The Sanibel Symposia have a long tradition of paying homage to the outstanding persons of the quantum chemical community. At the end of this session on correlation, I would like to take a few minutes to evoke the memory of Carl Moser, who passed away last December.

Carl Moser was an unusual quantum chemist. Until the end of his life, he was “un américain à Paris,” an American in Paris.

Carl had already begun his pioneering work on atoms and correlation in the 1950s. As a young student, I worked hard on a contribution to the book on “correlation” that he edited and that was published as a large volume of Advances in Chemical Physics. That book was followed by the best-seller of the 1960s, the famous Quantum Chemistry by Raymond Daudel, Roland Lefebvre, and Carl Moser.

Carl pioneered the development of scientific cooperation in Europe. The meeting in Blaricum, Holland, that he organized in 1969 was the origin of Le Centre Européen de Calcul Atomique et Moléculaire (CECAM), the European Center for Atomic and Molecular Computation, which is still operating in Lyon.

Carl Moser was instrumental in bringing together scientists from all over the world for extended interaction and collaborative work. Today we quantum chemists have access to powerful computers. The 1970s were different. Carl understood very early that a large-scale computer would offer the opportunity to develop links between people. As a result of his action, many of us present today at St. Simons Island have met on the campus of Orsay. May I ask all of you to stand for one minute of silent remembrance of Carl Moser. Thank you!
