Probably born in Carmarthen, south Wales. Architect and engineer. Employed by John Nash. Worked on the layout of Regent's Park and on the construction of the Regent's Canal as Chief Engineer of the Regent's Canal Company. Designed and supervised first the Maida Hill and then the Islington tunnel. Resigned as Chief Engineer in 1835 following a dispute with the committee. Designed the mechanism for the London Diorama, a site near this plaque, which opened in 1823. Was living in Hammersmith when he died.
We cannot find an image of Morgan himself so have used one showing the construction of his greatest achievement - the Islington Tunnel. Our Picture source is very informative on Morgan.
