Kevin Eastman was born in 1962 in Portland, Maine, and began drawing as soon as he was able to hold a crayon. His discovery of comic books gave meaning to his crazed doodling. After finding the work of Jack Kirby, Russ Heath, Richard Corben, Vaughn Bode and John Severin, he began to hone his craft. His first published work appeared in 1980, a year before he met Peter Laird. In May 1984, he and Laird published Teenage Mutant Ninja Turtles #1, creating the hit heroes in a half-shell. Eastman co-writes Teenage Mutant Ninja Turtles for IDW.
