Edith Martineau, together with her sister Gertrude, was one of a small group of female artists associated with the Pre-Raphaelites.

The daughter of Dr James Martineau, a Unitarian minister and theologian, the artist was born in Liverpool. After studying at the Liverpool School of Art and Leigh's Academy, she became one of the first women to be admitted to the Royal Academy Schools in 1862, regularly exhibiting there and at the Royal Watercolour Society (where she was elected an associate member in 1862), the Grosvenor Gallery and the New Water-colour Society. Her work was also exhibited at the Palace of Fine Arts in 1893 at the World’s Columbian Exposition in Chicago. She died in Hampstead.

Martineau worked in watercolour primarily and is known for her delicately painted and meticulous landscapes which owe much to the Pre-Raphaelites, and genre paintings. Examples of her work can be found in the collection of the Victoria & Albert Museum, the National Gallery of Art in Washington D.C. and other institutions.
