Peter Henry Rolfs

Peter Henry Rolfs (1865–1944) was a prominent Florida agronomist in the early 20th century. He directed the Florida Agriculture Experiment Station from 1905 to 1920, and from 1915 to 1920 served as the Dean of the College of Agriculture at the University of Florida. Rolfs then moved to Brazil to found the Universidade Federal de Viçosa in Viçosa, Minas Gerais.
Rolfs was the first to describe a common plant pathogen called Southern Blight, or "Sclerotium rolfsii".
