Paul Jacques Malouin

Paul Jacques Malouin (27 June 1701 – 3 January 1778) was a French physician and chemist.

Career Born in Caen, Malouin graduated in medicine in 1730 against the wishes of his father (a legal official from Caen) who had sent him to Paris to study law. He settled in Paris in 1734 and opened a medical practice which attracted patients from the aristocracy and royal family.

With the help of Fontenelle, a distant relation, he entered the French Academy of Sciences in 1742 where his particular research interest was the application of chemistry to medicine. In 1745 he was appointed professor of chemistry at the Jardin du Roi.

For nine consecutive years he studied the epidemics raging in Paris and recorded the results of his research in his Mémoires published by the Academy of Sciences between 1746 and 1754, linking epidemic diseases to air temperature.

In 1753 Malouin began a formal association with the royal court when he bought from Lassone the position of médecin de la reine (physician to the queen) for the sum of 22,000 livres; he was subsequently made physician to the Dauphine in 1770. Thereafter he spent increasing amounts of time at court, being granted an apartment in the Louvre and having rooms at Versailles.

In 1742 Malouin described, in a presentation to the Royal Academy, a method of coating iron by dipping it in molten zinc (i.e. hot-dip galvanizing).

In 1753 he became a Fellow of the Royal Society and in 1767 was made a professor at the Collège de France. In 1776 he was appointed professor at the Royal College where he occupied the Chair of Medicine until his death in January 1778 in Versailles. It was recorded that at the time of his death his fortune amounted to 132,775 livres, 110,000 of which was in the form of state bonds. Another 18,500 was invested in the Compagnie des Indes; his personal possessions were valued at 3,275 livres.
