Sir George Lindor Brown, commonly referred to as Sir Lindor Brown, or to colleagues simply as ‘GL’ (1903 –1971) was an English Physiologist and Fellow of the Royal Society. Brown attended the University of Manchester on a scholarship to study medicine, where Nobel Prize winner A V Hill was the professor of physiology. He completed his BSc and MSc in 1924 and 1925 respectively, finally qualifying in medicine in 1928 and joined the university as a lecturer. During his time at the University of Manchester, Brown won both the Platt Physiological Scholarship and the Bradley Prize and Medal for operative surgery. In 1934 he accepted a post at the National Institute for Medical Research in Hampstead, offered by Sir Henry Dale, where he worked with Sir John Gaddum and W S Feldberg, helping to establish the cholinergic theory of chemical transmission. Brown left the Institute in 1949 to become the Jodrell Chair of Physiology at University College London to strengthen the Department and help underpin the creation of the Biophysics departments under Sir Bernard Katz (from 1952). He served on various committees for the Royal Society, and became Biological Secretary from 1955-1963. He was knighted in 1957. In 1960, Brown moved to the University of Oxford, taking the post of Waynflete Chair of Physiology and becoming a Fellow of Magdalen until 1967 when he was elected Principal of Hertford College Oxford. Sir George Lindor Brown passed away on 22 February 1971 aged 68. In 1975 The Physiological Society established the GL Brown Prize Lecture in his memory, this is an annual series of peripatetic lectures aimed at a younger audience in order to stimulate an interest in physiology.
