inscribed 'Abbaye près de Sarlouis'. Sandby continued to draw a salary from the Board of Ordnance, and this, together with his appointment as deputy ranger of Windsor Great Park, which he held till his death, placed Sandby in a position of independence, and afforded scope for his talent both as an artist and as an architect. The Great Lodge (now known as Cumberland Lodge) was enlarged under his supervision as a residence for the Duke. The lower lodge was occupied by himself. His time was now principally spent in extensive alterations of the park, and in the formation of the Virginia Water Lake, in which he was assisted by his younger brother, Paul, who came to live with him. In 1754, Thomas made eight drawings of the lake which were engraved on copper by Paul Sandby and other engravers and dedicated to the Duke of Cumberland. They were republished by John Boydell in 1772. George III, who took great interest in the undertaking, honoured Sandby with his confidence and personal friendship, and on the death of Cumberland in 1765, the king's brother, Henry Frederick (also Duke of Cumberland, and ranger of the park), retained Sandby as deputy. Artist and professor of architecture Although devoted to his work at Windsor and preferring a retired life, Sandby spent part of each year in London. He rented a house in Great Marlborough Street from 1760 to 1766. He was on the committee of the St. Martin's Lane Academy, which issued a pamphlet in 1755 proposing the formation of an academy of art, and he exhibited drawings at the Society of Artists' exhibition in 1767, and afterwards for some years at the Royal Academy. Both he and his brother Paul were among the 28 original members of the Royal Academy who were nominated by George III in 1768. He was elected Academy's first professor of architecture, delivering the first of a series of six lectures in that capacity on 8 October 1770. He continued these lectures with alterations and additions annually till his death. They were never published, but the manuscripts were held in the library of the Royal Institute of British Architects. The illustrations were sold with his other drawings after his death. Architect In February 1769 Sandby entered a competition to design the Royal Exchange at Dublin, winning third prize of £40. Perhaps his most notable architectural commission was the design of
