Neither president Roosevelt ordered atomic bombs dropped on anyplace.Teddy Roosevelt died in January 1919 and never heard anything about nuclear weapons.Franklin Roosevelt died in April 1945, he was replaced by Harry Truman who authorized the use of the atomic bombs but did not select the targets they would be use on (he left that decision up to the Army).
The moment Stimson informed him that the project to build atomic bombs existed and that Franklin D. Roosevelt had already issued orders for the Army to plan to use them on Japan, after Truman was sworn in as president following Franklin D. Roosevelt's death. Truman saw no reason to change these plans.
In July 1939 Albert Einstein sent a letter to President Roosevelt informing him of German atomic research and the potential for a bomb. This letter prompted Roosevelt to form a special committee to investigate the military implications of atomic research. This committee worked under the name 'The Manhatten Project' and the chief scientist involved in developing the first atomic bomb was Robert Oppenheimer.
Shortly after President Roosevelt (FDR) passed away, Truman came into office and made this decision.
