A. E. Stevenson was born in Brigden, Ontario, Canada on September 10, 1909, the son of naturalized American citizens then residing in Canada. After completing his elementary education in a farm community in Ontario in 1922, he entered the United States at the port of Detroit in the early 1920's and held various odd jobs until he joined the Hudson Motor Company of Detroit in 1929. As a tool and die maker he was asked to join the Mechanics Educational Society of America (MESA) in 1934. He became a leader in an unsuccessful strike in that same year.
Unable to find employment in Detroit after this incident, he moved to Cleveland, obtaining a job at the Globe Machine and Stamping Company where he continued his membership in MESA. In 1936 all employees at the plant voted to affiliate with the UAW and the following April he was elected as a delegate to the Central Labor Body, a forerunner of the Cleveland Industrial Union Council, a position he held until February of 1949 when he was defeated in a CIUC election amid accusations of leftist leanings.
In 1942 and until his induction into the Army in May, 1943, he served on several panels of the War Labor Board and as a member of its Nonferrous Metals Commission.
After February, 1949, A. E. Stevenson left union activities and became a salesman, held several managerial positions, and was, finally, a stockbrocker. He died on January 29, 1976.
