* Gian Carlo Wick; Math Theorem Advanced Physics

Gian Carlo Wick, 82, a physicist who developed a widely used mathematical formula that bears his name. Wick began his career in the 1930s working with Nobel laureate Enrico Fermi. Among the many advances attributed to him was the development in 1951 of a mathematical system for quantum electrodynamics that became a basic tool in all branches of theoretical physics. It is known as the Wick Theorem. Wick came to the United States in 1946 from Italy and taught at the University of Notre Dame, UC Berkeley, the Carnegie Institute of Technology and Columbia University. After retiring from Columbia in 1958, he returned to Italy to teach at the Scuola Normale Superiore in Pisa. In Turin, Italy, on April 20 of cancer.
