The bomb dropped on Hiroshima from the Enola Gay was known as "Little Boy". The bomb dropped on Nagasaki three days later was significantly larger and was known as "Fat Boy".
The Nagasaki bomb was a plutonium implosion device as exploded in New Mexico at the Trinity site in July 1945. Usually called "Fat Man" because of its rotund shape. For various reasons "Little Boy" though of lower yield was more devastating to human life in Hiroshima.
