Joseph Gregoire deReoulhac Hamilton Jr., 71, a retired Washington bureau chief of the Columbus (Ohio) Dispatch and press secretary for Rep. Chalmers S. Wylie (R-Ohio), died of intestinal bleeding and cardiac arrest Sept. 11 at the National Orthopaedic & Rehabilitation Hospital in Arlington.

Mr. Hamilton came to Washington following World War II duty as a Marine Corps combat correspondent in the Pacific and China. He was a reporter for out-of-town newspapers and radio stations and later became the chief partner of the old Hamilton-Means Associates, a news service.

From 1966 to 1971, he was bureau chief of the Columbus Dispatch. He spent the next five years as the newspaper's chief Washington correspondent. In 1976, he became press secretary for Wylie, a post he held until retiring in May of this year.

He was a member of the Congressional Radio and Television Correspondents Association.

Mr. Hamilton was a native of Raleigh, N.C., and a 1932 graduate of the University of North Carolina. During the 1930s, he worked for several newspapers in the Carolinas, including the Raleigh News and Observer and the Charleston News and Courier.

His marriage to Billie Bamberg ended in divorce.

Mr. Hamilton's survivors include his wife, Lillian Brunson Hamilton of Arlington; a daughter by his first marriage, Fay H. Gwynn of Decatur, Ga.; a brother, Dr. Alfred T. of Raleigh, and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to a charity of one's choice.
