From 1949 until 1990, Dorothy Jane Mills quietly contributed her research and writing to the first baseball histories ever written by a historian. The wife of historian Harold Seymour, she found herself increasingly involved with his books, as the couple presided over mountains of records on the game and worked to prepare his imposing manuscripts for press. But she received no official credit. It was after Dr. Seymour's passing that other researchers learned she was the unattributed co-author of much of his work.

This important memoir reveals details of the author's partnership with baseball's most revered historian. Many new facts regarding Mills' role come to light. Mills, now recognized as the game's first woman historian, also explains how her work as a teacher, editor, novelist, children's author, and public speaker fit into her baseball work. The book contains numerous photographs from the author's personal collection, most of them in print for the first time as well as a foreword by Steve Gietschier of The Sporting News.
