Elias G. (Ping) Purdy, 87 a retired civilian employe of the Navy Department who was a baseball player and umpire in this area for many years, died of cardiac arrest Friday in a hospital in Atlanta.

He was a civilian administrative officer in the Navy's Bureau of Medicine and Surgery from the 1920s until retiring in 1951.

Mr. Purdy was a member of St. Anthony's Catholic Church in Washington.

Following the death of his wife, Hazel, in 1969, Mr. Purdy divided his time between Georgia and New Jersey.

He is survived by a daughter, Jean Murry of Atlanta; a son, Robert G. of Morrestown, N.J.; two sisters, Margaret Nichols and Agnes Leathermen of California; five grandchildren, and one great-grandchild.
