Stubbins Ffirth (1784–1820) was an American trainee doctor notable for his unusual investigations into the cause of yellow fever. He theorized that the disease was not contagious, believing that the drop in cases during winter showed that it was more likely a result of the heat and stresses of the summer months. While correct in noting that yellow fever was significantly more prevalent in summer, Ffirth's explanation proved to be incorrect. It was a full six decades after his death that a breakthrough would be made, with Cuban scientist Carlos Finlay discovering the link to mosquitoes carrying the disease.
