Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian and American theoretical physicist and chemical engineer who is known colloquially as "the father of the hydrogen bomb" and one of the creators of the Teller–Ulam design based on Stanisław Ulam's design.
[55] [56] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [57] although only a magnitude 5.1 seismic event was detected at the time of the test, [58] a similar magnitude to the 2013 test of a 6–9 kt (25–38 TJ) atomic bomb. These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was ...
Thomas Powers writes that "of course the bomb designers all knew the truth, and many considered Teller the lowest, most contemptible kind of offender in the world of science, a stealer of credit". [10] Teller became known in the press as the "father of the hydrogen bomb", a title which he did not seek to discourage.
Igor Vasilyevich Kurchatov (Russian: Игорь Васильевич Курчатов; 12 January 1903 – 7 February 1960), was a Soviet physicist who played a central role in organizing and directing the former Soviet program of nuclear weapons, [2] and has been referred to as "father of the Russian atomic bomb".

Hydrogen was a known moderator, so they used water. The results were disappointing. It became apparent that hydrogen slowed neutrons down, but also absorbed them, leaving fewer for the chain reaction. Szilard then suggested Fermi use carbon, in the form of graphite. He felt he would need about 50 tonnes (49 long tons; 55 short tons) (50.8 ...
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961, 4,000 meters over the remote Novaya Zemlya archipelago above the ...
It tested its first atomic bomb at Lop Nur on October 16, 1964 (Project 596); and tested a nuclear missile on October 25, 1966; and tested a thermonuclear (hydrogen) bomb on June 14, 1967. China ultimately conducted a total of 45 nuclear tests ; although the country has never become a signatory to the Limited Test Ban Treaty , it conducted its ...
