Born in Metz, he wrote the libretto for Gluck's opera Echo et Narcisse and with François-Louis Gand Le Bland Du Roullet co-wrote the libretto for Salieri's Les Danaïdes.
[1] Tschudi contributed many articles on horticulture and natural history to the supplementary volumes of the Encyclopédie.
In a 1790 letter to Charles-Joseph Panckoucke, Lamarck noted that the articles written by Tschudi "contain observations, even in great numbers, which I have used to advantage and which I shall not ignore.
"[2] In a 1777 article in the Encyclopédie that influenced Lamarck, he analysed the effect of climate and soil on transplants.
According to science historian Richard W. Burkhardt: Tschoudi observed that a plant's habitude had to be altered gradually if transplantation were to be successful.
