Thelma Alice Todd was an American actress. Appearing in about 120 pictures between 1926 and 1935, she is best remembered for her comedic roles in films like Marx Brothers' Monkey Business and Horse Feathers, a number of Charley Chase's short comedies, and co-starring with Buster Keaton and Jimmy Durante in Speak Easily. She also had roles in Wheeler and Woolsey farces, several Laurel and Hardy films, the last of which featured her in a part that was truncated by her death.
Todd was born in Lawrence, Massachusetts to Jim and Bertha Todd, and was a bright student who achieved good academic results. She intended to become a school teacher. However, in her late teens, she began entering beauty pageants, winning the title of Miss Massachusetts in 1925. While representing her home state, she was spotted by a Hollywood talent scout and began her career in film.
During the silent era, Todd appeared in numerous supporting roles that made full use of her beauty but gave her little chance to act. With the advent of the talkies, Todd was given opportunity to expand her roles when producer Hal Roach signed her to appear with such comedy stars as Harry Langdon, Charley Chase, and Laurel and Hardy. In 1931 she was given her own series, teaming with ZaSu Pitts for slapstick comedies. This was Roach's attempt to create a female version of Laurel and Hardy. When Pitts left Roach in 1933, she was replaced by Patsy Kelly. The Todd shorts often cast her as a working girl having all sorts of problems, and trying her best to remain poised and charming despite the embarrassing antics of her sidekick.
In 1931, Todd became romantically involved with director Roland West, and starred in his film Corsair.
