Alexander "Alex" Robert Hirsch (born June 18, 1985) is the creator and executive producer of the Disney XD Animated Series Gravity Falls. He voices the main characters Grunkle Stan and Soos, as well as recurring characters like Old Man McGucket, Bill Cipher, and the Gnomes. His twin sister is Ariel Hirsch.
He places many of his real-life experiences in the show, such as living in Piedmont and trick-or-treating with his sister as cats. He based Mabel on his twin sister, Ariel Hirsch, Grunkle Stan off of his Grandpa Stan and based the entire show loosely on his childhood summers. He gave Mabel a pet pig because his sister had always wanted one when she was a kid.
