Ralph S. Rogers, 59, a longtime Washington resident and an agent for National Life of Vermont, died here Aug. 16 after apparently suffering a heart attack in his car.

Mr. Rogers had worked for National Life for the past 18 years, and before that, for the Peoples Life Insurance Co. of Washington.

During World War II, he served in the Marine Corps in the South Pacific. He was twice decorated with the Purple Heart.

Mr. Rogers was born in Richford, Vt., and attended school there. He moved to Washington area about 1940 and returned here after war.

He was a life member of the "Million Dollar Round Table," a professional insurance organization. In 1963, he served as president of the D.C. chapter of the Vermont State Society. He was also a member of the Leaders Club of Washington.

Survivors include his wife, Naomi; a daughter, Jane, and two sons, Charles and David, of the home in Washington; a daughter, Betty Ann Anich, of Denver; two brothers, Arnold, of Gardner, Mass., and William, of Southington, Conn.; four sisters, Joanne Tracy, of Richford, Ruth Ross and Muriel Sullivan of Boston, and Jeanne Ladd, of East Hartford, Conn., and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Church of the Saviour in northwest Washington.
