Anthony J. Splendore, who worked for the FBI for 37 years, died Aug. 25 at his home in Reston. He was 98.

The cause was respiratory failure, said his daughter Kate Splendore.

Mr. Splendore worked as a special agent in Richmond, Buffalo and Philadelphia and retired in 1977 as supervisor of the special inquiry section, his daughter said. He later worked for several years as a background investigator for the Peace Corps.

Anthony John Splendore was born in Mount Pleasant, Pa., and came to Washington to work for the FBI as a clerk. He received a bachelor’s degree in accounting in 1943 from Benjamin Franklin University, which became part of George Washington University.

Mr. Splendore belonged to the Knights of Columbus and was a founding member and usher at Our Lady of Grace Catholic Church in Silver Spring, his daughter said. He was a golf club champion at the Leisure World retirement community in Silver Spring, where he lived before moving to Reston.

His wife of 56 years, Mary Sherwood Splendore, died in 1997. His daughter Mary Pat Splendore died in 2010. Survivors include three children, Gerard Splendore of Brooklyn, Kate Splendore of Reston and Jim Splendore of Ridgewood, N.J.; two sisters; and five grandchildren.
