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:--
