Although he hasn't invented any amazing techniques yet, Sanjay Gupta is probably the most well known surgeon alive. He is a practicing neurosurgeon, as well as being a medical correspondent for CNN. Indeed, he has won an Emmy and contributed to the Peabody honor for CNN during Hurricane Katrina. Rumors are that he was offered the post of Surgeon General when Barack Obama took office (he asked to have his name withdrawn from consideration). He is the author of bestselling books, as well as a columnist and health advocate.
