Peter Claussen

Peter Clausen (approximately 1801–1872), often misspelt as Peter Claussen, and also known as Pedro Claudio Clausen and Pedro Dinamarquez Clausen, was a Danish natural history collector born in Copenhagen, who was known for his work between 1834 and 1843. His birth and death dates are unclear, sometimes recorded as 1804-1855 or as 1801–1872. His botanical collections are present in many European herbaria. He sold animal fossils to the British Museum and the Jardin des Plantes in France. He later had an article about the geology of Minas Gerais published through the L'Académie Royale des Sciences, des Lettres et des Beaux-Arts de Belgique. He worked with Jules Paul Benjamin Delessert. Provided by Wikipedia
