Joseph Priestley

In 1794, Joseph Priestley (1733-1804), chemist and natural philosopher, arrived at New York in the United States, having emigrated from England. Soon thereafter, he settled at Northumberland, Pennsylvania. Although now remembered for his scientific work (including the discovery of oxygen on 1 Aug 1774, and other gases), in his time he became unpopular in England for his political opinions and support of the French Revolution. His home and laboratory were set on fire on 14 Jul 1791, and by 1794 he decided to leave his home country and pursue his scientific studies in America.«
