The original prospectus of the institute stated The Manchester Mechanics' Institution is formed for the purpose of enabling Mechanics and Artisans, of whatever trade they may be, to become acquainted with such branches of science as are of practical application in the exercise of that trade; that they may possess a more thorough knowledge of their business, acquire a greater degree of skill in the practice of it, and be qualified to make improvements and even new inventions in the Arts which they respectively profess.

[3] Others among the founders were James Murray, Thomas Hopkins, J. C. Dyer and Phillip Novelli, all of whom were later significant figures in the Anti-Corn Law League.

[citation needed] Although the original purpose of the institute was maintained, it was increasingly the case that emphasis was placed also on the wider social aspects of the organisation.

Heywood's initial optimism regarding the moral upliftment of a significant number of working men through technical education was tempered by the realisation that tiredness and even employment status impeded its achievement.

From around 1830, the scope of education was widened to include more elementary aspects, there were proposals to set up reading groups in surrounding areas that would be supplied with books from the institute's library, and also moves to encourage involvement in sports and in general social events.

Facilities for educating women and children were also introduced but, for example, a request to begin classes in history was rejected because of fears that it would lead to debates about politics.
