Career.
Levitow was born in Los Angeles, California. He began working as an in-betweener and assistant animator at Warner Bros. Cartoons in 1940. Levitow briefly left Warner Brothers when he was drafted during World War II, later returning in the Warner Bros. in 1945. Levitow was later promoted to animator and would receive his first animations credit in 1953 while working under the direction of Chuck Jones. He worked steadily for Jones over the remainder of the 1950s, and directed several cartoons for release in 1959, including the Pepé Le Pew cartoon "Really Scent". While working under Jones, he made characters' joints more angular than most other animators. Those characters with fur (Wile E. Coyote, for example) looked especially shaggy in Levitow's scenes.
Levitow joined UPA in 1958 to work on the Mr. Magoo feature "1001 Arabian Nights", staying behind even after the studio was sold to Henry G. Saperstein. In 1962, he directed the first feature-length animated television special, "Mr. Magoo's Christmas Carol". 1962 also saw the release of his theatrical feature "Gay Purr-ee", with the voices of Robert Goulet, Judy Garland, and others. By 1962, he was working with Jones at MGM as an animator and a director in the Tom and Jerry series. He co-directed the feature film "The Phantom Tollbooth" with Chuck Jones at MGM. In addition, he worked with UPA on more Mr. Magoo cartoons, including "The Famous Adventures of Mr. Magoo". He animated on the Chuck Jones-produced "A Christmas Carol", directed by Richard Williams at Williams' London studio in 1971. His last completed project was "B.C.: The First Thanksgiving" in 1973. 
At the time of his death on May 8, 1975, Levitow was in line to direct the animated feature film "". The project was taken over by Richard Williams when Levitow unexpectedly died during pre-production at the age of 52. Grampa Simpson on "The Simpsons" was named after both Levitow and creator Matt Groening's grandfather (unbeknownst to the writers).
