Sir Edwin Henry Landseer (March 7, 1802 - October 1 1873) was a British painter, well known for his paintings of animals - particularly horses, dogs and stags. The best known of Landseer's works, however, are sculptures - the lions in Trafalgar Square, London.

At the age of just 13, in 1815, Landseer exhibited works at the Royal Academy. He was elected an Associate of the Royal Academy at the age of 24, and an Academician of the Royal Academy five years later in 1831. He was knighted in 1850, and although elected President of the Royal Academy in 1866 he declined the invitation.

Landseer was a notable figure in 19th century British art, and his works can be found in Tate Britain, the Victoria and Albert Museum, Kenwood House and the Wallace Collection in London.

The name Landseer Newfoundland is used for the variety of Newfoundland dog that, rather than being almost entirely black, features a mix of both black and white spots — the variety Landseer popularized in his paintings of water dogs rescuing children from drowning.

Landseer's grave is in St Paul's Cathedral, London.
