In the Middle Ages, surgery was performed by barbers due to their skill with sharp instruments. In the mid-19th century, a “grand exhibition” of the effects of laughing gas inadvertently led to the discovery of anesthesia. Three decades later, Louis Pasteur enjoyed a crucial breakthrough in his search for vaccinations because his assistant decided, against his orders, to take a vacation. Here, cardiac surgeon and professor of medical history Jean-Noël Fabiani stitches together the most significant and intriguing episodes from the history of medicine, from chance breakthroughs to hard-fought scientific discoveries. Spanning centuries and crossing continents, this funny, fast-paced yet rigorously detailed graphic novel guides us through one of the most wondrous strands of human history, covering everything from bloodletting to organ donation, X-rays, and prosthetics.
