Stanton Abner Bennett, 78, a retired electronics engineer with the Navy Department, died last Monday at his home in Arlington. He had cancer.

He was assistant consultant for electronics in the Naval Facilities Engineering Command when he retired in 1969.

Mr. Bennett was born in Brooklyn, N.Y. He earned a degree in electrical engineering from the University of Michigan in 1925. During the 1930s, he worked for several firms in the Boston area, and was a training officer with the Civilian Conservation Corps.

During World War II, Mr. Bennett worked in the radiation laboratory at the Massachusetts Institute of Technology where he helped develop radar components for the Navy.

After serving as a radio engineer at the Navy radio and sound laboratory in San Diego, Calif., he was stationed at the Naval Air Station at Patuxent, Md.; before his transfer to the Washington Navy Yard in 1949.

Mr. Bennett was a member of the Society of Automotive Engineers, the Electronics Industries Associations, the Institute of Electrical and Electronic Engineers and the Institute of Radio Engineers.

He was associated with the Cherrydale lodge of the Masons in Arlington.

He is survived by his wife, Helen T., of Arlington; three children, Barbara A. Saffer of Arlington, Herbert S., of Gaithersburg, and Ruth Anne Kohlmeier of Hinsdale, Ill.; a sister, Elizabeth H., of Los Angeles, and five grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Hospice of Northern Virginia.
