Simon de la Loubère
Simon de la Loubère (21 April 1642 – 26 March 1729) was a French diplomat, writer, mathematician and poet.
Mission to Siam
Simon de la Loubère led an embassy to Siam (modern Thailand) in 1687 (the "La Loubère-Céberet mission").[1]:2 The embassy, composed of five warships, arrived in Bangkok in October 1687 and was received by Ok-khun Chamnan. La Loubère returned to France on board the Gaillard on 3 January 1688, accompanied by the Jesuit Guy Tachard, and a Siamese embassy led by Ok-khun Chamnan.[1]:3
Upon his return, La Loubère wrote a description of his travels, as had been requested by Louis XIV, published under the title Du Royaume de Siam: "It was by the orders, which I had the honours to receive from the King upon leaving for my voyage to Siam, that I observed in that country, as exactly as possible, all that appeared to be the most singular.[2]
French career
La Loubère was elected member of the Académie française (1693–1729), where he received Seat 16, following the 1691 publication of his book Du Royaume de Siam.[1]:59[3]
La Loubère was a friend of the German scientist Gottfried Leibniz, and once wrote that he had "no greater joy than (to discuss) philosophy and mathematics" with him (22 January 1681 correspondence).[2]
Magic square
La Loubère brought to France from his Siamese travels a very simple method for creating n-odd magic squares, known as the "Siamese method" or the "La Loubère method",[4][5][6] which apparently was initially brought from Surat, India by another Frenchman by the name of M. Vincent, who was sailing on the return ship with La Loubère.[7]
Siamese parachute
La Loubère is also famous for making one of the earliest account of a parachute following his embassy to Siam. He reported in his 1691 book that a man would jump from a high place with two large umbrellas to entertain the king of Siam, landing into trees, rooftops, and sometimes rivers.[8][9][10]
