The Artist's Studio (L'Atelier du peintre)

The Artist's Studio (L'Atelier du peintre): A Real Allegory of a Seven Year Phase in my Artistic and Moral Life, 1855, 359 × 598 cm (141.33 × 235.43 in), oil on canvas, Musée d'Orsay, Paris

I have always wanted to know who were all those people in Courbet's studio. So I did some research and added the identifying titles to the painting as best I could determine. If there are errors, please let me know.
