Which of these artists created "When Will You Marry?"?

"When Will You Marry?" is an oil painting from 1892 by the French Post-Impressionist artist Paul Gauguin. On loan to the Kunstmuseum in Basel, Switzerland for nearly a half-century, it was sold privately by the family of Rudolf Staechelin to Sheikha Al-Mayassa bint Hamad Al-Thani, in February 2015 for close to US $210 million (£155 million), one of the highest prices ever paid for a work of art. The painting was on exhibition at the Fondation Beyeler, Riehen, until 28 June 2015.
