Thomas Gawthrop "Doggie" Trenchard (May 3, 1874 – October 16, 1943)[1] [2] [3] was an All-American football player at Princeton University in 1893 and a college football head coach at the University of North Carolina at Chapel Hill, the University of Pittsburgh, and West Virginia University.
Trenchard was born in Queen Anne's County, Maryland.[4] During his early coaching career, Trenchard was a professional football player from 1895 until 1898 for the Latrobe Athletic Association and the Allegheny Athletic Association. He also played for the 1898 Western Pennsylvania All-Star football team, formed by Latrobe manager Dave Berry.[5] [6] [7]
In 1895, and from 1913 to 1915, he coached at North Carolina, where he compiled a 26–9–2 record. His best season there came in 1914, when North Carolina started the season 10–0 before losing its final game to Virginia. In 1896, he coached at West Virginia and compiled a 3–7–2 record. In 1897, he coached at Pittsburgh, and compiled a 1–3 record.
He is erroneously referred to as "T. C. Trenchard" in most North Carolina football media guides.
