The 50th annual Sanibel Symposium, organized by the faculty, staff, and students of the Quantum Theory Project of the University of Florida, was held from February 24 to March 2, 2010 at The King and Prince Beach and Golf Resort, St. Simons Island, Georgia. This venue continues to provide excellent, conference facilities and an atmosphere that, although a bit more upscale, is reminiscent of the hotel at old Sanibel Island, Florida, where the first several symposia were held. About 350 participants gathered for 7 days of lectures and informal discussions and to celebrate the 50th anniversary of this international gathering of researchers in the quantum sciences.

The format of the symposium followed the tradition of this annual meeting offering a compact schedule with an integrated program of theory and computation in biology, chemistry, and condensed matter physics. A special characteristic of this symposium, celebrating half a century of science, was that each plenary session featured a pioneer in the particular subject matter, a current leading scientist, and a junior researcher. Each session was chaired by a scientist who had provided decades of leadership. So, in addition to current research, each session provided a retrospective and a glimpse into the future. The topics covered by the plenary and poster sessions of the symposium include: Density functional theory, molecular electronics, molecules, c1usters and materials, density matrices, coupled cluster theory, propagators, analytical properties, quantum dynamics, clusters and solids, dynamics of biomolecules, software for electronic structure, and others.

The program consisted of twenty-one plenary sessions and seven poster sessions. These proceedings contain papers from most of these sessions and have been subject to the normal referring procedures of the International Journal of Quantum Chemistry.
