DESSOIR, LUDWIG (1810-1874), German actor, whose name was originally Leopold Dessauer, was born on Dec. 15, 181o, at Posen, the son of a Jewish tradesman. He made his first appearance on the stage there in 1824 in a small part. After some experience at the theatre in Posen and on tour, he was engaged at Leipzig from 1834-36. In 1836 he was at the Breslau municipal theatre, and during 1837-39 at Budapest. From there he went to Karlsruhe and in 1847 to Berlin where his success in Othello and Hamlet won him a permanent engagement at the Hof theatre. In 1853 he appeared in London. He retired in 1872 and died on Dec. 3o, 1874, in Berlin. Dessoir was twice married; by his first wife he had one son, the actor Ferdinand Dessoir (1836– 92). In spite of certain physical disabilities Ludwig Dessoir's genius raised him to the first rank of actors, especially as an interpreter of Shakespeare's characters. G. H. Lewes placed Dessoir's Othello above that of Kean, and the Athenaeum pre ferred him in this part to Brooks or Macready.
