Richard L. Garwin, physicist.

A polymathic physicist and geopolitical thinker, Dr. Garwin was only 23 when he built the world’s first fusion bomb. He later became a science adviser to many presidents, designed Pentagon weapons and satellite reconnaissance systems, argued for a Soviet-American balance of nuclear terror as the best bet for surviving the Cold War, and championed verifiable nuclear arms control agreements.
While his mentor, the Nobel laureate Enrico Fermi, called him “the only true genius I have ever met,” Dr. Garwin was not the father of the hydrogen bomb. The Hungarian-born physicist Edward Teller and the Polish mathematician Stanislaw Ulam, who developed theories for a bomb, may have greater claims to that sobriquet.
In 1951-52, however, Dr. Garwin, at the time an instructor at the University of Chicago and just a summer consultant at the Los Alamos National Laboratory in New Mexico, designed the actual bomb, using the Teller-Ulam ideas. An experimental device code-named Ivy Mike, it was shipped to the Western Pacific and tested on an atoll in the Marshall Islands.

“The shot was fired almost precisely according to Garwin’s design,” Dr. Teller said in a 1981 statement that acknowledged the crucial role of the young prodigy. Still, that belated recognition got little notice, and Dr. Garwin long remained unknown publicly.
