Catherine Townsend Johnson (1904-75) studied at the American Academy of Dramatic Arts and starred in many Broadway productions, predominantly serious dramas, throughout the 1920s.
Following her marriage to director John Cromwell, Johnson moved to Los Angeles in 1928. She was brought to Metro-Goldwyn-Mayer by Cecil B DeMille, who had himself only just moved to the studio, to star in Dynamite (1929), his first sound picture.
Johnson went on to make regular film appearances, including as the title character in DeMille’s Madam Satan, but only made 23 in total, most of them in the pre-code era. She also continued to appear on the stage, returning to Broadway in 1947 in the original production of State of the Union.
Johnson worked less in the 40s and 50s, devoting time to raising her sons, one of whom was the actor James Cromwell.
