been vandalized, damaged, insensitively stored, or destroyed.

Southeast Asia Art Foundation (SAAF) Archive is composed of about 200,000 photographs drawn from at least 30 different sources, including 10,000 photos from sites in Cambodia, Java, and Thailand, 1,100 aerial photos of unexplored archaeological sites, and approximately 3,000 photos from leading art dealers. The collection is housed in a series of black binders and is broken down into 1149 binders of images of objects from various regions and object types, 114 binders with museums' holdings and dealers’ photographs, 24 binders of aerial photographs, 2 binders that contain microfiche, and 3 boxes of photographs. Many of the photos depict sculptures or monuments that have since been vandalized, damaged, insensitively stored, or destroyed. Some of the sculptures have also been sold into private collections and are no longer accessible to the public. The photographs of Yves Coffin, a former French diplomat to Cambodia, are now considered one of the best collections of Cham and Khmer architecture and sculpture. Most of the aerial photographs of Thailand in the mid-1950's came from William-Hunt. Some of the microfiche in the collection came from the National Research Centre of Archaeology on Indonesia from 1901 to 1956, while more microfiche was contributed by the Kern Institute, University of Leiden. In addition to the approximately 100,000 photographs and slides, materials also came from an expedition to Java, which sent Patrick Young to photograph the Buddhist monument of Borobudur. The Department of the History of Art at the University of Michigan organized the expedition, which was partially funded by Southeast Asia Art Foundation and its trustee, John A. Thierry.

The collection also contains vast documentation about the legacy of the artwork and the archive itself, including work from leading scholars such as Carol Stratton, Sarah M. Bekker, A.B. Griswold, and Miriam McNair Scott. John Adams Thierry's research and additional articles are incorporated in the collection.

The photo archive is part of the Southeast Asia Art Foundation Archive, which is now housed in three locations within the University of Michigan. The University of Michigan-Museum of Art houses Thierry's collection of 19 sculptures, while the University of Michigan Library houses Thierry's personal library of books on Southeast Asian Art, many of which are rare or difficult to find.

Vice President for Development (University of Michigan) records, 1948 - 2004

54 linear feet

Online
Records of University of Michigan office (and its predecessor administrative offices) responsible for external fund raising and development activities, including subject files of development officials Arthur Brandon, Lyle Nelson, and Michael Radock; staff files; and photographs.

The records of the Vice President for Development date from 1948 to the present and measure 39.5 linear feet. They reflect the basic concerns of the office for these four decades: preserving and improving the university's public image and planning major fundraising efforts. Unfortunately, both activities are incompletely documented. In the area of public relations the records tend to discuss how immediate problems will be dealt with, rather than overall conceptions of the university's image. The thought behind the innovative fundraising devices created or employed by the office is sometimes recorded through consultant reports, but in general is not well documented.

The manuscript records have been divided into two subgroups, one representing the records of the vice president (or senior staff person, for those years in which there was no vice presidency), the other containing records created by the development office. The Vice Presidents subgroup has been divided by the name of each person who has held the office: Arthur Brandon, Lyle Nelson, and Michael Radock. Researchers should note that since Nelson and Radock used their predecessor's files for some time before inaugurating their own records, the relationship between office tenure and file dates is not an exact one. The Development Office subgroup contains records of that office and its subsidiary units. Several accessions of Development Office records received in 1989 and 1990 have been grouped together as Development Office subgroup: 1989-1990 accessions.
