John H. Conway

John Conway is one of the most prolific mathematicians. He is probably best known for the "Game of Life," which he invented, as well as for "combinatorial game theory" that he developed (partly in collaboration): a very natural and simple definition that lead to a class of games with incredibly rich structure, containing the now-famous "surreal numbers." He has made substantial contributions to many other areas of mathematics, for instance group theory. He greatly enjoys spending time and discussing with students.
