A native of Charleston, Illinois, Walter Moore was twenty-three when he landed his first job, in 1893, as a turf writer with The Western Horseman. Shortly after the turn of the century he joined the prestigious Horse Review, where he proved his value not only as a knowledgeable writer of harness racing, but also as a business man, with annual solicitations of advertising in the journal. When The Horse Review ceased publication in 1932, Moore joined the newly founded Harness Horse magazine. He was its editor until his death in 1948 at age seventy-eight.
Published in the Harness Racing Museum's 1994 book, The Immortals
