Much of the previous century’s medical progress is owed to the bravery of a few pioneering researchers—unlikely heroes who needed human test subjects and decided that the only ethical option was self-experimentation. Featuring engaging reenactments as well as present-day expert interviews, this four-part series explains how a handful of scientists contributed to some of medicine’s greatest breakthroughs by turning themselves into human guinea pigs. Viewers will gain detailed historical knowledge about anesthetics, vaccines, infectious diseases, and the links between food and health—in addition to learning about the work of today’s self-experimenters. A BBCW Production. 4-part series, 51 minutes each.
