On this day in 1946, the Percy Jones Army Hospital in Battle Creek (formerly the Battle Creek Sanitarium) installed the nation’s first microfilm projector. The device, made by University Microfilms and Argus Cameras of Ann Arbor, was used to project enlarged images on the ceilings of rooms of their bedridden patients.
University Microfilms, founded in 1938, has gone one to become a global information technology company and is still based in Ann Arbor. In 1999, the company renamed itself ProQuest. The company has grown from a publisher and archiver of doctoral dissertations into a company that archives and disseminates newspaper articles, scholarly journals, Congressional information and ebooks. It has also been declared an offsite repository by the U.S. Library of Congress for American dissertations.
