I don't know too much about him except for a few things:
- I have seen his paintings in person from time to time, at the Art Institute of Chicago and The Museum of Modern Art in NYC, among other places.
- My painting teacher is a fan of his.
- He made of series of "Computer Paintings", one of which I have seen in person, which interest me because of the mark-making language he engages with in them.
- He is German and alive :)
