René Gimpel (1881-1945) was an influential Jewish Parisian art dealer with galleries in Paris and New York City, who sought to protect art collections from the Nazis in the 1930s and early 1940s, until he was arrested for Resistance activities and imprisoned at the Neuengamme concentration camp in Germany. He died in captivity in January 1945.
Gimpel played an important role in building American art collections between the two World Wars. His father, Ernest Gimpel, operated E. Gimpel & Wildenstein with Nathan Wildenstein in New York, New York, from 1902-1919, and René Gimpel traveled repeatedly to the United States during this time to facilitate sales to collectors in the United States. Gimpel's core business was initially in 18th-century French art, but he later became a key dealer in Impressionist and other 19th-century works by artists including Monet, Cassatt, Degas, Derain, Renoir, and others.
