Lawrence Randall Grossmith (29 March 1877 – 21 February 1944) was an English actor, the son of the Gilbert and Sullivan performer George Grossmith and the brother of the actor-manager George Grossmith Jr.
After establishing his career in Edwardian musical comedy in London from the first years of the 20th century until the First World War (except for a brief period in the U.S.), Grossmith left England on an extensive tour of the U.S.
and Australia, playing in both musicals and non-musical plays.
He continued his stage career in England and America from 1924.
From 1933 until his death in 1944, he acted in films as well as on stage.
