Ewing Thomas Boles (May 4, 1895 – November 16, 1992) was an American investment banker and philanthropist who served as president, CEO and chairman of the Ohio Company (now merged with Fifth Third Bank).
That organization which would again change its name to Phi Kappa Tau in 1916 became a major focus of Boles' volunteer work for the rest of his life.
Boles entered the University of Kentucky Law School but gave that up to enter the United States Navy during World War I. Boles worked in Chicago after the war, and held other positions before joining BancOhio Securities Company (later the Ohio Company) at Columbus, Ohio in 1929.
[1] Boles' two major philanthropic interests were Centre College and Phi Kappa Tau Fraternity and its educational foundation.
In recognition of his lifelong commitment to the fraternity, he received the North American Interfraternity Conference gold medal in 1985.
