A. Leo Stevens (1876-1944) was an inventor who contributed to aviation safety through a work in parachute design. In 1909 he invented the Stevens Safety Pack, the first packback style free opening parachute. In 1942, he invented a delayed opening parachute. Edward Boland (1892-1967) worked in association with Stevens and co-invented the elastic parachute shroud line to reduce opening shock. The collection consists of posters, commerative medals, news clippings, and other items commemorating Stevens and Boland’s contrubutions to aviation.
