Would you be brave enough to cut into someone’s head and work on their brain? Henry Marsh is a courageous doctor and skillful surgeon who has saved thousands of lives by doing this very difficult work. For years, he has taken out people’s brain tumors and fixed life-threatening problems. He was one of the first surgeons to operate while the patient was awake and able to answer questions. That helps the doctor to do his or her best during the operation. The American public television network made The English Surgeon, a documentary about Mr. Marsh and his work. Last year, he wrote a best-selling book, Do No Harm, about his life’s work as a brain surgeon.
