Biographical History

Karl Andreas Geyer was born in Dresden, Germany, November 30, 1809. He worked as an apprentice at a garden in Zabelitz, later as assistant at a Botanic Garden in Dresden. He came to the United States in 1835, three years later joining Joseph N. Nicollet’s expedition up the Mississippi and Missouri River. Geyer went on to collect across much of the central United States including with botanist George Engelmann along the Mississippi and Illinois River as well as with explorer William Drummond Stewart in Nebraska and Wyoming. He also collected in Idaho and Washington. Geyer eventually returned to Europe in 1845, and settled in Meissen, Germany, where he married and established a nursery. He edited the horticultural journal Die Cronik des Gartenwesens. A portion of Geyer’s botanical collection resides at Royal Botanic Gardens, Kew.
