Lucy, you got some esplainin’ to do! She may have 114 acting credits to her name, but there’s one role that practically everyone associates with today’s celebrity birthday girl: that of the ditzy, ambitious redhead on the classic sitcom I Love Lucy. Created by Ball and her husband Desi Arnaz, I Love Lucy revolutionized the way sitcoms were filmed by pioneering the 3-camera setup that is still used today! Furthermore, Ball was the first woman ever to own her own studio as the head of Desilu productions. She died in 1989 of an acute aortic aneurysm, but I’m convinced that I Love Lucy will live forever.
