The Autism Society was founded in 1965 by Bernard Rimland, Ph.D. His book,Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior, was written in late 1964 and was one of the first of its kind. In 1968, Ruth Sullivan, Ph.D., became the organization’s first elected president. Over the last 40 years, the Society has grown from a handful of parents into the leading source of information, research, reference and support on the autism spectrum. The Autism Society is the oldest and largest grassroots organization within the autism community.
