CHA SSERIAU, THEODORE (1819-1856), French painter, was born in the Antilles on Sept. 20, 1819, and died in Paris on Oct. 8, 1856. He studied under Ingres at Paris and at Rome, subsequently falling under the influence of Paul Dela roche. In his short life he produced little. There are decorative paintings by him in the church of St. Mery and the Salle des Comptes in the Palais d'Orsay, and some characteristic litho graphs, imaginative in character and original in execution, which link him with the artists of the '7os and '8os rather than with his contemporaries or predecessors.
