Warren Zimmermann, 69, the last U.S. ambassador to Yugoslavia before its breakup and civil war, died Tuesday of pancreatic cancer in Great Falls, Va.
A career Foreign Service officer, he was named in 1989 as ambassador to Yugoslavia, where he led efforts to keep the nation together. He resigned from the Foreign Service in 1994 over what he felt was President Bill Clinton's refusal to intervene forcefully in the Bosnia war.
After leaving the Foreign Service, he taught at the Johns Hopkins University School of international affairs and Columbia University. His books include Origins of a Catastrophe, about his experiences in Yugoslavia.
Jerome F. Lederer, 101, who inspected the Spirit of St. Louis before Charles Lindbergh's trans-Atlantic flight and later started NASA's spaceflight safety program, died Friday of congestive heart failure in Laguna Hills, Calif., according to the Flight Safety Foundation, the nonprofit international organization he founded in 1947.
His career spanned aviation from the earliest airmail flights of the 1920s to the space flights of the 1970s. Over those years, he was credited with helping bring about such innovations as equipping planes with black box flight data recorders.
