This photo, captured in 1961, documents probably the most famous appendectomy in the world, performed by Dr Leonid Rogozov. He was stationed in Antarctica as the only doctor on the team, and couldn't be evacuated when he developed appendicitis. He enlisted a meteorologist and a driver to hold tools and mirrors while he braved the procedure himself through waves of pain and nausea. But it went well, and Rogozov made a full recovery.

What an incredible story!
