Thomas Joseph Kelly (June 14, 1929 – March 23, 2002) was an American aerospace engineer. Kelly primarily worked on the Apollo Lunar Module, which earned him the name of “Father of the Lunar Module” from NASA.
Kelly graduated from Cornell University in 1951, where he was a member of the Quill and Daggersociety. Afterwards, Kelly obtained his MS degree from Columbia University and Ph.D. from the Polytechnic Institute of Brooklyn.
Kelly was the project engineer, engineering manager and deputy program manager for Grumman Aircraft‘s Apollo Lunar Module (1962–1970). His 2001 book Moon Lander: How We Developed the Apollo Lunar Module documents the process of designing, building and flying the Lunar Module.
