Sir Edward Albert Sharpey-Schafer (1850 –1935) was an English physiologist and Fellow of the Royal Society. Born Edward Schäfer, he studied under the physiologist William Sharpey and became the first Sharpey Scholar in 1873 at University College London (UCL). In 1874 he was appointed Assistant Professor of Practical Physiology at UCL where he went on to become Jodrell Professor. He was elected a Fellow of the Royal Society in 1878 at the age of just 28. Schäfer was appointed Chair of Physiology at the University of Edinburgh in 1899 where he would stay until his retirement. He was one of the nineteen founder members of the Physiological Society in 1876 and he also founded and edited [the Quarterly Journal of] Experimental Physiology from 1908 until 1933. Schäfer was knighted in 1913. He is renowned for his invention of the prone-pressure method or Schäfer method of artificial respiration. He was very active as a facilitator, mentor, coordinator, teacher and organiser through much of his career. He had started as a histologist and always emphasised the importance of structural knowledge. He was the co-discoverer (in 1894, with George Oliver) of adrenaline (as in the adrenal-derived, circulating hormone) and he coined the term ‘endocrine’ as the generic term for such secretions. He intuited (as did a few others, independently) that insulin must exist (i.e. a pancreatic hormone to account for diabetes mellitus) and coined the name (originally as ‘insuline’). (Banting and Best actually discovered what S-S and the others had predicted). Thus, he had a founding role in modern endocrinology. He also did important early work on the localisation of function (e.g. motor centres) to brain regions. After the death of his eldest son, John Sharpey Schafer, and in memory of his late professor William Sharpey, he changed his surname to Sharpey-Schafer in 1918. Sir Edward Albert Sharpey-Schafer died on 29 March 1935 aged 84. Funded by bequests from Sir Edward Sharpey-Schafer (1850–1935) and his daughter Miss GM Sharpey-Schafer and in memory of Sir Edward and his grandson Professor EP Sharpey-Schafer, The Physiological Society established the Sharpey-Schafer Prize Lecture. This is a triennial lecture given alternately by an established physiologist (preferably but not necessarily from abroad) and a young physiologist chosen by The Society.
