The United States, with its activities through the Manhattan Project in WW2, produced the first nuclear weapons. There were thousands of people on this project, from my grandfather working as a general construction worker at Hanford and totally baffled at the tons of perfectly good equipment the army kept dumping in trenches and burying (he was still baffled when I was a kid in the 1960s and it had long been publicly announced that Hanford had made the plutonium for the Nagasaki bomb), to J. R. Oppenheimer and Leslie R. Groves that managed the project.
By the end of Operation Crossroads in the summer of 1946 at Bikini Atoll in the Pacific, we had built a grand total of 9 devices, detonated 5 of them, leaving only 4 in "stockpile".
The US made the first Nuclear Bomb which was an Atomic Bomb. It was used on August 1945 to simply force Japan onto it's knees and surrender to the US.
I think it was Arizona Actually the nuclear bomb called the Manhattan Project was made and tested in New Mexico.

No, the hydrogen fusion bomb was not developed until 1952. The first nuclear weapons were developed and used in combat in 1945.
The atomic bomb was the first nuclear weapon ever made during World war two and it was the first weapon that have been tested before Hiroshima was under attack.

it was first noticed with the nuclear bomb tests.
No one. The first nuclear device was not tested until July of 1945, and the first bomb was not produced (not used) until later that month.
The first was made in the US. The purpose was originally to defend against the possibility of a Nazi bomb. 1945.
Germany has not made a nuclear bomb.
Atom bomb dropped in Japan by the U.S. during WWII
No one person made any nuclear bomb. Different components were/are made by different people, then a team of a dozen or more do final assembly.

Long before the first one was made. That was the purpose of making them: to have a very dangerous bomb (all bombs are dangerous).
