Medicine became a science only a few hundred years ago, offering physicians the opportunity to save millions of lives. Unfortunately, some medical practitioners have distorted well-tested medical principles for their personal profit to the detriment of those who suffer the most.

Join us on Thursday, September 18, at 7:00 p.m. ET for a Skeptical Inquirer Presents livestream with Robert Greenspan, MD. This presentation will explore the difference between science and pseudoscience along with the risks faced by those who pursue the latter. As featured in Dr. Greenspan’s book, Medicine: Perspectives in History and Art, this event includes artifacts from his quack medicine collection, one of the largest collections in the world.

This live online event is free, but advance registration is required. Sign up today!

Robert Greenspan, MD*, retired from a forty-seven-year private practice of nephrology several years ago and has always been interested in the history of medicine, which he teaches at the University of Maryland. The skill with which some have misled the public regarding appropriate and available medical care has both interested and bothered him.*
