A farmer, a university lecturer and a leading agrologist, Wallace Thomson was born at Douglas, Manitoba. He moved with his family to Pense, Saskatchewan, in 1906, settling on a farm purchased by his father, a railway station agent.
Seeking to broaden his knowledge of agriculture, Wallace Thomson enrolled at the University of Saskatchewan. He graduated in 1919 with a bachelor of science degree in agriculture. For the first four years following graduation he instructed in physics at the University of Saskatchewan in winter and farmed at Pense in summer. From 1924 to 1933 he lectured in physics at the University of Manitoba, rising to head of the physics department. In 1934 he returned to Pense to farm full time.
His double career didnít stop him from maintaining an extensive livestock operation. For 30 years he maintained a dairy herd which provided milk for Pense. He also had a Shorthorn beef herd and from 1917 to 1925 he kept a flock of 400 Shropshire sheep. He was in demand all over Saskatchewan as a livestock judge at fairs. In later years he went out of livestock and became a full-time grain farmer.
Mr. Thomson served as president of the Saskatchewan Institute of Agrologists in 1948-49; vice-president of the Agricultural Institute of Canada in 1951-52 and became president of the A.I.C. in 1956-57. For his work as an agrologist, he was named a Fellow of the Agricultural Institute of Canada. He served on the senate of the University of Saskatchewan from 1949 to 1955 and on the board of the Regina Exhibition Association for many decades where he was in charge of 4-H events and farm boys and girls camps.
