Buzz Aldrin was born in 1930 in New Jersey and got his nickname "Buzz" from his sister, who couldn't say "brother" as a baby. He graduated from West Point and was a fighter pilot in the Korean War, completing 66 combat missions. Aldrin is best known as the second person to walk on the moon as part of the Apollo 11 mission in 1969, following Neil Armstrong. Today, at age 83, Aldrin remains one of the few people to have ever walked on the lunar surface.
