Ralph H. Bogle Jr., 58, president of R. H. Bogle Company in Alexandria who was active in civic and charitable organizations, died of cancer Tuesday in Alexandria Hospital.

Mr. Bogle joined the Bogle Company, which makes weed-killers used along railroad beds, following World War II, and had been president since 1966. His father founded the firm in 1923.

At the time of his death, Mr. Bogle was a director of Burke & Herbert Bank & Trust Co. in Alexandria and a member of the board of St. Agnes Episcopal School.

He had been president of the Alexandria Chamber of Commerce and the Alexandria Kiwanis Club and had served as treasurer and member of the board of Alexandria Hospital.

He had directed charity drives in Alexandria for the Salvation Army, the Red Cross, the American Cancer Society and the March of Dimes.

Mr. Bogle was named Alexandria's "Outstanding Young Man" in 1950 by the Alexandria Junior Chamber of Commerce.

He recently had served as president of the National Railroad Contractors Association.

Mr. Bogle was born in Plainfield, N.J. He was a graduate of Woodrow Wilson High School in Washington and earned a bachelor's degree in chemical engineering at Virginia Polytechnic Institure.

He served as an officer with the 27th Infantry division in the Pacific during World War II, seeing action on Okinawa.

Mr. Bogle was a vestryman and member of the choir at St. Paul's Episcopal Church in Alexandria.

He is survived by his wife, the former Margaret P. Fredette, a son, Ralph H. III, and three daughters, Sara B., Susan P., and Mary J., all of the home in Alexandria; another daughter, Melissa B. Peters, of Florence, S.C.; a brother, John B., of Alexandria, and one grandchild.

The family suggests that expressions of sympathy be in the form of contributions to St. Agnes Episcopal School, to St. Paul's Episcopal Church, or to the Alexandria Hospital. CAPTION: Picture, RALPH H. BOGLE JR.
