In 1942 Einstein contacted Franklin Delano Roosevelt in a letter telling him about the atomic bomb making that was going on in Germany. The concept of building atomic bombs was sparked by that letter. The Manhattan Project started soon after Roosevelt received the letter.
Yes, both.
Atomic Bomb
yes we did
The atomic bomb is too expensive to develop for a city to have them. They are weapons held only by industrialized countries.
Manhattan Project
No, Albert Einstein did not develop the atomic bomb, which was developed by a team of researchers led by J. Robert Oppenheimer. Einstein's theoretical work does provide the basis upon which the bomb was developed.

The Manhattan Project was the secret research program to develop the atom bomb.
The second nation to develop an atomic bomb was the Soviet Union. They successfully tested their first atomic bomb, known as "First Lightning," on August 29, 1949, following the United States, which conducted its first successful test in 1945. The Soviet atomic bomb program was accelerated by espionage efforts that provided them with crucial information from the American Manhattan Project.
