Pehr Kalm (6 March 1716 – 16 November 1779), also known as Peter Kalm, was a Finnish explorer, botanist, naturalist, and agricultural economist. He was one of the most important apostles of Carl Linnaeus. Kalm wrote an account of his travels that was translated into numerous European languages; a 20th-century translation remains in print in English as Peter Kalm's Travels in North America: The English Version of 1770, translated by Swedish-American scholar Adolph B. Benson.
