One of hockey's true mystery men, Paul Jacobs played one NHL game with the Toronto Arenas during the second year of the NHL in 1918-19. Between 1917 and 1925 he bounced around several amateur and senior leagues in Canada and the United States.
After averaging more than a goal per game for the Montreal Stars of the City League in 1917-18, he joined the Arenas for one match the following year. After his lone NHL appearance, Jacobs returned to the stars where he continued to excel.
He played for Laval University the next seasons then took a year away from the game. Jacobs' last four seasons were spent with the Quebec Voltigeurs of the QPHL, the Montreal National of the ECAHA and in the USAHA with two Cleveland teams, the Indians and the Blues.
