Claude Joseph Geoffroy

Having a considerable knowledge of botany, he devoted himself especially to the study of the essential oils in plants.

The son of Matthieu François Geoffroy and Louise Devaux, he was born in Paris on 8 August 1685.

From 1718 to 1720 he was Garde des marchands-apothicaires in Paris, then later served as inspecteur de pharmacie at the Hôtel-Dieu.

[1] From 1707 to 1751, he published numerous articles in the Histoire et Mémoires de l'Académie royale des sciences.

[1] During 1729 Geoffroy used a method from Wilhelm Homberg “to determine the strength of vinegar by adding small amounts of potassium”, and this went to be the first ever titration recorded.
