Wally Schirra (1923-2007)

Walter M. “Wally” Schirra Jr., who as one of the original Mercury Seven astronauts combined the Right Stuff — textbook-perfect flying ability and steely nerves — with a pronounced rebellious streak, died Thursday at 84.

He was the only astronaut to fly in all three of NASA’s original manned spaceflight programs: Mercury, Gemini and Apollo.
