Artist, Author. The son of a land surveyor and topographer, Kirby was a landscape painter who served as President of the Society of Artists, officially known as the Incorporated Society of Artists of Great Britain, which encouraged the public exhibition of works of art by living artists. His main artistic focus was “linear perspective,” based on the ideas of English mathematician Brook Taylor. He chronicled his ideas in several books, but is perhaps most noted for his pamphlet entitled: “Dr. Brook Taylor’s Method of Perspective made Easy both in Theory and Practice,” published in 1754. He was the father of British author Sarah Kirby Trimmer. (bio by: Samuel Taylor Geer)  Family links:  Children:  Sarah Kirby Trimmer (1741 – 1810)* *Calculated relationship
