1773-1852
| He was a Scottish chemist. Although he went 
        to graduate school in medicine at the University of Edinburgh in 1799, 
        he was inspired by Joseph Black to take 
        up chemistry. In 1796, he succeeded his brother James as assistant editor 
        of the Supplement to the Third Edition of the Encyclopædia Britannica, 
        contributing the articles "Chemistry", "Mineralogy", 
        and "Vegetable", "Animal" and "dyeing substances". 
        In 1820, he used these articles as the basis of his book System of 
        Chemistry. In 1817, Thomson became regius professor of chemistry 
        at the University of Glasgow in Scotland, and in 1820, he identified a 
        new zeolite mineral, which was named thomsonite in his honor.
