biography: Chemist and physiologist, born in Horton, Gloucestershire, SWC England, UK. He studied at Edinburgh University, and practised in London from 1812. He is noteworthy for his discovery of the presence of hydrochloric acid in the stomach, and for his ‘Hypothesis’ (1815), which stated that the relative atomic masses of all elements are whole number multiples of that of hydrogen, which is a primary substance. Although later shown to be incorrect, modern science does accept the hydrogen nucleus (the proton) as a kind of primary substance.
