Frank James Marshall (August 10, 1877 – November 9, 1944), was the U.S. Chess Champion from 1909-1936, and was one of the world's strongest chess players in the early part of the 20th century.
Marshall was born in New York City, and lived in Montreal, Canada from ages 8 to 19. He began playing chess at the age of 10 and by 1890 was one of the leading players in Montreal.
He won the U.S. chess championship in 1904, but did not accept the title because the current U.S. champion, Harry Nelson Pillsbury, did not compete.
