CLARKE, JOHN SLEEPER (1833–1899), American actor, was born in Baltimore, Maryland, on the 3rd of September 1833, and was educated for the law. He made his first appearance in Boston as Frank Hardy in Paul Pry in 1851. In 1859 he married Asia Booth, daughter of Junius Brutus Booth, and he was associated with his brother-in-law Edwin Booth in the management of the Winter Garden theatre in New York, the Walnut Street theatre in Philadelphia and the Boston theatre. In 1867 he went to London, where he made his first appearance at the St James’s as Major Wellington de Boots in Stirling Everybody’s Friend, rewritten for him and called The Widow’s Hunt. His success was so great that he remained in England for the rest of his life, except for four visits to America. Among his favourite parts were Toodles, which ran for 200 nights at the Strand, Dr Pangloss in The Heir-at-law, and Dr Ollapod in The Poor Gentleman. He managed several London theatres, including the Haymarket, where he preceded the Bancrofts. He retired in 1889, and died on the 24th of September 1899. His two sons also were actors.
