George Schley Stillman (December 13, 1879 – March 15, 1907) was an American football player and coach.
He played college football at Yale University where he was selected as a first-team All-American at the tackle position in both 1899 and 1900.
[3][4][5] Stillman was one of the leaders of the 1900 Yale team that finished its season with a perfect 13–0 record, outscoring opponents by a combined score of 336 to 10.
[10] For that 14-year span, the Yale football team has been recognized retrospectively (except for the contemporaneous Whitney) as the national championship team by one or more of the major national championship selectors for six seasons – 1900 (Billingsley, Helms, Houlgate, National Championship Foundation, Parke Davis), 1902 (Parke Davis), 1905 (Parke Davis, Whitney), 1906 (Billingsley, Parke Davis, Whitney), 1907 (Billingsley, Helms, Houlgate, National Championship Foundation, Parke Davis, Whitney), and 1909 (Billingsley, Helms, Houlgate, National Championship Foundation, Parke Davis).
[1][14][15] In April 1906, he married Estelle Barbour of Detroit, Michigan, at New York's Fort Street Presbyterian Church.
