McDowell, Ephraim

Ephraim McDowell (November 11, 1771 – June 25, 1830) was an American physician. He was the first to successfully remove an ovarian tumor. McDowell was the great great grandfather of General John Campbell Greenway, whose statue was placed in the National Statuary Hall Collection by the state of Arizona in 1930.

John Campbell Greenway (July 6, 1872 – January 19, 1926) was an American mining, steel and railroad executive. He also had a distinguished career as a soldier, both cavalry and infantry. Beginning in 1899, Greenway held executive positions in a number of mine, steel, and railroad companies. He supervised development of United States Steel's open pit Canisteo Mine and Trout Lake Washing Plant in Coleraine, Minnesota, one of the first large-scale iron ore benefication plants in the world. Following the successful commissioning of the Trout Lake plant, in 1911 Greenway was recruited by the Calumet and Arizona Mining Company (led by US Steel executives) to develop their newly acquired New Cornelia Mine in Ajo, Arizona. He developed the Ajo townsite and developed the New Cornelia into the first large open pit copper mine in Arizona. Greenway served for one year as a regent of the University of Arizona before the United States entered World War I. In 1930 Arizona placed Greenway's statue in the U.S. Capitol's National Statuary Hall Collection. The statue of Greenway's great great grandfather, Dr. Ephraim McDowell, was placed in the National Statuary Hall in 1929 by Kentucky.
