The Act was passed following a campaign by Florence Nightingale and Edwin Chadwick and the health section of the National Association for the Promotion of Social Science and some well-publicised deaths of paupers in workhouses. The President of the Poor Law Board, Mr Gathorne Hardy in September 1866, instructed two doctors to visit London workhouses with a view to procuring information which might assist him in drafting new legislation for the reform of workhouse infirmaries. There was a particular concern that those suffering from infectious fevers and smallpox, and the insane, should be removed from the workhouses and treated in separate hospitals.[1]
The area it covered was the Metropolitan Asylums District which included the metropolis as defined by the Metropolis Management Act 1855, excluding the hamlet of Penge.
Despite its name, the MAB was not involved in providing care for the mentally ill. During its lifetime, it set up around forty institutions, beginning with three hospitals for smallpox and fever cases, and two large asylums for what were then termed 'imbeciles' – people with severe learning difficulties.
