The Klapmeier brothers, Alan Lee Klapmeier (born October 6, 1958) and Dale Edward Klapmeier (born July 2, 1961), are retired American aircraft designers and aviation entrepreneurs who together founded the Cirrus Design Corporation in 1984. Under the leadership of the Klapmeiers, Cirrus was the first aircraft manufacturer to install a whole-plane parachute recovery system as a standard on all its models—designed to lower the airplane (and occupants) safely to the ground in case of an emergency. The device is attributed with saving over 200 lives to date. From the brothers' use of all-composite airframe construction and glass panel cockpits on production aircraft, Cirrus is known for having revolutionized general aviation for modern light aircraft pilots.
