Moe Berg—the major league baseball player, OSS operative and legendary linguist—was one of the most remarkable secret agents ever deployed by the US. Whether authorized by the government as an atomic spy or choosing to surreptitiously film Tokyo of his own volition, Berg relished and accomplished his espionage missions, yet he died penniless and with little acclaim. Nicholas Dawidoff brought Moe Berg’s achievements to light in his best-selling 1994 book The Catcher Was a Spy. In honor of the Pennant Race, Dawidoff will share his latest thoughts on the only Major League baseball player to have his card on display at CIA headquarters.
