Alan LaVern Bean (born March 15, 1932) is a former NASA Astronaut and became the fourth man to walk on the moon at the age of thirty-seven years in November 1969.

Bean was born in Wheeler in the northeastern Texas Panhandle. He is of Scottish descent. As a boy, he lived in Minden, the seat of Webster Parish in northwestern Louisiana, where his father worked for the Soil Conservation Service. Bean graduated from R. L. Paschal High School in Fort Worth, Texas. He received a bachelor of science degree in aeronautical engineering from the University of Texas at Austin in 1955. At UT he was a member of Delta Kappa Epsilon fraternity. After a four year tour as a fighter pilot assigned to a jet attack squadron in Jacksonville, Fla.[1], he trained as a Navy Test Pilot where his instructor was his future Apollo 12 Commander Pete Conrad. He was awarded an honorary doctorate of science from Texas Wesleyan College in 1972, and was presented an honorary doctorate of engineering science degree from the University of Akron (Ohio) in 1974.

Hmm and his Apollo Mission..

Bean was selected by NASA as part of group 3 in 1963. He was selected to be the backup Command Pilot for Gemini 10 but was unsuccessful in securing an early Apollo flight assignment. He was placed in the Apollo Applications Program in the interim. When fellow astronaut Clifton Williams was killed in an air crash, a space was opened for Bean on the back-up crew for Apollo 9.
Apollo 12 Commander Conrad, who had instructed Bean at the Naval Flight
Test School years before, personally requested Bean to replace Williams.
Bean was the lunar module pilot on Apollo 12, the second lunar landing. In November 1969, Al Bean and Pete Conrad landed in the moon’s Ocean of Storms—after a flight of 250,000 miles and a launch that included a harrowing lightning strike. Bean was the astronaut who executed John Aaron’s
famous “Flight, try SCE to ‘Aux’” instruction to restore telemetry
after the spacecraft was struck by lightning 36 seconds after launch,
thus salvaging the mission. They explored the lunar surface,
deployed several lunar surface experiments, and installed the first
nuclear power generator station on the moon to provide the power
source. Dick Gordon remained in lunar orbit photographing landing sites for future missions.

How come No one Remembers him?… I mean Neil Armstrong,Edwin “Buzz” Aldrin,Michael Collins is in the science books..
