Herbert Thomas Dicksee (14 June 1862 – 20 February 1942)[1] was an English painter who specialised in oil paintings of dogs, particularly the deerhound. Prints and etchings of his best-known paintings were widely distributed by publishers such as Klackner of London, and his work is popular among collectors and dog enthusiasts today.

Dicksee belonged to an illustrious artistic family. His father was the artist John Dicksee (1817–1905). John's brother Thomas (1819–1895), also a painter, was the father of Sir Frank Dicksee (1853–1928), president of the Royal Academy from 1924 until his death. (Herbert, meanwhile, had one sister, whose name was Amy.) Dicksee studied art at the Slade School, London, on a scholarship. His first painting was exhibited in 1881.
