John P. Campbell (1937-2025) was a pioneering scholar in industrial and organizational psychology whose work reshaped the study of job performance. At the University of Minnesota, he built a world-class graduate program and mentored generations of students. His multidimensional model of performance and emphasis on behavior clarified a central problem in the field, while his leadership of Project A influenced modern personnel selection practices. Renowned for both scientific rigor and generous mentorship, Campbell's legacy endures through his scholarship, students, and honors established in his name.
