That depends to some extent on precisely what you mean by "led." Robert Oppenheimer was the scientific head of the project; the military head of the project (and Oppenheimer's clear superior in the organizational chart) was General Leslie Groves.
Under Oppenheimer, the scientists were arranged into various teams, each headed by a different scientist. (At one time, one person was the head of two different teams ... he joked that, since the secrecy rules prevented unauthorized communication between teams, he needed to seek approval in order to talk to himself.)

Franklin Roosevelt was president during the development of the first atomic bomb. Harry Truman was president when the first two were used in warfare.

The Hydrogen Bomb or H-bomb was not developed until the 1950's. It was only exploded during tests on land and in the ocean.
1753
ENIAC was first used in calculations for the hydrogen bomb
June 1967.
What size of Hydrogen Bomb? How many megatons? the biggest size of hydrogen bomb can done ...........
No, the hydrogen fusion bomb was not developed until 1952. The first nuclear weapons were developed and used in combat in 1945.
The first staged hydrogen bomb was developed by a team at Los Alamos, NM in 1952. It was not a practical bomb as it used cryogenic liquid deuterium-tritium and required a refrigeration system larger than itself to keep it cold.The first practical "hydrogen" bomb was developed by a team at Arzamas-16 in the USSR in 1953. It used dry lithium deuteride, however did not use staging like the 1952 US bomb did so its yield was limited. It was likely done mostly for propaganda purposes. In modern terminology it would be considered a dry boosted fission bomb, not a fusion (hydrogen) bomb.The first practical staged hydrogen bomb was developed by a team at Los Alamos, NM in 1954. It used dry lithium deuteride.The second practical staged hydrogen bomb was developed by a team at Arzamas-16 in the USSR in 1955. It used dry lithium deuteride.In the US the key central concepts of the hydrogen bomb were developed by Stanislaw Ulam and Edward Teller, in the USSR the same concepts were developed by Andre Sakharov.
The first hydrogen bomb "Ivy Mike" was tested in 1952.
The United States developed the hydrogen bomb.
By 1953, the United States and the Soviet Union had developed both the atomic bomb and the hydrogen bomb, or H-bomb. So now that that has happened the United States wanted to have more interests in developing a hydrogen bomb and that's how it intensified.
The Hydrogen bomb being harmful to humans should be realtivley self explanatory... making them was to use them as a deterent to the russians or any other nuclear aggressor. hydrogen bombs were not the only kind that were developed. there were others as well.
U.S. development of the hydrogen bomb.
The Hydrogen Bomb or H-bomb was not developed until the 1950's. It was only exploded during tests on land and in the ocean.
The US program began in 1950 and tested its first device in 1952 and tested a deliverable bomb in 1954. The USSR program began in 1950 and tested a deliverable but limited bomb in 1953 and tested a full scale deliverable bomb in 1955.
We developed the first working atomic bomb but, GER. made up the idea.
The first atomic bomb was made in 1945, the first hydrogen bomb was made in 1952.
The first successful hydrogen bomb was detonated (not launched or dropped--it was a 62-ton fixed structure) on November 1, 1952.
