Caroline Leaf is a Canadian-American filmmaker, animator, director, producer, and tutor. She has produced numerous short animated films since 1968 and is best known as one of the pioneering filmmakers at the National Film Board of Canada (NFB). Her initial technique was animating beach sand on white glass lit from below. The resulting film Sand or Peter and the Wolf (1969) won her a fellowship and the chance to work on a second film. In 1972 she moved to Montreal at the invitation of the National Film Board of Canada where she worked until 1991 producing primarily animated films but also live action and documentary shorts. At the NFBC she further developed her storytelling and animation techniques including using animated painting on glass. Her films have been seen all around the world at film and animation festivals where she has received numerous awards and prizes. She has also served as a jury member at festivals, given many hands-on workshops, and taught at colleges and film schools worldwide.
