Pyke was born at Gloucester Terrace, Paddington, London, the son of Clara Hannah Lewis and Robert Bond Pyke, manager of a wholesale confectionery business. He went to St. Paul's School, Barnes, London, where he found he had a "certain bounciness combined with a lack of self-consciousness."[1]
He worked briefly for an insurance company before emigrating to Canada to attend Macdonald College, McGill University, Montreal, studying agriculture, gaining a BSc in 1933. During summers there, he worked as a farm labourer. He remained in Canada for seven years.[2]
On 23 August 1937 he married Dorothea Mina Vaughan (1907–86), an accountant. They had a daughter and a son.[2]
Wartime scientific career
In 1941 Pyke joined Professor Drummond at the Ministry of Food where Drummond was scientific adviser. They studied the nutritional effects of food restrictions due to wartime shortages. He lectured on practical nutrition for those working in institutions that provided food: these lectures were published by H.M. Stationery Office under the title The Manual of Nutrition (1945) [the revised 12th edition is still in print, published by the Food Standards Agency]. He supported the idea of using rose hip syrup to replace imported orange juice. He was a scientific adviser to the Allied Commission for Austria in 1945–6, after which he worked as Principal Scientific officer at the Ministry of Food (1946–48), continuing to work on institutional diets and nutritional education.[2][3]
Later scientific career
He joined The Distillers Company in 1949 as the deputy manager of the yeast research division at Glenochil Research Station, Clackmannanshire. In 1955 he became manager, retiring in 1973.[4][3]
He became a council member of the British Association for the Advancement of Science in 1968, then secretary, and finally chairman in 1973, a position he held until 1977.
He claimed that food manufacturers provided a social service and defended them against accusations of providing unhealthy products.[5][3]
