J. F. C. (Justus Friedrich Carl) Hecker (1795–1850) has one book in the BigBookHub catalogue: The Epidemics of the Middle Ages.
A mid-19th-century history of three medieval epidemics: the Black Death, the Dancing Mania and the Sweating Sickness. It opens with the plague's symptoms and the fear it caused, and urges historical study of epidemics.
