Head to Alibris and order an intriguing book. Either:
- "Moe Berg: Athlete, Scholar, Spy", by Louis Kaufman, Barbara Fitzgerald, and Tom Sewell (1974), or
- "The Catcher Was a Spy", Nicholas Dawidoff (1994)
About the catcher on the 1933 pennant winning team, Moe Berg, Princeton graduate, accidental catcher (playing for the White Sox, who had all their catchers hurt, Berg said to the manager, "You've got a catcher sitting right here on the bench". Curious thing: Berg was talking about Ed Sheely, a first baseman who had done some catching in the minors.). Berg spoke several languages, had a law degree from Columbia, and is said to have given signals in Hindu and Yiddish. Berg worked in the OSS -- predecessor to the CIA -- during WW2.
I'm not kidding. As Casey Stengel says, "You can look it up".
