Rev. George Weir was born on July 22, 1825, in Aberlour, Scotland.

He was a clergyman and educator. He studied at King’s College, Aberdeen, Scotland (M.A., 1848). He began his career in 1848 as an assistant schoolmaster at the Turriff Parish School, Scotland. In 1850, he became a rector of Banff Academy, Scotland. In 1853, Weir moved to Kingston, Ontario, to become a Professor of Classics at Queen’s University (1854-1864). He got dismissed for involving students in a dispute with the principal. Weir sued the university for unjust dismissal and won the initial trial but lost the appeal. Between 1864 and his death in 1891, he worked as a Professor of Greek, Latin, Hebrew, and Church History at Morrin College in Quebec City. In both Quebec and Ontario, Weir was involved in the organization of the educational sector. He also served as an inspector of superior schools in Kingston. In Quebec, Weir was a member and secretary of the Protestant section of the Council of Public Education. In 1881, he received an honorary degree of LL.D. from the University of Aberdeen, Scotland.

In 1856, he married Williamina Lowe (1834–1887). He died on June 12, 1891, in Quebec City, Quebec.
