Carrying on the tradition of Disney corporate educational films, was the Bell Science Series, produced by Jack Warner for Bell Telephone. With several of the episodes written and directed by Frank Capra, and animation direction by such notable artists as Chuck Jones, Fritz Freleng and Shamus Culhane, the series attempted to explain scientific phenomena such as the nature of time (about time (1959)), the functioning of the human body (Hemo the magnificent, 1958), the importance of heredity and environment in determining human traits (the Thread of Life, 1957), and the mysteries of the universe (The Strange Case of Cosmic Rays. 1957), among others.
