Martin was an alumnus of Linfield College, where his father Bernard Martyn, aunt Lillian Turner Millsap and uncle Bill Turner also attended. Martin's first year at Linfield was 1948, and e attended the college not only because much of his family went there, but also because it was affiliated with the Baptist church he went to. Although Martin played shortstop at high school in Twin Falls, Idaho, his baseball coach Henry Lever immediately changed his position to outfielder. Martyn once said of the change, "That was probably a major break for my future." Additionally, Martyn was selected a Northwest Conference All-Star in three consecutive seasons from 1950–1952, while helping lead the Linfield Wildcats to conference championship victories in 1950 and 1951. Academically, Martyn double-majored in mathematics and sociology and he graduated cum laude. While playing professional baseball, he earned his masters degree in education in 1959, studying between seasons. In 2000, Martyn was elected to the Linfield College Athletics Hall of Fame.
