John Bartram, American botanist and explorer (d. 1777)
John Bartram (March 23, 1699 – September 22, 1777) was an early Anglo-American colonial botanist, horticulturist, and explorer, based in Philadelphia, Pennsylvania, for most of his career. Swedish botanist and taxonomist Carl Linnaeus said he was the "greatest natural botanist in the world."Bartram corresponded with and shared North American plants and seeds with a variety of scientists in England and Europe. He started what is known as Bartram's Garden in 1728 at his farm in Kingsessing (now part of Philadelphia). It was considered the first botanic garden in the United States. His sons and descendants operated it until 1850. Still operating in a partnership between the city of Philadelphia and a non-profit foundation, it was designated a National Historic Landmark in 1960.
