Scope and arrangement
Collection contains approximately 5,700 loose 4" × 6" and 8" × 10" black and white photoprints, organized by location and then date as noted on their original boxes, followed by nine scrapbooks. The scrapbooks, arranged alphabetically by title, contain mounted photographs organized by subject or trip. Many photographs include detailed handwritten or typed captions on the back.
Most of the photographs in the collection contain images of buildings, streetcars, elevated subway lines, and boats in New York City, New York State, and surrounding areas. Included are many photographs of the Ex-Lax building at 423 Atlantic Avenue in the Fort Greene-Boerum Hill neighborhood of Brooklyn, where Hubacher was employed as a research chemist. In addition to images of the building's exterior and surroundings, Hubacher also took individual and group portraits of Ex-Lax's employees in their offices and laboratories. Also present are many photographs of Long Island, including class portraits of students at the Hewlett School in East Islip, a 1950 Ringling Bros. circus, various historic houses and buildings, and New York World's Fairs in 1939-1940 and 1964-1965.
Many travel photographs also document city scenes, small towns, and landscapes in Switzerland, France, Germany, Italy, the United States, and Canada. These often feature trains and train stations, many of which were shot during Hubacher's long train journeys across the United States and Canada, especially along the routes of the Union Pacific Railroad, the Northern Pacific Railway, and the California Zephyr line spanning from California to Illinois. Travel photographs also show national parks in Colorado, Utah, Montana, and Wyoming; streetcars in Chicago, Saint Louis, Montreal, and Seattle; and family houses and farms in West Virginia, Pennsylvania, and Switzerland. Many family portraits and group portraits of students at the University of Bern are also included. Some prints, dated 1883-1916, were made by Hubacher from old Swiss negatives taken by an unknown family photographer.
