Louis Nicolas Vauquelin was director of the School from its foundation in 1803 until his death in 1829. He also held professorships at the School of Mines, at the Polytechnic School, and with the Faculty of Medicine. He began his career as a boy in the laboratory of a pharmacist at Rouen, and later got a situation with M. Cheradame, a pharmacist in Paris. Cheradame was related to Fourcroy, to whom he introduced his pupil. Fourcroy paid him £12 a year with board and lodging, but he proved such an indefatigable worker that in no long time he became the colleague, the friend, and the indispensable substitute of his master in his analyses as well as in his lectures. He is cited as the discoverer of chromium, of glucinium, and of several animal products; but his most important work was a series of chemical investigations on belladonna, cinchona, ipecacuanha, and other drugs, which it is recognised opened the way for the definite separation of some of the most valuable of the alkaloids accomplished afterwards by Pelletier, Caventou, Robiquet, and others. Vauquelin published more than 250 scientific articles.

Antoine Augustin Parmentier (born 1737, died 1813), after serving an apprenticeship with a pharmacist at Montpellier, joined the pharmaceutical service in the army, and distinguished himself in the war in Germany, especially in the course of an epidemic by which the French soldiers suffered seriously. He was taken prisoner five times, and at one period had to support himself almost entirely on potatoes. On the last occasion he obtained employment with a Frankfort chemist named Meyer, who would have gladly kept him with him. But Parmentier preferred to return to his own country, and obtained an appointment in the pharmacy of the Hotel des Invalides, rising to the post of chief apothecary there in a few years. A prize offered by the Academy of Besançon for the best means of averting the calamities of famine was won by him in 1771, his German experience being utilised in his advocacy of the cultivation of potatoes. These tubers, though they had been widely cultivated in France in the sixteenth century, had gone entirely out of favour, and were at that time only given to cattle. The people had come to believe that they occasioned leprosy and various fevers. Parmentier worked with rare perseverance to combat this prejudice. He cultivated potatoes on an apparently hopeless piece of land which the Government placed at his disposal, and when the flowers appeared he made a bouquet of them and presented it to Louis XVI, who wore the blossoms in his button-hole. His triumph was complete, for very soon the potato was again cultivated all through France. The royalist favour that he had enjoyed put him in some danger during the Revolution; but in the latter days of the Convention, which had deprived him of his official position and salary, he was employed to organise the pharmaceutical service of the army. He also invented a syrup of grapes which he proposed to the Minister of War as a substitute for sugar during the continental blockade.
The medallions, in the order in which they appear on the façade of the École de Pharmacie, represent the following French and foreign pharmacists:—
Antoine Jerome Balard, the discoverer of bromine (born 1802, died 1876), was a native of Montpellier, where he qualified as a pharmacist and commenced business. As a student he had worked with the salts deposited from a salt marsh in the neighbourhood, and had been struck with a coloration which certain tests gave with a solution of sulphate of soda obtained from the marsh. Pursuing his experiments, he arrived at the discovery of bromine, the element which formed the link between chlorine and iodine. This early success won for him a medal from the Royal Society of London and a professorship of chemistry at Montpellier, and subsequently raised him to high scientific positions in Paris. Balard did much more scientific work, among which was the elaboration of a process for the production of potash salts from salt marshes. He had worked at this for some twenty years, and had taken patents for his methods, when the announcement of the discovery of the potash deposits at Stassfurt effectually destroyed all his hope of commercial success.
Joseph Bienaimé Caventou (born at St. Omer 1795, died 1877) carried on for many years an important pharmaceutical business in Paris. His fame rests on his association with Pelletier in the discovery of quinine in 1820.
Joseph Pelletier (born 1788, died 1842) was the son of a Paris pharmacist, and was one of the most brilliant workers in pharmacy known to us. He is best known for his isolation of quinine. Either alone, or in association with others, he investigated the nature of ipecacuanha, nux vomica, colchicum, cevadilla, hellebore, pepper, opium, and other drugs, and a long series of alkaloids is credited to him. He also contributed valuable researches on cochineal, santal, turmeric, and other colouring materials. To him and his associate, Caventou, the Institute awarded the Prix Monthyon of 10,000 francs for their discovery of quinine, and this was the only reward they obtained for their cinchona researches, for they took out no patents.
