MARIE TEMPEST '(1866-), the stage name of the English actress, née Marie Susan Etherington, who in 1898 ma r ried Cosmo Gordon-Lennox ("Cosmo Stuart"), a grandson of the 5th duke of Richmond, and himself an actor and playwright. She had a charming soprano voice and was educated for the operatic and concert stage, but at first appeared in light comic opera, in which she became very popular. Abandoning music, however, for the comedy stage, she made an even greater success as an actress, notably in Becky Sharp (1901); and under her own management in later years she produced a succession of modern comedies, in which her capacity for rivalling in London the triumphs of Rejane in Paris was conspicuously displayed.
