King's College London Department of Physics

Instruction in physics began in 1831 in the form of lectures in natural and experimental philosophy delivered to students in the Senior Department, from 1839 the Department of General Literature and Science and later the Department of Applied Sciences. Natural and experimental divisions were separated in 1834 when Charles Wheatstone was appointed Professor of Experimental Philosophy, a post he occupied until his death in 1875. Classes in natural philosophy were available to Evening Class students and students of the Medical Faculty and Faculty of Engineering, but the Physics Department properly became part of the Faculty of Science in 1893. In 1923 Physics became part of the Faculty of Natural Science, which later formed part of the Faculty of Mathematical and Physical Sciences. This became the School of Physical Sciences and Engineering in 1991. Charles Wheatstone, responsible for pioneering experiments in the fields of electric telegraphy, batteries, harmonics and optics, upon his death bequeathed an extensive collection of scientific instruments and equipment to the College to form the Wheatstone Laboratory, one of the earliest physical laboratories in the country. Other notables include James Clerk Maxwell, pioneer in the study of electromagnetism, who was Professor of Natural Philosophy, 1860-1865; Charles Glover Barkla, Wheatstone Professor of Physics, 1909-1914, who whilst at the University of Edinburgh was awarded the Nobel Prize for Physics in 1917 for work on X-rays; Sir Owen Richardson, Wheatstone Professor of Physics, 1914-1922, awarded a Nobel Prize for Physics in 1928 for prior work on thermionics undertaken at the Cavendish Laboratory, Cambridge; Sir Edward Appleton, Wheatstone Professor of Physics, 1924-1936, who conducted experiments on the interaction of radio waves with the earth's atmosphere at the Strand and at the College's Halley Stewart Laboratories, Hampstead, for which he was subsequently awarded the Nobel Prize for Physics in 1947, whilst employed by the British Government's Department of Scientific and Industrial Research; and Maurice Hugh Frederick Wilkins, Deputy Director of the Medical Research Council Biophysics Research Unit, later the Department of Biophysics, King's College London, 1955, whose work on the structure of the DNA molecule was rewarded with the Nobel Prize for Medicine in 1962.
