Raymond "Ray" Harryhausen was an American visual effects creator, writer and producer who created a brand of stop-motion model animation known as "Dynamation."

He is known for his works on monsters in films. As an homage to that, the restaurant Mike and Celia dined at in the 2001 Disney/Pixar film Monsters, Inc., Harryhausen's, was named after him.

He also did the animation for Mighty Joe Young with Willis O'Brien, which the 1998 film by the same name is a remake of. He also appeared in the film as Gentleman at Party.

Ray ’retired’ from dimensional animation in 1984 although he did indulge himself occasionally, to keep his hand in, on such projects as the UK television documentary Working With Dinosaurs (1999) and the completion of The Tortoise and the Hare, now called The Story of the Tortoise and the Hare (2001/2).
