Roland Michel Barrin Gallissonniere, marquis de la, a French admiral, born in Roche-fort, Nov. 11, 1693, died at Nemours, Oct, 26, 1756. After rising through various grades in the navy, he was appointed governor general of Canada in 1747, that province being under the management of the navy department. He at once studied the resources, wants, and advantages of Canada, and maintained its defence till the peace of Aix-la-Chapelle. His precautions then to secure all doubtful limits for France showed his energy. He endeavored in vain to obtain from government the establishment of a printing press in Canada. In 1749 he returned to France and was made commodore. He defeated Byng at Minorca in 1756. He was an able naval commander, a wise governor, and a devoted student of science.
