Incisive, diminutive character actor, often bespectacled, who moved to Hollywood with Orson Welles and the Mercury Theater and is perhaps best remembered for playing Kane's loyal, bespectacled sidekick Bernstein in "Citizen Kane" (1941). Also excellent as the corrupt, crippled lawyer in Welles' "The Lady from Shanghai" (1948) and also in "The Men" (1950) and "Patterns" (1955).
