Glauber, Johann Rudolf (1604-1668), a German chemist. Glauber was the first to describe clearly the preparation of hydrochloric acid. He discovered sodium sulfate, which is commonly known today as Glauber's salt. Glauber found it had laxative properties and attributed to it remarkable healing powers. Glauber's salt is still sometimes used as a mild laxative, and also has industrial uses, chiefly in the manufacture of glass.
The man who had some theories about relativity was also an eccentric who gleefully eschewed socks, dodged German military service and spurned social conventions.
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
