Jeff "Swampy" Marsh

Jeff "Swampy" Marsh (born December 9, 1960 in Santa Monica, California) is a British-American animator, writer, director, producer, and voice actor associated with several animated television series, most notably as an executive producer and the voice of Major Monogram for Disney's animated series Phineas and Ferb and Milo Murphy's Law, both of which he co-created with Dan Povenmire. Marsh was born in Santa Monica, California, where he grew up with a heavily blended family dynamic. Marsh has been and continues to be a driving force behind several animation projects, working for over six seasons on the animated television series The Simpsons. Marsh continued to work on other animated television series, including King of the Hill and Rocko's Modern Life, before moving to England, United Kingdom in 1996.

While in England, Marsh worked on several animated programs, including Postman Pat and Bounty Hamster, and worked for BKN New Media Ltd. to produce several feature films. After six years living in England, Marsh was asked by his longtime partner Dan Povenmire to help produce Phineas and Ferb in 2007, a concept the two had while working together on Rocko's Modern Life. Marsh accepted and moved back to the United States; the series has since garnered Marsh two Emmy Awards nominations for songwriting. According to an original pitch extra of Phineas and Ferb, he prefers having "Swampy" in his name, because it made his name 15 letters long and longer than most other people's names. As of 2015, he and Povenmire are currently producing a new series for Disney XD titled Milo Murphy's Law, which premiered on October 3, 2016. Marsh has also developed an animated TV series for Amazon Prime based on the Pete the Cat children's book series, with the first season premiering in September 2018. His recent work includes Phineas and Ferb the Movie: Candace Against the Universe, which was released on Disney+ on August 28, 2020.
