John Stenhouse FRS FRSE FIC FCS (21 October 1809 – 31 December 1880) was a British chemist.

However, in February 1851 he was appointed Lecturer on Chemistry to the medical school at St Bartholomew's Hospital in London.

[8]) In 1857 Stenhouse suffered a stroke,[9] which left him partially paralyzed and forced him to resign his position.

In June of that year he returned to England and opened a laboratory in an outbuilding of an abandoned factory on Rodney Street, King's Cross, London; there he supported himself by assaying, consulting, and performing other contract work.

[11] These assistants included Raphael Meldola (1849-1915), who would become an eminent organic chemist, and Charles E. Groves (1841-1920), who co-authored of many of Stenhouse's papers, which ultimately numbered in excess of 100.

He also discovered lead trinitro-orcinate now commonly used in non-corrosive priming compositions, even though this application was only developed decades after his death.
