#13 Joan Jonas
With a career spanning nearly 60 years, 80-year-old Joan Jonas is still on the cutting edge of contemporary art. Jonas' mixture of performance art, dance, and video art has been performed in and collected by museums around the world. Among her many accomplishments is having been the sixth woman ever to represent the US at the Venice Biennale. In 2018 she will be the subject of a retrospective at the Tate Modern.
