Allan MacLeod Cormack

Allan MacLeod Cormack (February 23, 1924 – May 7, 1998) was a South African and American physicist, academic, and Nobel laureate. He was Professor of Physics at Tufts University and won the 1979 Nobel Prize in Physiology or Medicine (along with Godfrey Hounsfield) for his work on X-ray computed tomography (CT), a significant and unusual achievement since Cormack did not hold a doctoral degree in any scientific field.
