Warrington Academy, active as a teaching establishment from 1756 to 1782, was a prominent dissenting academy, that is, a school or college set up by those who dissented from the established Church of England. It was located in Warrington (then part of Lancashire, now within Cheshire). Formally dissolved in 1786, the funds then remaining were applied to the founding of Manchester New College in Manchester, which was effectively the Warrington Academy's successor, and in time this led to the formation of Harris Manchester College, Oxford.
A statue of Oliver Cromwell stands in front of the academy.
It was called "the cradle of Unitarianism" by Arthur Aikin Brodribb writing in the Dictionary of National Biography, who went on to say that it: "formed during the twenty-nine years of its existence the centre of the liberal politics and the literary taste of the county of Lancashire". It was planned in 1753, to replace other training schools in northern England having funding from the English Presbyterians: Caleb Rotheram of the Kendal academy died in 1752, and Ebenezer Latham of the Findern and Derby academy in 1754. It was not, however, formally constituted till June 1757, when funds had been raised by John Seddon of Warrington. The first site was the Cairo Street Chapel; subsequently the building was a large red brick house.
Three tutors were chosen initially: John Taylor, of Norwich, taught divinity; Mr. Holt, of Kirkdale, natural philosophy; and John Aikin, classics.Henry Willoughby was the first president of the academy. Soon a fourth tutor was appointed. On the death of Dr. Taylor, in 1761, Aikin became tutor in divinity, and was succeeded in his old duties by Joseph Priestley. Among the other tutors who at some point joined the staff of the academy were Johann Reinhold Forster, William Enfield, George Walker, Nicholas Clayton, and Gilbert Wakefield.
