IceFrog

IceFrog is a game designer known best for his development of Defense of the Ancients as well as DotA 2 with Valve. His involvement in the Defense of the Ancients series began when he inherited version 6 of the most popular Defense of the Ancients variant called DotA All-Stars. Since then he became well known for his highly-meticulous balancing as well as for staying anonymous and to this date never publicly revealing his real name.
