The faculties of universities around the world include people who have made significant contributions to psychology. However, they contain few who have affected their field and those around them as profoundly as has Jack Brehm. Known internationally for his research and theorizing, Jack is also widely admired as a mentor, colleague, and human being of uncommon character. If Jung had known Jack, he likely would have declared him to be someone extraordinarily true to the archetype of the seeker of knowledge. As all who do know him soon realize, Jack marches to the sound of his own internal drummer. And what he marches toward is the goal of pure knowledge and understanding. Regardless of the social, cultural, or professional Zeitgeist, Jack has painstakingly studied what he has found to be interesting. The result has been a powerful body of work that will be utilized and built on for years to come.
