English sculptor Barbara Hepworth (1903-1975) was one of the most outstanding female artists of the 20th century. Her smooth, massive sculptures invite their audiences to engage with and even touch them, and they stand as icons of the modern movement. But although a figure of international standing, Hepworth never achieved the same degree of recognition in her lifetime as male contemporaries Henry Moore or Ben Nicholson (her husband of nearly 20 years). Travel to the coastal English town of St Ives, where Hepworth lived and worked until her death in 1975, where many of her sculptures were created and where they continue to stand in the environment they were intended for. If you could see one, how would you interact with a Hepworth sculpture? Created by Tate.
