Actor
May 30, 1897 · London, England, UK
A fourth-generation actor on her father's side, she trained at the American Academy of Dramatic Arts. Her stage acting career stretched from The Scrap of Paper in 1917 through to Noël Coward's musical Sail Away on Broadway in 1961. She was first noticed by the critics in the 1919 play The Famous Mrs. Fair, which she appeared in with Henry Miller and Blanche Bates. In 1921 she played the tubercular patient Eileen Carmody in Eugene O'Neill's The Straw, and in 1945 she originated the role of Kay Thorndike in the Pulitzer Prize-winning play State of the Union. Gillmore appeared regularly with the Theatre Guild.
Having appeared as an extra in a silent film for the Vitagraph Studios in 1913 aged 16, and in a short, The Home Girl in 1928, Gillmore made her film debut in a major role in 1932 in Wayward, but did not appear on screen again until the 1950s in such films as Cause for Alarm!, Perfect Strangers, High Society (1956) and Upstairs and Downstairs (1959).
