Harry Shapland Colt and Charles Hugh Alison parlayed their golfing skills, Cambridge and Oxford education, and secretarial positions at high end Ascot area clubs to create the first golf course architecture firm. Based in England with offices in London, Detroit, and Paris they designed courses on four continents through the first half of the twentieth century. Even with their world wide fame and influence to the present day, less than forty of these courses were created in North America and only thirty remain. Captain Charles Hugh Alison spent the 1920s sketching his way across the Midwest and East Coast of the United States and Canada. He followed mentor and partner Harry Colt, who came to America for three short visits before World War I. In 1920 Alison established a permanent office in Detroit for their newly formed firm. Along with over thirty new courses and multiple renovations, Alison revised many of his partner’s original designs. Harry Colt and Hugh Alison designed, revised, and influenced many of the Golden Age classics we still revere today: Pine Valley, Old Elm, Milwaukee, Toronto, Kirtland, Bloomfield Hills, Orchard Lake, Davenport, Hamilton, and the Country Club of Detroit. In these pages we chart their North American efforts under the firm’s banner: Colt and Alison golf course architects – London Detroit and Paris.
