Harold Seymour

Harold Seymour (June 10, 1910 – September 26, 1992) was an American baseball historian and academic who is best known as the co-author of the baseball history trilogy: Baseball: The Early Years, Baseball: The Golden Age, Baseball: The People's Game. Though Seymour was initially credited as the sole author of the highly acclaimed trilogy, his wife Dorothy Seymour Mills was the one who did much of the extensive research and writing for the books.

The Seymour Medal, awarded annually by the Society for American Baseball Research to the best baseball book, is named after Dorothy and Harold Seymour.
