Charles "Charlie" Gustav Thorson (29 August 1890 - 7 August 1966) was a Canadian political cartoonist, character designer, children's book author and illustrator. Thorson is best known as the man who designed an early version of the then yet unnamed Bugs Bunny.
From 1935 to 1945, Thorson worked in American animation studios, including The Walt Disney Company and Warner Bros. He contributed sketches of hundreds of cartoon characters, including Snow White, Elmer Fudd, Little Hiawatha, Sniffles the Mouse, Bugs Bunny, and Inki.
