American filmmaker, producer and screenwriter Albert Lewin first worked as an English instructor at the University of Missouri after earning a Master's degree at Harvard. During WW I, he served in the military, and afterwards was appointed assistant national director of the American Jewish Relief Committee; he then became a drama and film critic for the Jewish Tribune until the early 1920s when he went to Hollywood to become a reader for Samuel Goldwyn. Later he worked as a script clerk at another studio before becoming a screenwriter at MGM in 1924. Soon he was promoted to head of the MGM script department; by the end of the decade he had become a close associate and personal assistant to Irving Thalberg. Lewin went on to produce some of the studio's biggest films during the 1930s, but he was usually only credited as an associate producer. Following Thalberg's death, he began working as a producer for Paramount in 1937. In 1942, he made his directorial debut, but over the next 15 years only directed six films, for which he wrote his own screenplays and produced. In 1966, he wrote a novel, The Unaltered Cat.
