NEW YORK (AP) — Martin J. Sherwin, a leading scholar of atomic weapons who in “A World Destroyed” challenged support for the U.S. bombing of Japan and spent more than two decades researching the pioneering physicist J. Robert Oppenheimer for the Pulitzer Prize-winning “American Prometheus,” has died.

Sherwin died Wednesday at his home in Washington, D.C., according to his friend Andrew Hartman, a professor of history at Illinois State University. He was 84 and had been battling lung cancer. Kai Bird, a close friend and the co-author of “American Prometheus,” called him “probably the preeminent historian of the nuclear age.”
