Johann Rudolf Glauber (1604-1668).

§ 58. Johann Rudolf Glauber was born at Karlstadt in 1604. Of his life little is known. He appears to have travelled about Germany a good deal, afterwards visiting Amsterdam, where he died in 1668. He was of a very patriotic nature, and a most ardent investigator in the realm of Chemistry. He accepted the main iatro-chemical doctrines, but gave most of his attention to applied Chemistry. He enriched the science with many important discoveries; and crystallised sodium sulphate is still called “Glauber’s Salt.” Glauber, himself, attributed remarkable medicinal powers to this compound. He was a firm believer in the claims of Alchemy, and held many fantastic ideas.
