Flora Finch was born in London, England, on June 17, 1867. After spending time on the legitimate stage, she began to make films, and was one of the early comedy stars of the silent-film era. Her first film was Mrs. Jones Entertains (1909). After making nine more films she began appearing with rotund comic John Bunny, and together they would make more than 250 shorts over the next five years, becoming the cinema's first popular comedy team.
Among their more popular titles were The New Stenographer (1911), The Subduing of Mrs. Nag (1911) and A Cure for Pokeritis (1912). She made other films on her own in addition to those she made with Bunny, and after he died in 1915 she began her own series of comedy shorts, although not meeting with the kind of success she had with Bunny.
By the time the sound era began she was relegated to minor supporting roles and bit parts, although she did have a fairly decent role in The Scarlet Letter (1934) with Colleen Moore, as one of the self-righteous women in Nathaniel Hawthorne's tale of life in colonial America.
Finch retired from acting after appearing in The Women (1939), ending a long and illustrious career. On January 4, 1940, she died of rheumatic fever, brought on by a streptococcus infection, in Los Angeles, California. She was 70 years old.
