John Wall, a celebrated composer of music, was born at Kensington in 1776. When nineteen years of age he was admitted bachelor of music at Oxford, and having studied under Haydn for about a year, he obtained the degree of doctor in 1800. Besides his Musical Grammar, he composed a great number of original works, and is especially celebrated for his glees. They were collected and published after his death, which took place in 1821.

Sir Augustus, an eminent landscape-painter, brother of the preceding, was born in 1779. His small pictures possess a clearness, depth, and breadth which have seldom been attained by any of the British school. He was admitted an associate of the Royal Academy in 1807, and elected an academician in 1810. His merits as an artist, and his estimable character, obtained for him the Callercotes honour of knighthood in 1837; and in 1844, a few months before his death, he was appointed conservator of the royal pictures. He married Mrs Maria Graham, well known for her travels in India and America. She predeceased him by a short time.
