Description
Framed oval jasperware plaque made c 1860-1868 at the Wedgwood factory at Stoke-on-Trent, Staffordshire, with a cameo portrait of Priestley by John Flaxman. Priestley (1733-1804) discovered various gaseous elements and compounds, and in an experiment in 1774 obtained a gas which he named 'dephlogisticated air'. This was in fact oxygen, although it was not named thus until the French chemist Lavoisier (1743-1794) repeated Priestley's experiment. Priestley had originally trained as a Church minister, but his radical theological and political views made him a controversial preacher. He strongly supported the French Revolution, and after his house in Birmingham was attacked and burnt by a mob in 1791, he left Britain for America in 1794.
