Shepherd was a topographical watercolour artist, well known for his architectural paintings. Thomas was the brother of topographical artist George “Sidney” Shepherd, Thomas was employed to illustrate architecture in London, and later Edinburgh, Bath and Bristol. Shepherd’s work, mostly topographical, is characterized by an attention to detail, along with lifelike scenes that contained people, carriages and horses. He worked mostly for Frederick Crace, who employed him to paint old London buildings prior to their demolition, with much of the work surviving in the Crace collection at the British Museum.
