The British physicist Professor Sir John Enderby, a neutron-science pioneer, has died aged 90. He developed innovative ways of using neutrons to study matter at the microscopic level. Enderby had a long association with Institute of Physics Publishing (IOPP) in Bristol, where he served for many years as scientific advisor. He was also president of the Institute of Physics (IOP). He worked at the universities of Huddersfield, Sheffield and Leicester, before accepting a chair at the University of Bristol in 1976. In 1985–1988 Enderby took leave from Bristol to serve as the British directeur-adjoint of the Institut Laue-Langevin in Grenoble, France – which is a leading international centre for neutron science.
He has also served science with distinction through work with many scientific organisations including the Royal Society; the Particle Physics and Astronomy Research Council as a founder member; and, in particular, the Institute of Physics where he has served as President and Institute of Physics Publishing where he was currently Chief Scientist. One of the most significant achievements in liquid-state physics that occurred in the 20th century resulted due his collaboration in the 1960s with Peter Egelstaff. Enderby was awarded the Guthrie Medal of the Institute of Physics. His contributions have been recognised by the award of a CBE in 1997 and a Knighthood for services to Science and Technology in 2004.
