Pierre Guillaumat, 82, French war minister under the late President Charles de Gaulle and subsequently founder of the oil company Elf-Aquitaine, died Wednesday in Paris. He was decorated for his role in the French Resistance during World War II and went on to serve as de Gaulle's war minister from 1958 to 1960. He later headed several major companies, proving himself to be a rigorous and demanding manager. He founded Elf Aquitaine in 1965 and served as its chairman for 12 years.
Florence Seibert, developer of the test for tuberculosis, died Aug. 23 in St. Petersburg, Fla. She was 93. While on a scholarship to Yale University, she developed a procedure for ridding distilled water of fever-causing contaminants to make it safe for intravenous transfusions. In later work at the University of Pennsylvania and the University of Uppsala in Sweden, she isolated the active substance in tuberculosis, then helped develop a technique to separate TB protein molecules so they could be used in a skin test. Her test became the U.S. government's standard in 1941.
