For those who have come of age in a country where the crisis of mental health often tops the headlines, it can seem inconceivable that within living memory people who experienced mental health difficulties were often ignored and locked away.
Describing himself as a mental health system survivor, the activist Peter Campbell, who has died aged 73, experienced the old psyschiatric asylums as well as the newer systems of care in the community that replaced them. He worked for more than 40 years to end the marginalisation of those subject to the powers of the mental health system, and to help people who live with mental health difficulties find a collective and credible voice to advocate for change.
