Collection consists of microfilm of scrapbooks of clippings and memorabilia relating to William Ivy, a professional acrobat, aviator, and balloonist. Born in Texas, William Ivy joined with Thomas S. Baldwin in 1889 to form a team that performed balloon ascensions, parrachure drops, and other acrobatic and aeronautical exhibitions throughout the United States and abroad. In that same year Ivy changed his name to Ivy Baldwin. He performed exhibitions at Elitch Gardens and at Manhattan Beach in Denver, and also served as an aeronaut with the U.S. Army Balloon Corps, located at Fort Logan. He later built and operated dirigibles, airplanes, and regularly performed a wire-walking act over Boulder Creek near Eldorado Springs, Colorado. The location of the original documents is unknown.
