[1] Lewin spent nearly 48 years at the Scripps Institution of Oceanography at the University of California at San Diego and was considered a leading authority in multiple areas of marine biology.
He addressed this issue frankly by stating, "Whereas food has always received much attention in conversation, commerce, and the literature, the subject of feces has been comparatively neglected.
The present article aims to supplement this book with a review of overlooked or new items relating to biological and medical aspects of coprology, notably chemical and microbial components of human and animal feces, their uses as fertilizers, and a few other sociological impacts."
Ralph Lewin was an Esperantist, and was Ordinary Professor (orda profesoro) at Akademio Internacia de la Sciencoj San Marino, the only university in the world where all courses are studied in Esperanto.
[1] He translated Winnie-the-Pooh into Esperanto with Ivy Kellerman Reed, and was the author of Merde: excursions in scientific, cultural and socio-historical coprology.
