Richard Rusczyk
Richard Rusczyk is the founder of the Art of Problem Solving website and cowriter with Sandor Lehosczky of the original Art of Problem Solving books. A picture of him can be found here. It is possible to understate his awesomeness but only after expending a great deal of effort. There really should be a lot more stuff that goes here, but I don't know that much about him? Check the About tab.
