Career:
Joined the laboratory of Jocelyn Feld Thorpe (FRS 1908) at Imperial College, London, with a brief hiatus during which he conducted research into chemical warfare and the manufacture of poison gas with Cassel Cyanide Company at Glasgow (1918-1920); published fifty-two research papers, was co-author of a 500-page book with Jocelyn Feld Thorpe (1920-1924); Professor of Organic Chemistry at the University of Leeds (1924); carried out a heated debate with Robert Robinson (FRS 1920) on the electronic theoretical approaches to organic reaction mechanisms (1926); returned to London as Professor of Chemistry at University College, in the Department then headed by Professor Frederick George Donnan (FRS 1911) (1930); became Director of the Laboratories upon Donnan’s retirement (1937); presided over various WWII evacuations to University College, Aberystwyth (1939-1945); remained Director until his retirement (1961); died at home from cerebrovascular degeneration and arteriosclerosis.

| OtherInfo | Contributed to the domain of theoretical organic chemistry; the concepts, classifications, and terminology of theoretical organic chemistry, which Ingold introduced and supported, provided a framework of principles that has opened a prospect and a programme for the unlimited unfolding of the theme ‘how organic chemistry works’, and has influenced profoundly the development of chemistry as a whole.
Known for: Organic reaction mechanisms; Cahn–Ingold–Prelog rules; Hughes–Ingold rules; Thorpe-Ingold effect. |
