Myron "Grim" Natwick (August 16 1890 - October 7 1990) was an American animator and film director, regarded as one of the greatest of all time. Best known for creating the Fleischer Studio's most popular character, Betty Boop, Natwick worked for a number of American animation studios, including the Ub Iwerks studio, Walt Disney Productions, the Walter Lantz studio, UPA, and the Richard Williams studio. At Disney, Natwick was a lead animator on Snow White and the Seven Dwarfs, and was instrumental in bringing the titular heroine to life.
Natwick was a native of Wisconsin Rapids, Wisconsin. He died in Los Angeles, California of both pneumonia and a heart attack, just after having a one-hundredth birthday party with friends such as Shamus Culhane.
