Adelbert von Chamisso (born Louis Charles Adélaïde de Chamisso de Boncourt) was a German poet and naturalist whose family fled the French Revolution to settle in Prussia. Chamisso was an officer in the Prussian army from 1798–1807 and, as a naturalist, participated in two circumnavigations of the Earth, resulting in the book Bemerkungen und Ansichten auf einer Entdeckungsreise, 1821; expanded edition: Reise um die Welt mit der Romanzoffischen Entdeckungs-Expedition, 1836.
