The Space Race—Astronaut Group 4 (the "Scientists"), Part II
Harrison Hagan "Jack" Schmitt (born 3 July 1935)—He flew Apollo 17 (America & Challenger, 1972); he was the first member of Astronaut Group 4 to fly & the twelfth of the twelve Moonwalkers; he was re-assigned from the cancelled Apollo 18 to Apollo 17 after intense lobbying by other lunar geologists, displacing Joe Engle; he was elected to the U.S. Senate from New Mexico, serving from 1977-1983.

Commentary: Schmitt worked for the U.S. Geological Survey, developing techniques for training astronauts to conduct field geology on the Moon, before his selection as an astronaut in 1965.

As of this publication, Senator Schmitt is still alive, age ninety.
