Even by her own standards, it’s been a big year for Dumas, who last featured in the Power 100 in 2005, when she had a breakout year at the Venice Biennale and became the first living woman artist to sell a work for more than £1 million. Measuring Your Own Grave, the Amsterdam-based painter’s first American retrospective, opened at LA MOCA this summer and is now making its way to MoMA, where it goes on show from December. Oh, and in July The Visitor (1995) was sold for £3,177,250, establishing a new record for the most expensive work to sell at auction by a living female artist.
