I am a designer myself, and so I know who they are because they are very active in the design community, I have interacted with some of them, others I have simply heard good things about.
They are all "leaders" in design, many have written books that are widely available in bookstores, etc.
You can look at their portfolios and get a sense of the broad range of products / services they have completed designs for.
