Worked as a film editor in movies and television from the 1930's through the mid-1960's. During this period he worked for Charlie Chaplin's studio, Columbia Pictures, Roy Rogers, and others. He was employed for a time by evangelist Billy Graham, whom he said was his favorite employer due to Graham's gentle management style. In contrast, much earlier in his career, Berlin left Chaplin' s studio because he disliked the way in which Charlie Chaplin mistreated his brother Sidney.
