Richard "Dick" Horace Battin (March 3, 1925 – February 8, 2014) was an American engineer, applied mathematician and educator who led the design of the Apollo guidance computer during the Apollo missions during the 1960s.
Battin began his career in 1951, serving as the assistant director of the Massachusetts Institute of Technology's (MIT) Instrumentation Laboratory.
Under Battin's leadership, his team created the analytic and software design of the navigation, guidance and control systems for each of the Apollo spaceflights, making the lunar landing of Apollo 11 possible.
After his retirement from Draper in 1987, Battin continued to teach at MIT, where he was a senior lecturer in the Department of Aeronautics and Astronautics until 2010.
In addition to being a Honorary Fellow of the American Institute of Aeronautics and Astronautics (AIAA), Battin was also a Fellow of the American Astronautical Society (AAS), a member of the National Academy of Engineering, and a member of the International Academy of Astronautics.
