1893-1971 (78 years old)
Year of great discovery/work
John Paul established a polio research unit at Yale in the early 1930s and received the first grants from what would later be known as the March of Dimes. He discovered that humans excreted poliovirus in stool samples measureable concentrations of which could be found in sewage areas of those locations experiencing polio outbreaks.
Paul helped figure out how disease outbreaks spread in small communities. This information helps us better understand the disease being tracked.
