Victor Klee has made significant contributions not only to all of the above fields, but also to mathematics education, mathematical methods in economics and the decision sciences, applications of discrete mathematics in the biological and social sciences, and information linkage between applied mathematics and industry. Rather than attempting to summarize or comment on Victor Klee's numerous professional achievements, we let his vita and bibliography speak for themselves.
Following the spirit of victor Klee's Holistic view of mathematics, the present collection is not divided into mathematical subcategories, but the articles appear in alphabetical order by first author. In order to facilitate browsing through this volume and to give easy access to papers belonging to the same area, we include a list of papers by subject area.
We are indebted to the Center for Discrete Mathematics and Theorectical Computer Science, in particular to its director Daniel Gorenstein, and to the American Mathematical Society for their help in arranging the publication of this volume. We wish to thank the referees for their invaluable help and the authors for their enthusiastic support throughout this project. But, above all we join all contributors in their birthday wishes expressing the deepest gratitude to Victor Klee for all that he has given to us.
