Roy Williams (July 30, 1907 – November 7, 1976) was an artist and entertainer for The Walt Disney Studios, best known as "Big Roy," the adult mouseketeer for four seasons on the Mickey Mouse Club television series and for his invention of the Mickey Mouse hats.
[1] Williams was born in Colville, Washington and raised in Los Angeles, where he attended Fremont High School.
[2][3] Williams also produced one-panel gag cartoons for The New Yorker, Saturday Evening Post, and other magazines.
[citation needed] Disney director Jack Kinney described Williams as a "big fat balding hot-headed unpredictable bastard", but hugely admired his prolific talent, saying that he could "sit down and grunt out a few pounds of gags as if it were nothing".
[4] The Mouseketeers who worked with him on the original Mickey Mouse Club series, conversely, remembered him fondly.
