M. Lilian Simpson (c.1871–1897) was a British sculptor.
During the 1890s, Simpson was a student at the National Art Training School, NATS, in London where she was taught by the sculptor Édouard Lantéri.[1] Among her contemporaries at NATS, which became the Royal College of Art in 1896, were a number of other notable female sculptors including Margaret Giles, Ruby Levick, Esther Moore, Florence Steele and Lucy Gwendolen Williams.[2] In 1894 Simpson won a gold medal and travelling scholarship in the National Art Competition for a silver low relief book cover.[1] While still a student, Simpson had two pieces of work, including a bronze casket, shown at the Royal Academy in London and also exhibited with the Arts and Crafts Exhibition Society.[1] In 1896 and 1897 her work was also included in exhibitions in Leeds and Liverpool.[3] In 1897 she used the travelling scholarship she had won in 1894 to travel and study in Italy.[1] There she contracted typhoid fever and died later that year aged 26.[1] The British Library now holds her 1894 book cover.[4]
