Allen Tough (1936 – 27 April 2012) was a Canadian educator and researcher. Widely known as a futurist, scientist, and author, Tough was Professor Emeritus at the University of Toronto at the time of his death. He made major contributions to the fields of Adult Education, Futures Studies, and SETI. Linking these fields together was Tough's concern with the long-term future of humanity in the cosmos, and humankind's search for meaning and purpose on personal, societal, and global levels. He taught at the Ontario Institute for Studies in Education (OISE), University of Toronto, for 33 years, retiring from teaching in 1997. After his retirement he devoted his time and energy to his research interests.
Allen Tough was born and raised in Toronto, Ontario, Canada. During his years as a student at the University of Toronto, Tough's interests included psychology, sociology, philosophy, global issues, alternative futures, journalism, youth and adult education, as well as soccer, skating, dancing, campus publications, and wilderness hiking. He served as Editor-in-Chief of the all-campus yearbook for two years, recruiting and supervising a staff of 40 volunteers.
During his twenties, Tough taught high-school English and Guidance for two years, earned his M.A. at the University of Toronto, married and began his family, earned his Ph.D. at the University of Chicago, and became an assistant professor at the University of Toronto. In Chicago, in line with his focus on the psychology of adult learning and change, he did a Ph.D. internship in conference planning and wrote his Ph.D. thesis on the behavior of adults during self-directed learning projects.
Until the end of the 1970s, Tough's line of research focused on the adult's successful efforts to learn and change, particularly the 70% of adults who are self-guided without relying much on professionals or institutions. His first books, The Adult's Learning Projects and Intentional Changes, were based on his thesis research.
For more than four decades Tough was globally recognized as a pioneering scholar in adult learning, self-directed growth, and personal change. His contributions to the field date from the 1960s, and his research illuminated adults' successful efforts to learn and change. More than 90 major studies in eleven countries were based on Tough's early work.
