Jean-Baptiste Leschenault de La Tour
Leschenault de La Tour was chief botanist on Nicolas Baudin's expedition to Australia between 1800 and 1803. He collected a great many new specimens in 1801 and 1802, though Baudin's journal suggests that he did not work particularly hard; apparently the poorly educated gardener's boy Antoine Guichenot collected more plant specimens than Leschenault did, and gave them more useful labels. In April 1803 he was so ill that he had to be put ashore at Timor. Forced to spend the next three years on Java he used the time to make the first thorough botanical investigation of the island, which had not previously been visited by naturalists except briefly by Carl Peter Thunberg. He arrived back in France in July 1807 with a large collection of plants and birds.
Leschenault's Javanese birds were described by Georges Cuvier.
Following the Napoleonic Wars, in May 1816 Leschenault travelled to India to collect plants and establish a botanical garden at Pondicherry. He was given permission by the British to travel through Madras, Bengal and Ceylon. He sent many of the plants and seeds he discovered to the French island of Réunion to be cultivated. These included two varieties of sugar cane and six varieties of cotton. He returned to France in 1822 and was awarded the Legion d'Honneur.
Less than a year after his return Leschenault travelled to South America, visiting Brazil, Surinam and French Guiana, and introducing tea bushes to Cayenne, the capital of the French colony. He was forced to return home after only eighteen months due to ill health.
Though Leschenault published little, his collections were subsequently used by other French botanists, including Aimé Bonpland, René Louiche Desfontaines, Antoine Laurent de Jussieu, Jacques Labillardière and Étienne Pierre Ventenat.
The plant genus Lechenaultia is also named after him.
