John Benjamin Murphy, born John Murphy (December 21, 1857 in Appleton, Wisconsin – August 11, 1916 Mackinac Island, Michigan), was an American physician and abdominal surgeon noted for advocating early surgical intervention in appendicitis appendectomy, and several eponyms: Murphy’s button, Murphy drip, Murphy’s punch, Murphy’s test, and Murphy-Lane bone skid. He is best remembered for the eponymous clinical sign that is used in evaluating patients with acute cholecystitis. His career spanned general surgery, orthopedics, neurosurgery, and cardiothoracic surgery, which helped him to gain international prominence in the surgical profession. Mayo Clinic co-founder William James Mayo called him "the surgical genius of our generation".
