    Obituaries 2000S

    OBITUARIES 61 OBITUARIES Dr Ron Snaith, 1947-2000 The whole of the chemistry community, as well as Ron' s many friends and colleagues in his other spheres of life, were deeply shocked and saddened by his sudden death on New Year's Day. Ron had been diagnosed with a serious illness some little while before Christmas, and was fighting it with his normal resolve, humour and true 'Yorkshire grit', when he collapsed at home and died in Addenbrookes Hospital a few hours later. Ron leaves his wife, Jane, and two children, Tom and Katie. Jane works in the Department of Genetics, in Cambridge. Tom is in his final year at the University of Durham, reading Chemistry, and Katie is in her second year at the University of Newcastle, Northumbria. The thoughts of all who knew Ron and his family are with them at this very sad time. Ron was born in Kingston-upon-Hull in August 1947, and was fiercely proud of his Yorkshire heritage. Ron studied Chemistry at the University of Durham between 1965-1971, graduating with a 1st Class Honours Degree in 1968, and then going on to read for a PhD, in Pure Science, under the supervision of Professor Ken Wade, FRS. His PhD was in the general area of Main Group Co-ordination Chemistry with particular reference to the investigation of the nature of covalent bonding between organo-nitrogen ligands and metals and semi-metals. Once his thesis was completed Ron then embarked on a career in school teaching. He took a PGCE in the Department of Education at Durham, and then taught at the Durham Johnston Comprehensive School between 1972 and 1979, where he soon became Head of Chemistry.
