"Thomas Sandby RA (1721 – 25 June 1798) was an English draughtsman, watercolour artist, architect and teacher. In 1743 he was appointed private secretary to the Duke of Cumberland, who later appointed him Deputy Ranger of Windsor Great Park, where he was responsible for considerable landscaping work.
Along with his younger brother Paul, he was one of the founding members of the Royal Academy in 1768, and was its first professor of architecture. His most notable architectural work was the Freemason's Hall in London (now demolished)." - (en.wikipedia.org 03.01.2021)
