on chemotherapy for leukæmia, Hodgkin's disease, and polycythæmia vera. From 1947 to 1962 Wilkinson was at the University of Manchester a reader in medicine and haematology and at the Manchester Royal Infirmary head of the department of haematology. He was a co-founder, with Leslie John Witts, of the British Society for Haematology. In 1962 Wilkinson retired from the National Health Service, but he continued to treat patients when he was in his nineties. In 1977 in his Samuel Gee lecture, Wilkinson described his extensive collection of antique medicine jars. The collection is now displayed at the Thackray Medical Museum in Leeds. He was a motorist on both roads and race-courses, a keeper of tropical fish, and a collector of antique porcelain (as well as antique medical jars). In 1964 in Bucklow, Cheshire, he married Marion Crossfield (1920–2003), a Major in the Women's Royal Army Corps, but they separated in the 1990s.
