Camille Claudel (1864 – 1943) was a French sculptor and the mistress of Auguste Rodin.
She had very little formal education, but by her teens – was recognized as a very talented sculptor. When her family moved to Paris, she attended the Colarossi Academy.
In 1883 she became a student (and girlfriend) of Rodin’s, but the relationship went sour. After the break-up, she worked non-stop (to the point of obsession), became very reclusive and lived in complete poverty. She did exhibit many of her pieces, but was also known to destroy everything in her studio. Paranoia followed, as she blamed Rodin for blackballing her and her work.
She was committed in 1914 to an asylum where she stayed until her death. So sad.
