Pehr Kalm (1716-1779), a Swedish-Finnish explorer and botanist, was a student of the great naturalist Carl Linnaeus. In fact, Kalm was one of the many “apostles” of Linnaeus sent out to explore the world, and one of the few who didn’t die in the process. To begin the research that later culminated in Travels into North America, Kalm arrived on the continent in 1748. Based in Philadelphia, he worked and traveled with Benjamin Franklin and John Bartram, among others. In his explorations of Pennsylvania and New Jersey and two journeys north through New York to Montreal and Quebec, Kalm formed impressive specimen collections, which Linnaeus subsequently used in naming 90 species of plants, 60 of them new to science, in his Species plantarum (1753). Among those new species, Linnaeus named the mountain laurel genus Kalmia for his disciple.
