Robert Ditchburn (physicist)

Robert William Ditchburn (14 January 1903 – 8 April 1987) was an English physicist whose career started at Trinity College Dublin (TCD), where he was appointed Erasmus Smith's Professor of Natural and Experimental Philosophy in 1929, and ended at the University of Reading, where he worked hard to build up the physics department.[1]

Life and career

Ditchburn was born in Waterloo, Lancashire, England, and was educated first at Liverpool University, taking a physics degree there in 1922. He then went to Trinity College, Cambridge, earning BA (1924) and a PhD (1928) for research done under J. J. Thomson at the Cavendish Laboratory.[2]

He successfully competed for a Fellowship at TCD in 1928, and the following year moved to Ireland to become Erasmus Smith's Professor of Natural and Experimental Philosophy. Apart from a few years back in England at the Admiralty Research Laboratory in Teddington during WWII, he remained in Dublin until 1946. He then became professor and head of the department of physics at Reading University, where he remained until 1968. While there, he focussed on building up the department, and set up the J.J. Thomson Physical Laboratory. He authored the book Light (Interscience Publishers, Inc, 1953).[3] His own research included work on photoionization, the optical properties of solids and the effects of eye movements on visual perception, in particular methods for stabilizing retinal images.[4]

He was very active in retirement, both as a consultant for the diamond industry, and working for nuclear disarmament in Pugwash movement.[1] He published the book Eye Movements and Visual Perception (Clarendon Press, 1973) and in 1983 he was awarded the C. E. K. Mees Medal by The Optical Society[5] “for his lengthy career in many disciplines of optics and for his enrichment of optical knowledge”.[6] In 1960 he got the Thomas Young Orator Prize.[3]
