Purdue Libraries' collection of primary source materials on the history and development of powered flight began in 1940 with the gift of aviator Amelia Earhart's papers by her husband, George Palmer Putnam. Since that initial donation, the number of flight-related archival collections has increased to reflect the steady growth of faculty and alumni contributions to the development of flight and later, space exploration. The Barron Hilton Flight and Space Exploration Archives was established in 2011 with generous support provided by Barron Hilton and the Conrad Hilton Foundation and now includes the papers of engineers, aviation professionals, scholars, and astronauts including Purdue distinguished alumni such as Neil A. Armstrong and Eugene Cernan. To learn more about the collection and the type of materials being sought, please visit the Collection Focus page.
