William Collins Engledue

William Collins Engledue (1813 – 30 December 1858), MD (Edinburgh, 1835), MRCS (Edinburgh, 1835), MRCS (London, 1835), LSA (1835) was an English physician, surgeon, apothecary, mesmerist, phrenologist – and, in concert with John Elliotson, M.D., the co-editor of The Zoist.

A former President of the British Phrenological Association, Engledue was ostracized by both his medical colleagues – for his dedication to mesmerism and phrenology – and by the majority of phrenologists – for his rejection of their "socio-religious", spiritual position, in favour of a scientific, materialist, brain-centred position that, in effect, reduced mental operations to physical forces.
