Francis Rogallo (1912-2009) Developed
the Rogallo wing, a flexible wing that earned him the title "father of modern hang gliding." Originally designed to facilitate
the astronauts' landing back on earth from space, the Rogallo wing was adapted for commercial use in hang gliders and kites.
Both Rogallo and his wife, Gertrude, worked
on the design, using curtains for the wing and constructing a wind tunnel in their home to test the wing. In appreciation,
Rogallo applied for the patent in 1948 in her name, and both were inducted into the First Flight Shrine in 1995. Gertrude
died in 2008.
