Today sees the release of Munson: The Life and Death of a Yankee Captain, by Marty Appel. Munson is an in-depth biography of the former captain by the man who helped him write his autobiography. As Appel reports, Munson was reluctant to include much about his personal life when he and Marty undertook the original project. This biography was Appel's chance to delve a little deeper into aspects of Munson's life he was not comfortable sharing himself.
That is not to say, however, that the book focuses solely on his personal life. Munson's life is narrated in the context of his athletic career (including his exploits from childhood on). By the end of the book, you will know Munson very intimately.
In many ways this book is not just about Munson's life and time in New York, it is also about the Yankees during the Munson era. If you're interested in what the transition was like from corporate control (CBS still owned the Yankees in the early years of Munson's tenure) to that of The Boss, you should definitely read the book.
The only thing I would caution is that the book is very detailed when it comes to Munson's career. So if all you care about is what the '78 Yankees were like, or Appel's account of the plane crash, you may find it slow going when reading about Munson's college baseball career at Kent State or the April slumps of his first couple years with the Yanks. But if you're interested in Munson's life, and in getting a sense of the Yankees as an organization in the early Steinbrenner days, this is a worthwhile read.
What I found most interesting is that Munson, a man who didn't talk to the press much and wasn't really one for autographs, was such a beloved figure in New York. It tells you a lot about the way he played the game. You'll get a great sense of what kind of player and person Munson was from Appel's new biography.
