Glauber, Johann Rudolf (1607–1670)




German chemist and physician who prepared a wide variety or organic and inorganic compounds to make use of their (often non-existent) medicinal powers. In preparing hydrochloric acid from sulfuric acid and common salt (see sodium chloride), he found a residue which he claimed to be a cure-all. In fact it was sodium sulfate, a mild laxative which still often called Glauber's salt.
