Did You Know?
As Superman fans know, Brainiac was the superintelligent villain in the Action Comics series and its spin-offs. His name is a portmanteau of brain and maniac. You don’t need x-ray vision to see the connection here—etymologists think Superman’s brainy adversary is the likely inspiration for the common noun brainiac. The term was not coined right away though. The comic-book series was launched in 1938 and the character Brainiac debuted in 1958, but current evidence doesn’t show general use of brainiac to refer to a superintelligent person until the 1970s.
