Bernice Steadman (née Trimble; July 9, 1925 – March 18, 2015) was an American aviator and businesswoman. Steadman was one of thirteen women chosen to take the same tests as the astronauts of the Mercury 7 during the early 1960s. The group later became known as the Mercury 13. However, Steadman and the other twelve women in the program were denied the opportunity to become astronauts due to their gender. Steadman, a professional pilot, later co-founded the International Women's Air & Space Museum in Ohio during the 1980s.
