text: Ogston was educated at Eton College and Balliol College, Oxford. Apart from a period as Freedom Research Fellow at the London Hospital, he spent most of his career at Oxford, being appointed Demonstrator (1938) and Reader (1955) in Biochemistry, and Fellow and Tutor in Physical Chemistry at Balliol (1937). In that capacity he had a major influence on other distinguished scientists, such as the Nobel prizewinner Oliver Smithies, who wrote his first paper with him, and Richard Dawkins, who chose to study zoology on his recommendation. In 1959 he took up an appointment as Professor of Physical Biochemistry at the John Curtin School of Medical Research at the Australian National University (ANU), Canberra, where he remained until 1970, when he returned to Oxford as President of Trinity College. On his retirement in 1978, he held visiting fellowships at the Institute for Cancer Research, Philadelphia and the John Curtin School of Medical Research, ANU. Ogston was elected FRS in 1955, and was awarded Lemberg Medal in 1970 and the Davy Medal in 1986.
