Georges Kars was born in the Prague region, where his parents who were grain merchants originally from Germany, had settled. When he was a child, he drew on his school notebooks. After school, he spent time at a gallery run by Lheman. He never missed an exhibition in Prague. He took classes taught by a young painter before leaving for Munich in 1899. There, he studied with Franz von Stuck and became friends with Pascin and Paul Klee. Between 1905 and 1907, he went to Prague and later settled in Madrid, where he met Juan Gris and immersed himself in the paintings of Velazquez and Goya.

In 1908, after a stay in Prague, Kars arrived in Paris and settled in Montmartre. He met his friend Pascin, and got to know Suzanne Valadon and Maurice Utrillo. He also became friends with Chagall, Apollinaire, Max Jacob, the art critic Maurice Raynal, and the Greek painter Demetrius Galanis. During War World I, he was in Belgium with Pascin.

In 1923, he spent the summer in Ségalas, in the Basse-Pyrénées region, with Suzanne Valadon’s family. Under the influence of Paris and Cubism, his shapes became simpler; however, he remained deeply attached to realism. According to him, “art does not lie in an elaborate technique but within the soul.” He produced figurative paintings and used several techniques and materials including Indian ink, watercolor, and pastels. In 1933 Kars bought a house in Tossa de Mar in Catalonia, where he spent three years. Back in Paris, he settled in rue Caulaincourt.

In 1939, he took refuge in Lyon. In 1942, he went into exile and stayed at his sister’s in Switzerland. In 1945, as he could not stand the horrifying tragedy that hit his people, he committed suicide by jumping out of the fifth floor of his hotel.

His studio was sold at auction on June 17, 1966 at the Palais Galliera. In 1983, a retrospective of 120 paintings was held at the art modern museum in Troyes.
