George Samuel Perrottet (23 February 1790 – 13 January 1870, Pondicherry), also known as Georges Guerrard-Samuel Perrottet,[1] was a botanist and horticulturalist from Praz, in the commune of Vully-le-Bas, today Mont-Vully, Switzerland. After expeditions in Africa and Southeast Asia where he collected plant and animal specimens, he worked in French Pondicherry, India, where he established a botanical garden. He took a special interest in plants of economic importance and was involved in the activities of acclimatisation societies in the various colonies of France. Many of his zoological specimens, sent to museums in France, were examined by other naturalists and named after him.
