Marie Seymour Lucas

Marie Seymour Lucas née Marie Elizabeth Cornelissen (1850–1921) was a French-born English painter.

She was the daughter of Louis Dieudonné Cornelissen and Marianne, née Bath. She attended St. Martin's Lane Academy and later the Royal Academy, where she began showing her work in 1877. She married the painter John Seymour Lucas the same year and was thus only known professionally by her married name. She is known for historical works and genre scenes, but she later concentrated on domestic scenes with children.

Her painting of orphans We are but little children weak, nor born to any high estate was included in the 1905 book Women Painters of the World.

She died in Hendon, Middlesex.
