Cal Marvin, a member of the U.S. Hockey Hall of Fame for his 50 years of work with the sport, has died at the age of 80. Marvin helped establish the northern Minnesota town of Warroad as "Hockeytown USA." Over the years, Warroad, which has less than 2,000 residents, produced an impressive string of Olympians, professional standouts and amateur stars. In the late 1940s, Cal Marvin founded the fabled Warroad Lakers, a senior league team of post-collegiate stars that skated with the best in the world. Marvin also helped found the men's hockey program at the University of North Dakota where he played collegiate hockey. Morning Edition host Cathy Wurzer talked with Marvin last year.
