Charles Schweinfurth (April 13, 1890 – November 16, 1970) was an American botanist and plant collector who distinguished himself by his studies on orchids.[1] He predominantly collected species from Peru which he described in his four volume reference work Orchids of Peru (1958). He was a researcher at the Botanical Museum of Harvard University, and director of the Ames Orchid Herbarium where, in 1958, he was succeeded by Leslie Andrew Garay.[2]
