Jean Beguin

From Wikipedia

Jean Beguin (1550–1620) was an iatrochemist noted for his 1610 Tyrocinium Chymicum (Begin Chemistry) ( Digital edition), which many consider to be one of the first chemistry textbooks. In the 1615 edition of his textbook, Beguin made the first-ever chemical equation or rudimentary reaction diagrams, showing the results of reactions in which there are two or more reagents. [1] Modern rendering of this famous diagram, detailing the reaction of corrosive sublimate (HgCl2) with sulfide of antimony (Sb2S3), is shown below: [2]
