Claude Joseph Geoffroy (8 August 1685, Paris – 9 March 1752, Paris) was the brother of Étienne François Geoffroy. Like his brother, he was an apothecary and chemist. Having a considerable knowledge of botany, he devoted himself especially to the study of the essential oils in plants. From 1707 to 1751, he published numerous articles in the Histoire et Mémoires de l'Académie royale des sciences. 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.
