Johann Rudolf Glauber (1604–1670)
Born 1604 CE, died 1670 CE.
Johann Rudolf Glauber (10 March 1604 – 16 March 1670) was a German-Dutch alchemist and chemist. Some historians of science have described him as one of the first chemical engineers. His discovery of sodium sulfate in 1625 led to the compound being named after him: "Glauber's salt".
