Frank Phillips, founder of Phillips Petroleum, was one of the most prominent self-made business tycoons of the twentieth century. In Oil Man, Michael Wallis, a best-selling historian of the West, presents Phillips against a pageant of luminaries and outlaws that includes Will Rogers, Harry Truman, Edna Ferber, J. Paul Getty, and Pretty Boy Floyd.

Spanning the final days of America's frontier West through the Roaring Twenties and two world wars, Oil Man is a bold, colorful biography of an original American entrepreneur. A classic work that continues to gather accolades since its original publication in 1988, the book captures the life and times of an American hero.
