The Honourable John Maler Collier OBE RP ROI (27 January 1850 – 11 April 1934) was a leading English artist, and an author. He painted in the Pre-Raphaelite style, and was one of the most prominent portrait painters of his generation. Both his marriages were to daughters of Thomas Henry Huxley. He studied painting at the Munich Academy where he enrolled on 14 April 1875 (Register: 3145) at the age of 25. Collier was from a talented and successful family. His grandfather, John Collier, was a Quaker merchant who became a Member of Parliament. His father (who was a Member of Parliament, Attorney General and, for many years, a full-time judge of the Privy Council) was created the first Lord Monkswell. He was also a member of the Royal Society of British Artists. John Collier's elder brother, the second Lord Monkswell, was Under-Secretary of State for War and Chairman of the London County Council. In due course, Collier became an integral part of the family of Thomas Henry Huxley PC, sometime President of the Royal Society. Collier married two of Huxley's daughters and was "on terms of intimate friendship" with his son, the writer Leonard Huxley.
