Aldrin changed name to 'Buzz' as sister called him 'Buzzer'
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.
