The second man to walk on the Moon, Buzz Aldrin was born Edwin Eugene Aldrin Jr. on January 20, 1930, in New Jersey, US. Aldrin earned the nickname "Buzz" as a child when his sister mispronounced the word "brother" as "buzzer", which the retired NASA astronaut made his legal first name in 1980s. Interestingly, his mother's name was Marion Moon.
