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 8–19.
Marshall insisted that Capablanca be permitted to enter the San Sebastian tournament in 1911.
