Kim Deitch (born May 21, 1944 His best-known character is a mysterious cat named Waldo, whose appearance is reminiscent of such black cat characters as Felix the Cat, Julius the Cat, and Krazy Kat.

The son of illustrator and animator Gene Deitch, Kim Deitch has sometimes worked with his brothers Simon Deitch and Seth Deitch. His influences include Winsor McCay, Chester Gould, Jack Cole, and Will Eisner; he attended the Pratt Institute. Before deciding to become a professional cartoonist, Deitch worked odd jobs and did manual labor, including with the merchant marine. Searching for a path, he at one point joined the Republican Party; at another point he became a devotee of Hatha yoga. He joined Bhob Stewart as an editor of EVO's all-comics spin-off, Gothic Blimp Works, in 1969. During this period, he lived with fellow cartoonist Spain Rodriguez in a sixth-floor walk-up apartment in New York's East Village.

Deitch's The Boulevard of Broken Dreams, released in 2002, helped bring his work to the mainstream book trade. The book was chosen by Time magazine in 2005 as one of the 100 best English-language graphic novels ever written.

In 2008, the Museum of Comic and Cartoon Art featured a retrospective exhibition of his work.

He occasionally is even claimed to have overcome Deitch and created the comics himself.

Speaking about Waldo in an interview, Deitch explained:
