They mentioned his name on the very first episode. They also mentioned Mary Ann's last name (Summers), and the Skipper's name (Jonas Grumby.) None were ever mentioned again. Gilligan's full name was never mentioned. When questioned about it, producer Sherwood Schwartz said it was "Willie Gilligan". (I'm a big Gilligan trivia geek.)

RIP Professor!
