Dorothy Weiner and about 10 others, including Tom Wittick, established the Insane Liberation Front in the spring of 1970 in Portland, Oregon. Though it only lasted 6 months, it had a notable influence in the history of North American ex-patients groups. News that former inmates of mental institutions were organizing was carried to other parts of North America. Individuals such as Howard Geld, known as Howie the Harp for his harmonica playing, left Portland where he been involved in ILF to return to his native New York to help found the Mental Patients Liberation Project in 1971. During the early 1970s, groups spread to California, New York, and Boston, which were primarily antipsychiatry, opposed to forced treatment including forced drugging, shock treatment and involuntary committal. In 1972, the first organized group in Canada, the Mental Patients Association, started to publish In A Nutshell, while in the US the first edition of the first national publication by ex-mental patients, Madness Network News, was published in Oakland, continuing until 1986.
