Christophle Glaser was born in Basel in Switzerland. He was apothecary of the King’s brother and became demonstrator of chemistry at the King’s Gardens in Paris. He had a bad reputation reported by Fontenelle or by the Marchioness of Sévigné. He had also been suspected during the inquiry concerning the Brinvilliers’ murders. He was also known as the author of a book of chemistry, entitled Traité de la Chymie, that had been translated into German or English. He received Lemery in his laboratory. Fontenelle reported that Lémery left Glaser very quickly to go to Montpellier, but he is supposed to have stayed for a longer time with him. Lemery and Glaser had the same opinion on many subjects and their books were similar on many points. It is then established that Glaser was really one of Lemery’s master.
