Dorothy Mabel Reed Mendenhall (September 22, 1874–July 31, 1964) was a prominent pediatric physician specializing in cellular pathology. In 1901, she discovered that Hodgkin's disease was not a form of tuberculosis, by noticing the presence of a special cell, the Reed-Sternberg cell which bears her name. Dorothy was one of the first women to graduate from Johns Hopkins School of Medicine. She was also one of the first professionally trained female physicians of the late 19th and early 20th centuries.

Dr. Mendenhall lived in Tryon for a time.
