 In 1908 he moved to the University of Sheffield to a full-time research appointment, and in 1913 applied for and was awarded the chair of organic chemistry at Imperial College, a post he was to hold until 1939.The previous incumbent was Thomas Edward Thorpe - although the two were not related, his father was a close friend of T. E. Thorpe and it was the latter who persuaded him to switch from engineering to chemistry in his undergraduate career.Although Ingold’s obituary [1] gives a good account of Thorpe’s scientific work it lacks references; Patrick Linstead [3] does give some references and on that account is the better source for Thorpe’s chemical research career.
