Christopher M. Peterson (1950-2012).

Presents an obituary for Christopher M. Peterson. "Other people matter. Period," said Christopher M. Peterson when asked for a concise definition of "positive psychology," the field he helped to found and then helped to guide through the first decade of the 21st century. He researched, taught, and lived positive psychology. When Chris died prematurely on October 9, 2012, in Ann Arbor, Michigan, from sudden heart failure, the world lost a distinguished scholar, an inspirational teacher, and a wonderful human being. Chris loved people. He was genuinely interested in getting to know others. He made everyone around him feel comfortable and respected. An understated, humble, and generous person, it was no accident that his nickname was "Mother Theresa." He always found joy in letting other people shine and sharing the credit with them. He had a gift for seeing the best in each person. He also had a strong sense of fairness and duty without being rigid or allowing his personal feelings to obscure his judgment. He had fun whatever he did and brought fun for others. Although his scholarly contributions are significant, his lasting legacy will be what he shared with other people. So many of us are indebted to him for making us better researchers, better teachers, and better people. (PsycINFO Database Record (c) 2013 APA, all rights reserved).
