On March 2, 2009, a special session of the 49th Sanibel Symposium, at St. Simons Island, Georgia, was held to honor the memory of William H. Adams. Bill Adams was over many years a frequent participant in the Sanibel Symposia, where he both made scientific contributions and worked in the symposium organization through service as a session chair and in other ways.
The memorial session was chaired by Professor Robert Vergenz, who received his Ph.D. under the direction of Bill Adams in 1989, and is now the faculty of the University of North Florida.
Invited papers in the session were presented by Professor Krzysztof Szalewicz, University of Delaware, Professor Daniel Chipman, Notre Dame University, and Professor Werner Kutzelnigg, University of Bochum, Germany.
Bill Adams was scientifically productive to the end of his life; his final article was completed during his last day of consciousness and he delivered it to Professor Bogumil Jeziorski for comments and preservation. We are fortunate in that Professor Jeziorski was able to edit this article for publication (with assistance from Professor Vergenz, who had access to Bill's computer and scientific notes, and from Professor Szalewicz, who was closely familiar with Bill's most recent work).
Following this introduction are a biographical sketch “Remembering Bill Adams” by Professor Vergenz, Bill's final article “Convergence radii of the polarization expansion of intermolecular potentials,” and the paper presented at the Memorial Session by Professor Kutzelnigg, “How many-body perturbation theory (MBPT) has changed quantum chemistry.”
As also pointed out in the biographical sketch, notes and supporting data for William Adams' professional activity have been deposited with Robert Vergenz, Department of Chemistry, University of North Florida, Jacksonville, FL 32224.
