John Ernest Potzger
(July 21, 1886 - September 18, 1955)

One of the first Americans to follow the research example of Lennart von Post was John E. Potzger. He earned his first two degrees at Butler University in Indianapolis, then obtained the Ph.D. in Botany at Indiana University in 1932. He then returned to Butler University, where he spent his entire professional career as an ardent plant ecologist and pollen analyst. When I taught at Indiana University in the 50s, it used to be said (in jest?) that Potzger and his many students had cored every bog in Indiana and surrounding states.

President, Ecological Society of America, 1954.
