We have so many individuals to be thankful for when it comes to advances in healthcare. From the author of the Kahun medical papyrus, dated at 1800 BCE (and thought to be a copy of an even older document), to the modern-day scientists developing genetically-based cancer treatments, the history of medical science is rich with brilliant innovators. Alas, not all of those innovators were celebrated in their day, while others were even vilified.
