William Henry Allison (June 14, 1838 – December 15, 1934) was a Canadian politician and school lands commissioner. He was elected as a Conservative to the House of Commons of Canada in the 1878 election in the riding of Hants and re-elected in 1882.[1]
Allison was the son of James Whidden Allison, who had served as a member of the provincial assembly, and Margaret Elder.[2] Allison was educated in Sackville, New Brunswick and later was a captain in the local militia.[3] Between 1871 and 1878, he was a member of the Legislative Assembly of Nova Scotia for Hants County. Allison ran unsuccessfully for a seat in the House of Commons in 1874.[1]
His brother David served as president of Mount Allison University. He moved to Chamberlain, South Dakota for his health. As his health continued to decline he became a pauper and became dependent on public charity. He died at age 96.[4]
