William Wrightson Eustace Ross (June 14, 1894 – August 26, 1966) was a Canadian geophysicist and poet. He was the first published poet in Canada to write Imagist poetry, and later the first to write surrealist verse, both of which have led some to call him "the first modern Canadian poet."
Ross was born in Peterborough, Ontario, to Ralph and Nellie Creighton Ross. He grew up in Pembroke, Ontario. He studied geophysics at the University of Toronto., supporting his studies with summer work on geological surveys in Northern Ontario.
Ross served with the Canadian Expeditionary Force in World War I as a private in the signal corps. On his return, he worked until his retirement as a geophysicist at the Dominion Magnetic Observatory at Agincourt, Ontario (now part of Toronto). On June 3, 1924, he married Mary Lowrey, "the well-known journalist." They had two children, Mary Loretto and Nancy Helen. The family bought a house on Delaware Ave. in Toronto, where Ross lived for the rest of his life.
Ross began writing poetry in or around 1923. His earliest works "are written in free verse and reflect a knowledge of both imagism and Japanese poetry." In 1925 Ross developed the 'laconic' as a distinctly Canadian verse form, "one that would be 'native' and yet not 'free verse,' one that would be unrhymed and yet definitely a 'form.'"
