Bertram was born in 1881 at Dissington, near Stamfordham in Northumberland.[2] He was a younger son of James Bertram, a coachman in service at Dissington Hall, and his wife, Isabella.[5] The 1901 Census lists him as a merchant's clerk living with his widowed mother in Newcastle.[6]
Bertram played for South Shields,[1] and continued his career with Northern League club Darlington. He played in all four of their matches in the 1907–08 FA Cup, scored in two, and signed on for the following season in the North-Eastern League, when he remained a regular in the team and again played in all their FA Cup ties.[11][12] In July 1909, he married Ada, the eldest daughter of James Lunn, Newcastle City Councillor and chairman of Newcastle United F.C., at Brunswick Wesleyan Chapel.[13] In October, he resumed his football career with South Shields Adelaide,[14] finished the season with a runners-up medal in the Durham Senior Cup,[15] and vice-captained the side in 1910–11.[16]
He was by this time employed as a commercial clerk and living with Ada in a large house in Monkseaton.[2] The 1939 Register finds him working as an electricity supply salesman, living with Ada and two adult children at the same address,[17] where he died three years later at the age of 61.[3]
