Joel L Lebowitz (born 1930) is a leading figure in the field of statistical physics, whose career has spanned more than seven decades and whose work has left a lasting mark on the theoretical foundations of modern physics. He has held academic positions at Stevens Institute of Technology, Yeshiva University and Rutgers University, where he has served as a distinguished professor. Lebowitz is most known for his contributions to nonequilibrium statistical mechanics and mathematical physics, particularly in the areas of thermodynamic limits, phase transitions, and the foundations of nonequilibrium ensembles.

This volume presents the landmark articles that showcase the breadth and depth of Lebowitz's contributions to mathematical physics and statistical mechanics. Ranging from foundational work on nonequilibrium ensembles and quantum measurement to rigorous treatments of phase transitions, transport phenomena, and fluctuation theory, these papers document the development of major ideas in twentieth-century physics. Lebowitz's distinctive approach of combining physical insight with mathematical precision is highlighted clearly, including collaborations with Yakir Aharonov, Peter Gabriel Bergmann, Sheldon Goldstein, Elliott Lieb, Oliver Penrose, Yakov Sinai and Herbert Spohn. This book is both a historical record of scientific progress and a rich resource for active researchers and students in theoretical physics, especially those in statistical physics.
