Dr. Heinz Doofenshmirtz, often called "Doof" for short, also known as Professor Time, is a fictional character from the American animated television series Phineas and Ferb. He was created by Dan Povenmire and Jeff "Swampy" Marsh, and is voiced by Povenmire. He was originally depicted as an incompetent and forgetful evil scientist intent on conquering the "entire Tri-State Area" by creating obscure but nefarious inventions. Despite being a villain, Doofenshmirtz is shown to have a good side on some occasions. By the end of the fourth season of the series, the character is redeemed, using his inventions for the good of the world and looking after his daughter Vanessa Doofenshmirtz. Dr. Doofenshmirtz speaks with a caricature of a German accent and is from the fictional European country Drusselstein.

Doofenshmirtz appears in several merchandise pieces, including a book series^[1][2][3][4] and a video game.^[5] He later made an appearance in the Milo Murphy's Law season one episode "Fungus Among Us".^[6] Following his house being destroyed in the second-season premiere, he begins to live in the Murphys' house, and subsequently becomes a major supporting character throughout the rest of the series.^[7]
