Dr. Edgar T. Wherry (1885-1982) was a mineralogist and botanist who specialized in ferns. He was a professor of botany at the University of Pennsylvania from 1930-1955, and in 1932 he was appointed ecologist to the Morris Arboretum. The Dr. Edgar T. Wherry botanical lantern slides, circa 1920s-1976, consist of dozens of lantern slides (primarily hand-painted photographs) created by Dr. Edgar T. Wherry depicting botanical specimens, some from the Morris Arboretum and others from locations throughout the world. There is also one slide script from a 1976 lecture on Phlox in the collection.
