Marion Frank Rudy (24 January 1925 – 13 December 2009) was the aeronautical engineer who patented a cushioning system based on an inert gas encapsulated in polyurethane plastic. It was trademarked by Nike as the "Air" sole. He was a member of Case Western Reserve University's class of 1950, and a graduate of Fairview High School, in Fairview Park, Ohio. He was also a member of the Phi Kappa Tau fraternity.[1]
The 19 varsity athletic teams at his alma mater, Case Western Reserve Spartans, wear a special patch on their uniforms commemorating him and his invention. The emblem has Rudy's initials, MFR, with a 3D design of special texture and shine to resemble inflated air sole look, and has orbiting planets pay tribute to his career as an aerospace engineer.[2]
Rudy died in his home in California on December 13, 2009. He was 84 years old.[3]
