Mrs Patrick Campbell (1865-1940), otherwise known as Mrs Pat was born Beatrice Stella Tanner and was a succesful English stage actress. She used her married name as her stage name even after her first husband died in the Boer War in 1900. She later married George Cornwallis-West, a writer and soldier previously married to Jennie Jerome, the mother of Sir Winston Churchill.
Mrs Pat played such famous roles as Hedda in Hedda Gabler, Ophelia in Hamlet, Lady Macbeth and Juliet in Romeo and Juliet. Two years after this portrait was painted, Mrs Pat played Eliza Doolittle in the original West End Production of Pygmalion, specifically written for her by George Bernard Shaw. Bernard Shaw was fascinated with Mrs Pat and began a passionate pursuit, a lengthy exchange of letters, although their relationship was never consummated.
