Henry Stephen OBE, DSc.[1] (10 July 1889 – 6 July 1965) was an English chemist known for inventing the Stephen Reaction, a method of deriving aldehydes (R-CHO) from nitriles (R-CN).
Leonard Henry Nelson Stephen, later known as Henry Stephen, was born at 11 Dalton Terrace, Manchester, son of John Stephen, printer, and Mary Eliza (née Owen).
He studied chemistry under Dr Chaim Weizmann at Victoria University of Manchester.[2] Along with Dr. J. E. Myers, Stephen contributed to the British World War I effort by developing a process to make mustard gas that was more rapid than the process being used by the Germans. In 1920, both received the OBE award for their work.[3][1] He received his DSc degree from Victoria University of Manchester in 1920 and continued on as a senior lecturer. Dr. HENRY STEPHEN, O.B.E., Senior Lecturer in Chemistry in the Victoria University of Manchester; was elected to Ordinary Membership of the Society General Meeting, 19 October 1920.[4] In 1925 he published A New Synthesis of Aldehydes, known as the Stephen Reaction. From 1926 to 1954, Stephen was professor of chemistry at the University of the Witwatersrand in Johannesburg.[5]
