The American atomic bomb was built mostly by German Jewish scientists who escaped Nazi oppression to America. According to Time magazine, the Nazis would've had their nuke built before America if they hadn't lost the war.
The American and British government and military leaders never planned for using the first atomic bomb on Nazi Germany, but they did worry that Germany might have an advanced nuclear program, which they did. By the time Germany surrendered in May 1945, the American atomic bomb program still hadn't produced the first bomb.
J. Robert Oppenheimer was the "science guy" at the Manhattan Project.
This is a very long process, and we give rather short answers. You need to research the Manhattan Project. That was the code name for the US Atomic Weapons program. There were 2 different types of atomic weapons built, and they were completed in 1945.
