Career
Born at Sibsey, Lincolnshire, on 6 April 1772, Marrat was self-taught through wide reading and study of modern language. While at Boston, Lincolnshire, he for some years worked as a printer and publisher. In 1811-1812 he, in conjunction with Pishey Thompson, ran The Enquirer, or Literary, Mathematical, and Philosophical Repository, Boston.
At other times Marrat was a teacher of mathematics, in Lincolnshire and elsewhere.
He lived in New York from 1817 to 1820, and edited there The Scientific Journal (imprint "Perth Amboy, North J and New York", 1818, nine numbers). He returned to England, and at Liverpool, where he settled in 1821.
George Boole taught at his school, in 1833. He died suddenly there on 26 March 1852, and was buried at the necropolis near that city.
