Leonid Ivanovich Rogozov (1934 – 2000) was a Soviet general practitioner who took part in the sixth Soviet Antarctic Expedition in 1960–1961.
He was the only doctor stationed at the Novolazarevskaya Station and, while there, developed appendicitis, which meant he had to perform an appendectomy on himself, a famous case of self-surgery.
The operation took 2 hours. He positioned himself so that he could see his own body using a mirror when doing the surgery - he made a 12 cm cut through which he found the appendix. After 5 days the doctor felt good, and after 7 days he removed the wires which had been used to sew up the body.
