Thomas Agnew & Sons

Thomas Agnew & Sons is a fine arts dealer in London that began as a print and publishing partnership between Thomas Agnew and Vittore Zanetti in Manchester in 1817. Agnew ended the partnership by taking full control of the company in 1835.

The firm opened its London gallery in 1860, where it established itself as a leading art dealership in Mayfair. Agnew's held a pre-eminent position in the world of Old Master paintings. It also played a major role in the growth of a market for contemporary British art in the late 19th century.

Agnew's closed in 2013. The brand name was sold privately and the gallery is now run by Lord Anthony Crichton-Stuart, a former head of Christie's Old Master paintings department, New York.
