Dr. Stafford Warren was a radiologist and pioneered nuclear medicine. In fact, he invented the mammogram. He was present at the Trinity test where he was responsible for safety, he was sent to Japan after the bombing of Hiroshima and Nagasaki to see what effects the radiation might have on American soldiers, and later he became the first dean of the UCLA medical school. He was THE expert on radiology at the time. This guy was a GENIUS... and apparently an amazing fish catcher.
