In what year did Henri Matisse die?

The fact that photography wasn't invented until the 19th century and there's only one choice post-19th century makes the answer an immediate giveaway.

Oh come on, rafter! How can beauty be seen in a series of lines? Your series of lines couldn't possibly be any different from Matisse's lines, now could they!? Just as your series of dots couldn't be any better or worse than Jackson Pollock's series of dots!
