Myron "Grim" Natwick (né Nordveig; August 16, 1890 – October 7, 1990)[1] was an American artist, animator, and film director.

Natwick found that he was good at this type of work and contacted other publishers in Chicago, eventually illustrating the covers for many song sheets, usually in no more than two colors.

[9] Although legal ownership of the Betty Boop character remained with the studio (as Natwick was an employee), Grim created the original design of Betty Boop at the request of studio head Max Fleischer, who requested a girlfriend for his then-star character, an anthropomorphic dog named "Bimbo".

Natwick would remain one the primary animators of Betty Boop from the Dizzy Dishes to Bimbo's Initiation, his last cartoon for Fleischer's before moving to the West Coast.

Seeing Natwick's animation of Betty Boop in The Bum Bandit promoted Disney to make him an offer, but believing Iwerks to be the real creative force of the two he chose to work at the latter's studio.

[13] At the studio Natwick would direct Flip the Frog, Willie Whopper and Comicolor Cartoons along with many of the same young animators he had supervised at Fleischer.

I asked Ted if he would intercede for me, pick a moment when Walt was in a good mood, and suggest that I would like to join the Disney staff.

[18] In his scenes Natwick brought an expertise to animating human characters which was lacking in Disney's previous effort The Goddess of Spring.

[21] Natwick was given some of the studio's top assistants to work with including, Marc Davis, Lester Novros and Jack Campbell.

He also helped to animate Mickey Mouse in Fantasia, Mr. Magoo, Popeye, Felix the Cat and many other 1940s and 1950s cartoon greats.

Three of Natwick's former assistants included Walter Lantz (Hearst), Chuck Jones (Iwerks) and Marc Davis (Disney).

[25] Natwick died on October 7, 1990, in Los Angeles, California of pneumonia and heart disease, two months after celebrating his 100th birthday, with a party with friends such as Shamus Culhane.
