Edgar Dean Mitchell (September 17, 1930 – February 4, 2016) was a United States Navy officer and aviator, test pilot, aeronautical engineer, ufologist, and NASA astronaut. As the Lunar Module Pilot of Apollo 14 in 1971 he spent nine hours working on the lunar surface in the Fra Mauro Highlands region, and was the sixth person to walk on the Moon.

Before becoming an astronaut, Mitchell earned his Bachelor of Science degree in Industrial Management from Carnegie Institute of Technology and entered the United States Navy in 1952. After being commissioned through the Officer Candidate School at Newport, Rhode Island, he served as a Naval Aviator. In 1961, he received his second bachelor's degree, in aeronautical engineering, from the U.S. Naval Postgraduate School and three years later earned his doctorate in Aeronautics and Astronautics from the Massachusetts Institute of Technology (MIT). From 1965 to 1966, he attended the U.S. Air Force Aerospace Research Pilot School and graduated first in his class. During this period, he served as an instructor in advanced mathematics and navigation theory for astronaut candidates.

The legacy of his post-NASA scientific and parapsychology work is carried on through the Institute of Noetic Sciences.
