John Frederick "Wilkie" Wilkinson was a chemist, physician, and pioneering haematologist. He was among the first physicians to experiment with chemotherapy for leukaemia. After secondary education at Arnold School, Wilkinson began in 1913 his study of chemistry at the University of Manchester. In 1916 he joined the Royal Naval Air Service. When WWI ended, Wilkinson resumed his study of chemistry at the University of Manchester, graduating in 1920 BSc with first class honours, in 1921 MSc, and in 1923 PhD. At the University of Manchester he became a demonstrator in crystallography, but then studied medicine, qualifying MB ChB Manch in 1928. Experience of the effects of mustard gas in WWI suggested to him that nitrogen mustards might be effective against bone marrow cancers. With Martin C. G. Israëls, Wilkinson experimented with these agents as therapy for patients with leukaemia. In his youth he was extremely active in The Boy Scouts Association. As a scout he was presented with a badge by Baden-Powell in 1919. In 1924 the increasing demands of his medical career caused him to resign from most of his Scouting commitments, but he continued his involvement with Scouting until his death. He had a large and successful private practice mainly at his rooms at Lorne Street, Manchester, but he sometimes made domicilliary visits in the counties near Manchester. In 1926 George R. Minot and William P. Murphy published their famous paper on feeding raw liver to patients with pernicious anaemia. Wilkinson demonstrated a relation between diet and haematinic activity in tissue by studying stomachs and livers from many species of animals at Manchester's Belle Vue Zoological Gardens and later at Chester Zoo. From 1928 to 1947 at the Manchester Royal Infirmary he was director of the department of clinical investigations and research. In 1931 he graduated with medical research MD from the medical school of the University of Manchester. During the 1930s he once was called upon to delouse the entire ballet company of the Sadler Wells Ballet. From 1934 to 1948 he was a lecturer in systematic medicine at the University of Manchester. Wilkinson was from 1938 to 1946 the director of the Manchester and Salford Blood Transfusion Service and from 1939 to 1946 a regional officer for the North WestBlood Transfusion Service. During the 1940s he, with Frank Fletcher, did pioneering research 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. In 1964 in Bucklow, Cheshire, he married Marion Crossfield, a Major in the Women's Royal Army Corps, but they separated in the 1990s.
