J. W. Legge



John Williamson Legge, better known as Jack Legge (3 April 1917 – 29 October 1996), was an Australian biochemist and communist activist. He is best known for his work testing the effects of mustard gas on Australian troops in tropical conditions during World War II.

History
Legge was born at 18 Beaver Street, East Malvern, Victoria the only child of Congregationalist Rev. George Alexander Williamson Legge (1871 – 22 March 1931) and his second wife Florence Legge, née Laver. He was educated at Geelong College and the University of Melbourne, completing his BSc in absentia in 1938.

Shortly before his graduation, he moved to Sydney to work under Dr "Rudi" Lemberg at the Kolling Institute of Medical Research under a grant from the National Health and Medical Research Council (NH&MRC) studying blood pigment metabolism. Their research resulted in their successful book Hematin Compounds and Bile Pigments being published in 1949.

As early as 1939, Legge was thinking seriously about air-raid precautions, including gas attacks on civilians. In July 1939, he became a founding member of the Australian Association of Scientific Workers. This organisation, formed as a grassroots and industry-focussed alternative to the existing scientific societies, was disbanded in 1949 as a result of political attacks founded in Cold War hysteria. From 1942 to 1946 Legge worked with the Australian Chemical Warfare Research & Experimental Section (later known as the 1st Field Trials Company, Royal Australian Engineers) on research into protective clothing and other aspects of defence against chemical warfare attacks in tropical conditions. This included physiological research on the effects of mustard gas trials on Australian Defence Force volunteers in Townsville, North Brook Island, Proserpine and Mission Beach. Legge and a fellow biochemist (later Prof. Sir) Hugh Ennor designed and oversaw the construction of a 100 m3 stainless steel temperature-controlled gas chamber. Legge described the work as "grisly" but necessary, because it was known that the Japanese armed forces had large stocks of this gas, and that tropical heat and humidity would render it more effective in use than it had been on the Western Front in World War I. In later life he supported claims for compensation by those volunteers who suffered chronic illness that may been a result of those trials. This included the official photographer of the project, who developed severe chronic respiratory problems owing to his occupational exposure to the gas, from which he later died. The 1989 documentary film Keen as Mustard documented these events.

The University of Melbourne
Legge was granted a fellowship which enabled him to spend two years in England, working at the Molteno Institute, Cambridge University under Professor David Keilin. He moved his family to the Melbourne suburb of Greensborough when he was hired by Victor Trikojus as a biochemistry lecturer at the University of Melbourne in 1950. Trikojus, a conservative, maintained his public support of Legge, a communist, throughout his tenure and especially before his appearance before the Petrov Royal Commission. In 1960 his area of research was the biochemistry of the hormone secretin, despite it being "outside his prime interest" which was the metabolism of bacterial and animal cells. He was described by a former student as "a brilliant man with a very agile mind", but that Legge didn't do much research, being so involved in activism for the Communist Party. Despite earning the esteem of his colleagues, his obvious passion for teaching, and his flair for research, the highest position Legge achieved was that of senior lecturer. It has been noted that, as for other Australian communists during the cold war, Legge's political beliefs may have adversely affected his career. As one academic noted: "Jack Legge... [was] one of the very few of his academic contemporaries never to be promoted to a professorship." Legge retired from the university in 1981.

Politics
Legge joined the Communist Party of Australia (CPA) in 1935 or 1936 and helped distribute the Tribune at a time when the newspaper was banned. In 1946 he was contributing articles on science for the Tribune. He was, in September 1949, a charter member of the Australian Peace Council. On 29th October 1954, he appeared before the Royal Commission on Espionage in relation to these and other activities he carried out on behalf of the Communist party. He was extensively questioned about an alleged 1950 meeting with his cousin George Legge who worked for the Department of External Affairs in Canberra at the time. In particular, he was questioned about allegations made that his name was written in notes allegedly made by a former MVD chief named Sadovnikov. These notes were turned over to the Australian Government by Petrov following his defection. These notes alleged that Legge and his friend Walter Seddon Clayton, also a CPA member, had a meeting in 1950 with George Legge to ask his advice on foreign affairs so as to aid the development of the Australian Communist Party's foreign policies. George Legge told his superiors about this meeting, after which he was transferred to a minor posting, from which he resigned. Jack Legge denied the meeting had ever taken place, and denied he had been involved in espionage or any wrongdoing.

Legge wrote for the Communist Party of Australia magazine Australian Left Review, including the articles: A passionate educator, he continued to be a science communicator after his retirement, using his radio program "CR Science" to inform the public about scientific breakthroughs in the mid-1980s.

Family
Legge married fellow Communist Party of Australia member Gertrude Avon Guiterman on 29 June 1940. They had four boys, including educator, author and activist John Michael Legge. Legge's papers are held at the University of Melbourne Archives. Files relating to his appearance before the Royal Commission are held at the National Archives of Australia.
