Doc Marshall (catcher)

William Riddle Marshall (September 22, 1875 in Butler, Pennsylvania – December 11, 1959 in Clinton, Illinois), was a professional baseball player who played catcher from 1904 to 1909. He briefly managed the Chicago Whales during the inaugural Federal League season.
In 1907, while playing for the Cardinals he led all catchers in assists and errors.
Marshall was purchased by the Chicago Cubs on May 29, 1908 and made a number of appearances that season, but did not play in the 1908 World Series for the champion Cubs.
He also played with the Des Moines Undertakers of the Western League and the Milwaukee Brewers and St. Paul Saints of the American Association.
During his baseball career, in both the minor and major leagues, Marshall studied medicine part-time, earning his doctorate in 1909. After retiring from baseball, he bought the practice of a local doctor in the small town of Clinton, Illinois, and served patients in east-central Illinois for 45 years from 1914 to 1959. His brother Dr. E.H. Marshall was his business and professional partner.
He attended college at Grove City College, Slippery Rock University, the University of Pennsylvania and the Chicago College of Medicine and Surgery.
