Living with his family in Winchester since 1957, Allan Cormack dies of cancer on 07. May 1998.

For the development of computer assisted tomography Allan Cormack is awarded the 1979 Nobel Prize in Physiology or Medicine along with Godfrey Hounsfield. They meet for the first time at the ceremony at Stockholm. Sensational is the fact that neither Cormack nor Hounsfield gained a doctorate or comparable degree and they both were not well-know at this time.

Allan Cormack earns a Masters degree in Crystallography in 1945.

Allan Cormack is offered a position at Tufts University in Massachusetts in 1957. He moves to the United States and works in various positions at the Tufts University until his death in 1998. He is the Chairman of the Physics Department from 1968 to 1976. His main areas of research are nuclear and particle physics and x-ray technology.

Allan McLeod Cormack is born as last of three children to his Scottish parents George and Amelia McLeod Cormack in Johannesburg, South Africa.

Allan Cormack spends his sabbatical year at Harvard University, United States, where he investigates on nucleon-nucleon scattering.

Allan Cormack and the American physics student Barbara Seavey get married in 1950 after they met at a lecture about quantum mechanics in Cambridge. They have two daughters and one son.

At first Allan Cormack starts to study electrical engineering like his father and brother at the University of Cape Town. In the course of time he turns to physics and gains his Bachelor´s degree in 1944.

Allan Cormack develops studies about the x-ray absorption of human tissues from 1957 until 1963. He postulates that even small differences in absorption are important. Thereby he lays the groundwork for CAT or CT scans. He publishes his results in 1963 and 1964, but does not receive a lot of attention until Godfrey Hounsfield builds the first CT scanner in 1972, based on Cormack's research.

Allan Cormack is offered a lectureship at the Physics Department at Cape Town, so he returns to Cape Town in 1950 and cancels his research of He6.

After Allan Cormack´s father died in 1936, his family moves to Cape Town. There he visits the Rondebosch Boys High School, where he becomes interested in various fields, like acting, tennis, debating and astronomy.

Allan Cormack works as a Research Student at St John´s College in Cambridge, where he investigates the field of He6 at the Cavendish Laboratory.
