He published his first book in 1958, a novel called
The Professional, the story of a young fighter pursuing the
middleweight boxing championship.
Ernest Hemingway called the book "the only good novel I've ever read about a fighter, and an excellent novel in its own right." Heinz edited two boxing anthologies,
The Fireside Book of Boxing and
The Book of Boxing with Nathan Ward. Heinz's additional books include
Run to Daylight with football coach
Vince Lombardi,
The Surgeon,
Emergency and
Once They Heard the Cheers, in which the author travels the country revisiting sports heroes of his past. He also wrote the highly acclaimed magazine article, "The Rocky Road of Pistol Pete" about a baseball player,
Pete Reiser, who fought through countless injuries to play the game that he loved. In the late 1960s, Heinz collaborated with
H. Richard Hornberger to write the novel
MASH, published under Hornberger's pen name Richard Hooker. The book was the precursor to the film
MASH, which won the award for best film of the 1970
Cannes Film Festival and an Academy Award for best screenplay based on another medium in 1971. The book also served as the prototype for the long-running, Emmy Award-winning
television series. In 2015, the Library of America published a collection of his best sportswriting,
The Top of His Game. A collection of Heinz's war writings including his dispatches from Europe and some post-war articles were republished in his book,
When We Were One: Stories of World War II. ==Other==
