Philip Arch Graham, 79, an area electrician for nearly 40 years before retiring in 1965, died Saturday at Fairfax Hospital after a stroke.

He came to Washington in 1927 and joined the H. P. Foley electrical company, then worked for the Stone & Webster engineering company, from 1947 until joining the Bechtel Corp. in 1960. He retired from that company as an electrical foreman five years later.

He was a member of the Forestville United Methodist Church in Great Falls. He was a mason and belonged to Columbia Lodge in Arlington.

Mr. Graham was born in Wheeling, W. Va., and reared in Staunton, Va. He served aboard battleships with the Navy during World War I, and attended the Electrical Engineering School of Chicago before coming to Washington.

He had resided in Washington and Arlington before moving to Great Falls in 1951.

His first wife, the former Marion Wallace, died in 1959. His second wife, the former Esther Koneczny, died in 1979.

Mr. Graham's survivors include a daughter, Ann G. Hazzard of Glen Echo Heights; a son, Philip W., of Arlington; two sisters, Elizabeth Gorecki of Bethesda, and Edith Purpura of Long Island, N.Y., and seven grandchildren.
