James Mathews Leigh (1808 – 20 April 1860) was an English art educator, painter, writer, dramatist and critic. He is best known as the founder of a popular private art school in London known as "Leigh's Academy", which eventually became the present day Heatherley School of Fine Art.
Leigh was born in London in 1808, the son of Samuel Leigh, a well-known bookseller who ran a shop at 18 The Strand, near the Adelphi Theatre London - William Blake was apparently a frequent visitor. James's uncle was the popular actor and theatre manager Charles Mathews ("the elder"). He studied art under William Etty, deciding to make historical painting his speciality. He first exhibited at the Royal Academy in 1830 with two paintings, Joseph presenting his Brethren to Pharaoh and Jephthah's vow.
Soon afterwards, he went on a tour of the continent, visiting galleries in France, Germany and Italy to study the works of the Old Masters and make sketches. Around this time also he devoted himself to writing, and, in 1838, privately published Cromwell an historical play in five acts, and later The Rhenish Album. He then travelled to Spain where he made further sketches, resuming, on his return to England, work as a painter, and continuing to send paintings of sacred subjects and portraits to the Royal Academy and other exhibitions up to 1849.
However, Leigh is now better known as a teacher of drawing than as an artist. In 1848, he founded an academy of art, "Leigh's Academy", at 79 Newman Street, off Oxford Street in London. It was well attended and became a formidable rival to the other main London art academy run by Henry Sass ("Sass's Academy"). He was said to be "a first rate teacher and a profound critic in matters of art". Many distinguished artists received their early training at Leigh's academy including Sir Frederic Leighton, Sir John Millais, Philip Hermogenes Calderon, Henry Stacy Marks, Edward Poynter, Joseph BoehmEdwin Long, Henry Holiday, Frederick Walker, John Bagnold Burgess and others.
