An interactive timeline of the history of anaesthesia

The field of anaesthesia is a subtle discipline, when properly applied the patient falls gently asleep, miraculously waking-up with one less kidney or even a whole new nose. Today, anaesthesiologists have perfected measuring the depth and risk of anaesthesia, but these breakthroughs were hard-won. The history of anaesthesia is resplendent with pus and cadavers, each new development moved one step closer to the art of the modern anaesthesiologist, who can send you to oblivion and float you safely back. This timeline marks some of the most macabre and downright bizarre events in its long history.
