Architect. Born in Dunkeld, Henry trained in Perth with Andrew Heiton (1823-94) and then obtained a position with David Bryce (1803-76) in Edinburgh. He set up his own practice in Edinburgh in 1883 and went on to undertake some notable work in the city, including the Royal British Hotel on Princes Street (1896), interiors for the Balmoral Hotel (1891) and the Café Royal (1898), together with Midlothian County Council Buildings and the historic Rutherford's Bar (both 1899). He also worked for the Duke of Atholl and was responsible for Dunkeld House (1900) and alterations to Blair Castle (1903-08). He was also responsible for the open-air swimming pool in North Berwick (1929).
Henry lived in the Newington district of Edinburgh and had a reputation as a solid and reliable architect, if not an innovator. He served as President of the Edinburgh Architectural Association (1914-18) and, despite his age, volunteered for service during the First World War. He was one of the founders of the Royal Incorporation of Architects in Scotland and later served as their President.
