Barnard, George Alfred (1915^2002): Born in Walthamstow in the east of London, Barnard achieved a scholarship to St. John's College, Cambridge, from where he graduated in the mathematics in 1936. For the subsequent three years he studied mathematical logic at Princeton, New Jersey, and then in 1940 joined an engineering ?rm, named as Plessey. After three years acting as a mathematical consultant for the engineers, Barnard joined the Ministry of Supply and it was here that his interest in statistics evolved. In 1945 he went to the Imperial College London, and then in 1966 he moved to the chair in the newly created University of Essex, where he remained until his retirement in 1975. Barnard made major and significant contributions to the several fundamental areas of inference, including likelihood and 2 × 2 tables. He was made The President of the Royal Statistical Society in 1971-2 and also was given the Society's Guy medal in gold. He died in the Bright ling sea, Essex, on 30 July 2002.
