Balthasar Klossowski de Rola, known as Balthus, was a Polish-French modern artist. He is known for his erotically charged images of pubescent girls, but also for the refined, dreamlike quality of his imagery.

Baladine Klossowska or Kłossowska was a German painter. Originating from an artistic Jewish family with roots in Lithuania, she moved from Breslau, Germany, to Paris, France, at the turn of the 20th century, where she was a vivid and active participant in the explosion of artistic experiment then active in the city.
