Johann Rudolf Glauber

Died 10 Mar 1668 (born 1604).German-Dutch chemist, sometimes called the German Boyle; i.e., the German father of chemistry. Glauber supported himself by selling secret chemicals and medicinals. He prepared hydrochloric acid from common salt and sulphuric acid and pointed out the virtues of the residue, sodium sulphate - sal mirabile, or Glauber's salt. He also noted the formation of nitric acid from potassium nitrate and sulphuric acid. Glauber prepared many substances, made useful observations on dyeing, and described the preparation of tartar emetic. He urged that Germany's natural resources be developed and gave examples of such developments.[EB gives date of death 10 Mar 1668. DSB gives Mar 1670.]
