Creamer was one of the first hired on the staff of
Sports Illustrated in 1954. He served the magazine as a senior editor from inception to 1984, and wrote the weekly Scorecard section of the magazine. He also wrote for
The New York Times. As an author, Creamer wrote what many consider the definitive biography of
Babe Ruth, titled
Babe: The Legend Comes to Life, in 1974. Reviewing the book for
The New York Times Book Review,
Roger Angell wrote that Ruth had "at last found the biographer he deserves in Robert Creamer." Creamer wrote seven other baseball related books, including a biography on
Casey Stengel titled
Stengel: His Life and Times in 1984. Additionally, he co-wrote several autobiographies and books, notably with
Ralph Houk, sportscaster
Red Barber and umpire
Jocko Conlan. He also wrote ''Baseball in '41: A Celebration of the "Best Baseball Season Ever"'' (1991). Creamer's lone novel,
A Resemblance to Persons Living and Dead, is loosely based on politics, personages, and the environs of Tuckahoe and the town of Eastchester, New York. In retirement, Creamer occasionally wrote retrospective articles for
SI and could be seen on television commenting on historical moments in sports, many of which he had covered. Creamer was a recipient of the 2012 Henry Chadwick Award from the
Society for American Baseball Research (SABR). He also appeared in
Ken Burns' documentary
Baseball and numerous other television baseball programs, including
When It Was a Game. ==Personal life and death==
