Wolf Wolfensberger was born in Germany in 1934, emigrated to US in 1950, received his PhD. in 1960, and began a career that had him living in Omaha, Nebraska, Toronto, Ontario, Canada, and eventually Syracuse, New York, where he lived for the rest of his life. But wherever he lived he was always traveling around the world spreading ideas for much-needed reform of services to people with intellectual impairments – ideas that have indeed had world-wide impact. This book reviews various areas and angles of his work commemorating the scholarship and influence of this giant in the field of human services of the second half of the 20th century.
