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.
