British actress renowned for the excellence of her performances on the stage and in motion pictures.

After finishing high school, Robson studied at the Royal Academy of Dramatic Art in London and made her first professional appearance at the Shaftesbury Theatre, London, in 1921. She performed in repertory companies until 1924, when she left the theatre because of dissatisfaction with her professional progress. After taking a job in a food-processing factory, she formed an amateur theatrical group among the workers there. She later credited this experience with enlarging her view of dramatic structure and acting.

Robson returned to professional acting in 1929 and in 1931 won wide acclaim for her performances in Eugene O'Neill's Desire Under the Elms and James Bridie's The Anatomist. She soon gained a reputation for playing a wide range of roles. She appeared in motion pictures first in England in 1933 and later in Hollywood, made her stage debut in the United States in 1940, and began a television series in 1974. She appeared in more than 100 stage plays and 60 motion pictures. In 1952 she was named a Commander of the Order of the British Empire and in 1960 was elevated to the British peerage as Dame Commander of the Order of the British Empire.
