Margaret Bert was an American character actress who was most active from the 1930s through the 1950s. She was born on June 4, 1896 in Blackburn, Lancashire. She began her film career during the silent film era, having a small, unnamed role in the 1926 film, The Blackbird, starring Lon Chaney. During her lengthy career, Bert appeared in more than 150 feature films, film shorts, and television shows, mostly in un-credited roles, with many of those being as an unnamed player. Occasionally, she would be given a larger supporting role, such as when she was cast as Mrs. Rogers in the 1947 comedy-drama, Sarge Goes to College. With the advent of television, she would make several appearances on the small screen, including roles on The Roy Rogers Show, The Adventures of Jim Bowie, and The Walter Winchell File.
