Coleman Griffith: Coleman Roberts Griffith (May 22, 1893 – February 1966) was an American sport psychologist.  Born in Iowa, he is considered the founder of American sport psychology.  Griffith studied at Greenville College until 1915, and then studied psychology at the University of Illinois.  While at the University of Illinois, Griffith established what he claimed to be the first sports psychology laboratory in the United States.  At this time Griffith worked closely with the University of Illinois football team, studying how factors such as psychomotor skills and personality variables related to performance and learning of athletic skills.  Due to financial reasons, the Research in Athletics Laboratory eventually was closed, which led to Griffith becoming a sport psychologist with the Chicago Cubs baseball team.  Throughout his time with the Chicago Cubs, Griffith examined the players and completed a series of reports for Philip K. Wrigley, the owner of the Chicago Cubs team, with the results eventually summarized in a large report.  His ideas were met with resistance, but he helped the Cubs to be successful while there.  Griffith ended his career in the department of education at the University of Illinois until his retirement in 1961.  Some of Griffith's main contributions to the field of sports psychology came from his publications "The Psychology of Coaching" (1926) and "The Psychology of Athletics" (1928).  These publications were written during Griffith’s time at the University of Illinois and covered topics such as how a coach must have knowledge in athletics, physiology, and psychology to be successful.  Much of Griffith's research and publications have become the foundation for the widely growing field of sports psychology and many of his ideas are still used today.
