At the time of his death in 2010, Dr. Kielhofner was Professor and Wade-Meyer Chair, Department of Occupational Therapy, College of Applied Health Sciences, University of Illinois at Chicago. Dr. Kielhofner is, of course, almost synonymous with his theoretical model -- the Model of Human Occupation (MOHO). In their tribute to Dr. Kielhofner, Drs. Braveman, Fisher, Suarez-Balcazar wrote the following (Braveman, Fisher, Suarez-Balcazar, 2010. p. 829):
In 1980, Gary and Janice Burke introduced a theoretical model under the mentorship of Mary Reilly to fill a gap in understanding and addressing clients with disabilities' psychosocial challenges in the rehabilitation process (Kielhofner & Burke, 1980). This groundbreaking theory, the Model of Human Occupation (MOHO), is currently the most widely used theory in occupational therapy research and practice. This model presented practitioners with a conceptual framework and practical tools to guide their assessment and reasoning process, effect change, and measure the impact of their intervention. It guides occupational therapy practitioners to consider the personal values and interests, roles and responsibilities, and environmental contexts of each client. The model also provided a foundation for program development and research initiatives. Gary's book, Model of Human Occupation: Theory and Application, now in its fourth edition, has served to educate generations of occupational therapy students (Kielhofner, 2008). More than 500 articles, books, and chapters have reported research, case studies, intervention approaches, and programs based on MOHO.
In 2011, Dr. Kielhofner, received the American Occupational Therapy Association's Award of Merit (posthumously). AOTA created the The Gary Kielhofner Emerging Leader Award and awarded it for the first time in 2014 to Rachel Dargatz. AOTF created The Gary W. Kielhofner Graduate Fellowship in Occupational Therapy to also further his impact. Dr. Kielhofner was named one of the 100 Influential People in Occupational Therapy by AOTA.
