The first Special Olympics games were held on July 20, 1968, at Soldier Field in Chicago. About 1,000 athletes from the U.S. and Canada took part in the one-day event, which was a joint venture by the Kennedy Foundation and the Chicago Park District. Anne McGlone Burke, then a physical education teacher with the Chicago Park District, began with the idea for a one-time, city-wide, Olympic-style athletic competition for people with special needs. Burke approached the Kennedy Foundation in 1967 to fund the event. Kennedy Shriver, in turn, encouraged her to expand the idea beyond the city and the foundation provided a grant of $25,000. When Burke had approached another charity for funding, she was told, "You should be ashamed of yourself putting these kinds of kids on display". The advisory committee to the Chicago Special Olympics included Dr. William Freeberg from Southern Illinois University, Dr. Hayden of the Kennedy Foundation, Dr. Arthur Peavy, Burke, William McFetridge, and Stephen Kelly of the Chicago Park District, as well as, Olympic decathlon champion Rafer Johnson. Kennedy Shriver was honorary chair. At the July 1968 games, Kennedy Shriver announced the formation of Special Olympics and that more games would be held every two years as a "Biennial International Special Olympics". Hayden served as the games executive director through 1972, and then in international development for the games.
