Ice hockey career While studying at the Johns Hopkins University Mitchell played on the university ice hockey team. In February 1896 he was a part of the Johns Hopkins team that played against the Yale University team in the first two intercollegiate ice hockey games in the United States. The Johns Hopkins team also played six games against the Baltimore Athletic Club during the 1895–96 season, and one game against an All-Washington aggregation. As an ice hockey player Mitchell played predominantly at the point position which is an archaic ice hockey position equivalent to a defensive defenseman today. Mitchell also played with the university team during the 1896–97 and 1897–98 seasons. Family In December 1899, Mitchell married Milly Gray Dumble, the daughter of Edwin Theodore Dumble, who was then the State Geologist of Texas and was later Consulting Geologist of the Southern Pacific Railroad, an expert in petroleum production. The Mitchells' son, Allan (1902–1963), was chair of the Indiana University Physics Department from 1938 to 1963 and pioneered the creation of the IU Cyclotron Facility in 1941 (one of the first in the world). Allan's daughter was economist Alice Mitchell Rivlin. Samuel Alfred Mitchell died in Bloomington, Indiana in 1960, aged 85.
