Inserting adults with psychic problems into families has recently been practiced in various European countries and also in Italy, where some mental health departments support such families. Beyond the well known story of Gheel, the etero and omofamily care of psychiatric patients has a forgotten history. Methods – On the basis of unexplored and exceptionally rich sources from the archives of the asylums in Florence, as well as of the Province di Florence, which funded assistance to the mentally ill – this research focuses on the subsidized “domestic custody” of hundreds of psychiatric patients, who had already been institutionalized. Beginning in 1866, outboarding was supported by the provincial administration in Florence with the collaboration of the asylum medical direction. Results – In the late 19th C. and in the early 20th C. prestigious psychiatrists sought alternatives to the institutionalisation. These alternatives involved varied participants in a community (the patients and their families, the administrators and the medical specialists, the neighborhood and the police). The families played a special role that historians of the psychiatry exclusively dedicated to the insane asylums have not really seen. Conclusions – The role of the families in the interaction with the psychiatric staff is not, even on a historiographical level, simply an additional and marginal chapter of the practices and of the culture of the mental health. These archival evidence contradicts some common places on the past of the Italian psychiatry before 1978, and provokes new reflections of possible relevance to the present.
