Phyllida Barlow, a specialist in sculpture and installation, taught at the Slade School of Art in London for decades. Some of her students, such as Rachel Whiteread and Martin Creed, became famous – but for more than 40 years she remained in the background, although she consistently created works in her own studio. Even when no one was there to see her art, she kept making it. One project saw her go out at night alone and throw artwork into the River Thames. Here she is in her studio in 2012.
