Unknown! It's the wife of a famous German Painter! If you recognize the reference to this picture please let me know!!

I've been working on some new mediums. I tried out Watercolor painting for the first time in my life and success! It was a school project, I had to reproduce the painting of a famous artist. Unfortunately, I completely forgot to write down the name of the artist, or the painting for that matter. All I know is that he's a famous German painter and this is a painting of his wife. So please, take a look at it and help me figure out who it is. Send me an email if you can.
