Adler was born on January 22, 1884, in
Chicago,
Illinois. He started as a vaudeville actor and then became a title writer for
Mack Sennett silents in the early 1920s, easing into talkies with three Harold Lloyd features and as a staff writer for the Columbia Pictures Short Subject department, a position he held until its demise in 1957. While the vast majority of Adler's writing credits were for Sennett and Three Stooges short subjects, Adler co-wrote six features for
Laurel and Hardy and two for
Abbott and Costello. A resident of Hollywood Hills, he was sociable, chatting with neighbors at the Beachwood Village Laundry and giving pocket money to local children. His house became a stop-off for neighbors on their way to and from the Beachwood Market because he would invariably invite them in for a refreshment. ==Death==
