Who painted this?

"The Boy in the Red Vest", also known as "The Boy in the Red Waistcoat", is a painting by Paul Cezanne, painted in 1889 or 1890. It is an example of Cezanne's skilled, nuanced, and innovative mature work after 1880.

Cézanne painted four oil portraits of this Italian boy in the red vest, all in different poses, which allowed him to study the relationship between the figure and space. The most famous of the four, and the one commonly referred to by this title, is the one which depicts the boy in a melancholic seated pose with his elbow on a table and his head cradled in his hand. It is currently held in Zürich, Switzerland. The other three portraits, of different poses, are in museums in the US.

This painting was acquired from Cézanne by art dealer Ambroise Vollard, probably in 1895, and successively acquired by art collectors Marcell Nemes in 1909 and Gottlieb Reber in 1913. Art collector and patron Emil Georg Bührle purchased it from Beber in 1948. Following Bührle's death in 1956, his heirs donated the painting to the Foundation E.G. Bührle in 1960.

In February 2008, the painting was stolen from the Foundation E.G. Bührle in Zurich. It was the museum's most valuable painting and was valued at $91 million. It was recovered in Serbia in April 2012.
