Medar Jalot had some learning under the direction of Dr. Ambroise Benoist Gendron of Quebec, Canada. Jalot became a member of a party under the guidance of Henri De Tonty (The Iron Hand) that left Quebec in 1710. They came to Biloxi via the Great Lakes, the Illinois River, the Mississippi River, Lake Manchac and Lake Pontchartrain. Jalot was with the St. Denis expedition to Mexico in 1714 as the valet to St. Denis, and in 1722 was listed in the Natchitoches census. Jalot, although not a doctor by title, served the Natchitoches Post in that capacity because of his skill in treating wounds and body sores. Jalot also had knowledge of many Indian remedies for the sicknesses of the country. It was the custom at this time for Kings to issue certificates to men of the medical profession, designating them as _Docteur du Roi_, Doctor of the King. Doctors who would accept such a commission for frontier duty would receive a year’s salary in advance, clothing, a chest of medicine, an allotment of paper, note books and the personal best wishes of the King. The physician would then in turn be obliged to render his services free to the militia and others connected with the service of a post and the Indians of the surrounding area. The post of his designated-location would place at the doctor’s disposal, an office, lodging and food at the officers’ table. Transportation was obligingly supplied by the King, “a one way ticket.” To the young Doctor who had thus qualified himself this would seem to be a golden opportunity. Dr. Le Beau was the first to arrive at the Natchitoches post. He was the first Doctor to realize that this golden opportunity did not supply medium-of-exchange. The post personnel, their wives and children were exempt from payment for his services. All of the inhabitants and their families supplied the post with food and produce, so they were also exempt as were the Indians. The doctor knew that he would have to wait two years before he would receive his next salary from the King. He could receive payment for his services to the Spanish at Los Adais, but traffic with the Spanish was forbidden. He was soon to realize that the first year’s pay that had been issued would only buy three pairs of pants at Rambin’s Tailor shop ... and that Rambin was making his livelihood by redoing old clothing rather than tailoring new garments. Too, he was duty bound to stay one year in the service to fulfill his obligation to the Crown. By not doing so he was subject to arrest. Needless to say, after his year was up Dr. Le Beau resigned his commission and struck out on his own. In 1727 Dr. Alexander was the next “Docteur du Roi” to arrive in Natchitoches. He was killed in a duel by Captain Jentzen, a Swedish officer in the service of the King of France.
