Adolf von Sonnenthal (21 December 1834 – 4 April 1909), Austrian actor, was born of Jewish parentage in Budapest. Though brought up in penury and apprenticed to a working tailor, he cultivated his talent for drama, and was fortunate in receiving the support of a co-religionist, the actor Bogumil Dawison, who trained him for the stage. He made his first appearance at Temesvar in 1851, and after engagements at Hermannstadt and Graz came in the winter of 1855-1856 to Königsberg in Prussia. His first performance was so successful that he was engaged by Heinrich Laube for the Burgtheater in Vienna, making his first appearance as Mortimer in Schiller's Maria Stuart.
