Harold A. Reid (1925–1992), also known by the pen name H. Reid, was an American writer, photographer, and historian. Reid's photographs of steam locomotives, captured the last days of steam motive power on America's Class I railroads, notably on the Virginian Railway, and ending with the Norfolk and Western in 1960, the last major U.S. railroad to convert from steam. In The Virginian Railway, published in 1961, Reid combined photography with a storytelling style and depth of facts recording the "Richest Little Railroad in the World" before it merged merger in 1959.
