Jean Beguin

c. 1550-c. 1620

French chemist credited with first mentioning acetone and producing ammonium sulfide. Beguin revealed many mysteries of iatrochemistry through public lectures on the preparation of chemical remedies, and his Tyrocinium chymicum (1610) focused on chemical operations for producing safe medicines. Originally published to obviate the need for dictating lectures to his students, the Tyrocinium was very popular and issued in many editions, remaining the authoritative chemical text until 1695, when Nicolas Lémery's Cours de chymie appeared.
