Glauber
Glauber, Johann Rudolf (16387-68), the discoverer of Glauber's salt, was born at Karlstadt, Franconia. He lived at different times in Vienna, Frankfort, and Cologne, but finally settled at Amsterdam in 1648, in which year he discovered hydrochloric acid. Though an alchemist, cherishing the dream of the philosopher's stone, he rendered many services to chemical science. An English translation of his works was printed in 1689. [Glauber's Salts.]
