Evelyn Slater, who served as a secretary to two U.S. senators from the 1950s to the 1970s, died Dec. 31 at her winter home in Oxford, Fla. She was 97.

From 1951 to 1962, she was a secretary to Sen. Leverett Saltonstall (R-Mass.). Mrs. Slater served as executive secretary to Sen. Charles M. “Mac” Mathias Jr. (R-Md.) from 1963 until her retirement in 1976.

Doris Evelyn Fey was born in rural Webster County, Neb., and graduated from high school in Red Cloud, Neb. She later moved with her family to a farm near Rushville, Ind. She graduated in 1940 from Hiram College in Ohio.

Mrs. Slater lived in Kensington, Md., and later Hagerstown, Md. She moved to Indianapolis in 1997.

She was a member of the Eastern Star masonic organization and the Washington National Cathedral Association.

Her husband of 63 years, Kenneth B. Slater, died in 2005. He played trumpet in the U.S. Marine Band, known as “The President’s Own,” and later with the Army Field Band.

She had no immediate survivors.
