Joel Greenberg will introduce the birding life of Nathan Leopold. Of all the people born in the United States who went on to study birds, Nathan Leopold is arguably the most famous. Unfortunately, however, Nathan’s fame rests on his participation, with Richard Loeb, in the 1924 murder of young Bobby Franks. All previous accounts have glossed over Leopold’s passion for birds. This talk emphasizes Leopold's ornithological work, which did influence aspects of the crime and facilitated his arrest. He was eventually paroled and served at a hospital in Puerto Rico, where he published "The Birds of Puerto Rico."
