Alexander Robert Hirsch[1] (born June 18, 1985) is an American animator, writer, producer, and voice actor.

[3] In 2018, Hirsch wrote Gravity Falls: Lost Legends which also appeared on The New York Times Best Seller list.

[11] Hirsch went on to attend the California Institute of the Arts (CalArts)[12] where he created a variety of projects and short films including his senior film, Off The Wall, which combined animation and live action and "Cuddle Bee Hugs N'Such" with Adrian Molina, which was chosen by Nicktoons Network for their original series Shorts in a Bunch.

[15][16] He would go on to develop the pilot for the Disney Channel series Fish Hooks along with Maxwell Atoms and future Rick and Morty creator Justin Roiland.

The series, set in the fictional town of Gravity Falls, Oregon, premiered in June 2012[18] with a voice cast including Jason Ritter, Kristen Schaal, and Hirsch himself.

[13] Over the course of the series, he provided the voices of Grunkle Stan, Soos Ramirez,[14] Old Man McGucket, Bill Cipher, and various minor characters.

[31] In February 2018, Hirsch used his Twitter account to announce an official Gravity Falls graphic novel, through a series of puzzle pieces that he would release throughout the day.

[4] Outside of Gravity Falls, Hirsch has done voice work for a number of projects including Phineas and Ferb,[34] Rick and Morty, and as the announcer for the Chelsea Peretti special, One of the Greats.

[40] Alex is currently in development on an unknown adult animated series for the company that remains NDA protected as of 2022 with no known release or announcement date as of yet.

[54] According to Hirsch, Ariel "really did wear wacky sweaters and have a different ridiculous crush, every week" in a similar fashion to Mabel.

[61] Hirsch has argued that Disney diminishes LGBTQ+ content by censoring or removing it to appeal to conservative viewers; by giving it less care, quality assurance, and merchandise; and limiting creative freedom in its television animation studios.

[62][63] In November 2020, Hirsch prank-called Rudy Giuliani's voter fraud hotline set up by the Donald Trump campaign, by using the voices of multiple Gravity Falls characters to report Hamburglar-esque ballot theft.
