Caesar Frank Fiore, 88, a retired Army colonel and telecommunications executive, died of pneumonia Oct. 9 at the ManorCare nursing home in Potomac. He had lived in Arlington for 23 years before moving to the nursing home two years ago.

Col. Fiore, a native of Newark and a 1935 graduate of the U.S. Military Academy, served in the Army for 21 years before retiring in 1965.

During World War II, he commanded the 89th Cavalry Reconnaissance Squadron in the Battle of the Bulge and the fight to capture the Remagen bridge. His post-World War II assignments included service as assistant Army attache in Madrid and duties with Army intelligence.

Upon his retirement from active military duty in 1956, he became a Latin America regional expert for a U.N. international telecommunications standards and development assistance agency. By the 1970s, he opened Intelmar, an international telecommunications marketing firm in Costa Rica, and its U.S. affiliate, Ameritel. He retired from both companies in the mid-1980s.

His first wife, Marjorie Rutherford Fiore, died in 1986.

Survivors include his wife, Jane S. Mock of Fairfax; two children from his first marriage, Tony Fiore of Miami and Elissandra Roy of Bethesda; a sister; eight grandchildren; and three great-grandchildren.
