Ambrose Godfrey-Hanckwitz (1660 - January 15, 1741) was a German apothecary. In 1679, he travelled to London where he worked as an assistant to Robert Boyle, trying to produce phosphorus. Two years of research satisfied Boyle's curiosity, but Godfrey was still interested in phosphorus and Boyle agreed to finance him. Godfrey's business grew along with his reputation, and he took on employees, becoming known for producing the best phosphorus available. He also invented and patented a machine that acted as a fire extinguisher. No artist credited, undated (cropped and cleaned).
