At Columbia in 1931, his work separating isotopes led to the discovery of deuterium. During World War II he turned that skill toward uranium enrichment, heading the Columbia team that developed gaseous diffusion—the sole method used in the early postwar period. At the University of Chicago after the war, he speculated that Earth's early atmosphere was ammonia, methane, and hydrogen; his student Stan…
