Leon G. Hunt, 85, an independent consultant in applied mathematics who specialized in research on health and social issues, died March 5 at a care facility in Washington. The cause was pneumonia, said a daughter, Rachel Hunt.

Mr. Hunt, a resident of the District, was born in Dallas. He was a geologist with Marathon Oil in Michigan, Indiana and Colorado before moving to Washington in 1964. He worked for the Defense Department as a specialist in anti-nuclear submarine warfare and systems analysis before becoming an independent consultant in 1968.

He did research for the Energy Department and other government agencies, nonprofit organizations, and entities including the World Health Organization and the American Petroleum Institute. He retired in 2000.

Ed Greelegs, congressional aide

Ed Greelegs, 66, the former chief of staff to Sen. Richard J. Durbin (D-Ill.) and a veteran of 30 years as a congressional staffer, died March 28 at a care facility in Sarasota, Fla. The cause was complications from Parkinson’s disease, said a friend and family spokesman, Peter Knight.

Mr. Greelegs was a native Washingtonian. He retired in 2007 from Durbin’s staff, which he joined in 1990 when Durbin was a member of the House of Representatives.

Earlier he had served on the staffs of Rep. Martin A. Russo (D-Ill.), Rep. Sam Gejdenson (D-Conn.), and Rep. Bob Eckhardt (D-Tex.). He moved to Florida about five years ago.

Bernice Stavinsky, French tutor

Bernice Stavinsky, 95, who taught French to diplomats posted in Washington and was a lover of things French, including language, cuisine and culture, died April 10 at her home in Chevy Chase, Md. The cause was a stroke, said a daughter, Robin Stavinsky.

Mrs. Stavinsky was born Bernice Seigle in Brooklyn. Her family said she fell in love with the French language as a high school student in New York. In 1954, she moved to Washington after her marriage to Samuel E. Stavinsky, a columnist and editor with The Washington Post.

For 25 years, Mrs. Stavinsky taught French under the auspices of the Welcome to Washington program. She gave lectures at museums in France, on transatlantic voyages to and from Europe and to various groups in Washington. For 25 years, she had a winter home on Singer Island, Fla.
