Born in 1894 and dead by 1940, Hugh Sterling Eayrs was a Canadian author and publishing professional. Available records connect him with Macmillan of Canada, and surviving public-domain listings show a small but interesting body of work under his name, including the historical biography Sir Isaac Brock.
He also collaborated with Thomas B. Costain on The Amateur Diplomat, which suggests a writer comfortable in both nonfiction and fiction. That mix helps explain his appeal today: his books belong to a period when publishers, editors, and authors often moved in the same close literary circles.
Although detailed biographical information appears to be limited online, Eayrs remains a notable figure for readers interested in early Canadian writing and publishing. His work offers a snapshot of Canada's literary culture in the years between the world wars.
