William T. Powers, the engineer/psychologist who developed Perceptual Control Theory (PCT) passed away on May 24, 2013 at the age of 86. He will be laid to rest next to his wife, Mary, in a cemetery overlooking the city of Durango, CO. His work will continue, pursued by those who came to know Powers and PCT. His theory will someday receive the recognition it deserves, and so will he.
