Happy 75th Birthday to Jim Davis, whose Garfield cartoon is one of the world’s most widely syndicated comic strips. Since 1978, the sarcastic feline has been grinning from pages—and was eventually joined by other Davis newspaper notables such as Tumbleweeds, Gnorm Gnat, and Mr. Potato Head. Garfield was inspired by Davis’s childhood memories growing up on a small farm in Indiana with 25 cats. (1945)
