André Michaux letters to André Thouin
Manuscripts
In these letters, which are written to André Thouin, Michaux's friend and chief gardener of the King's Garden (King Louis XV), both Michauxs discuss their trip to America to study its botany. They talk about the trees and plants they see, grow and collect. More specifically, André talks about some local gardens he grew to produce seeds and specimens. Several of the letters include lists of American trees, plants and seeds, some of which were shipped to France (André worries about the shipments getting to France amongst the chaos of the political upheaval). In one letter, André talks about hoping to correct some of Linnaeus' errors and beat any English publication of his findings. In the letter by Thouin, he talks about the political environment in France (at the beginning of the French Revolution). Eight of the letters are written by André Michaux; two by his son François André; one by André Thouin; and one by Andre Claude Limozin. The letters by the Michauxs are written from New York, NY, Charleston, SC and Philadelphia, PA. All of the letters are in French.
