This book is a tribute to Jack Steinberger (1921-2020) whose contributions play an important role in the development of particle physics. Together with Leon M Lederman and Melvin Schwartz, he was awarded the 1988 Nobel Prize in Physics for the discovery of the muon neutrino. The book begins with an introduction by Julia Steinberger and a collection of photographs of Jack Steinberger, followed by the sharing by Jack's former colleagues, students, and friends of their interactions with him on research in physics as well as many personal reminiscences. The second part of the book is a special collection of published works by Jack Steinberger and collaborators and a commentary by W-D Schlatter on Jack Steinberger's early papers, Nobel Prize experiment, CP-violation in kaon decay, CDHS neutrino experiment, and ALEPH e?e? experiment.
