From 1947, as an ICI Research Fellow, Cosslett worked with William Lawrence Bragg at the Cavendish Laboratory, Cambridge University on the electron microscope and founded the Electron Microscopy Department. He also developed improved x-ray machines.
Honors and awards
Cosslett was elected Fellow of the Royal Society in 1972 and won the Royal Medal in 1979 "In recognition of his outstanding contributions to the design and development of the X-ray microscope, the scanning electron microprobe analyser, the high voltage and ultrahigh resolution (2.5A) electron microscopes and their applications in many disciplines."
He was elected president of the Royal Microscopical Society. and was also instrumental in the creation of International Federation of Societies for Electron Microscopy where he was president from 1970 till 1973.
Personal life
Cosslett had married firstly, in 1936, Rosemary Wilson. During the Second World War, Cosslett provided accommodation for refugee scientists at his flat in Hampstead; thus he met Viennese physicist and microscopist Dr Anna Joanna Wischin (1912–1969) whom Cosslett married in 1940 following his divorce from his first wife. Dr Anna Cosslett also worked at the Cavendish Laboratory. He had a son and a daughter from his second marriage.
