Who are the most famous modern day artists and what type of work are they most famous for?
The best I can do is to point to Wikipedia:
They list a lot more artists than I'm familiar with, and have a bunch of different categories mixed in there...you didn't mention performance art, painting, dance, etc, which it seems Wikipedia groups altogether in one big list. Hope this helps.

Yes, www.wikipedia.com is a good resource.
