Hembeck was born January 30, 1953 in Yaphank, New York

Fresh out of college, and failing to get work as a traditional comic book artist, Hembeck hit upon a "bigfoot" style based on the version of himself he used to write illustrated letters to his college friends. Hembeck used this character to conduct comedic "interviews" with Spider-Man and the Flash, and sent them off to the leading fan publication of the day, The Buyer's Guide for Comic Fandom (now known as the Comics Buyers Guide). Much to his surprise, the submissions were published, and Hembeck's strip, called "Dateline: @!!?#" became a popular feature. The "best" of these strips were published in Hembeck: The Best of Dateline: @!!?#, put out by Eclipse Comics in 1979, and reprinted by FantaCo Enterprises in 1980.

From 1979—1981, Hembeck wrote and drew a 3-panel comic strip that appeared in the Daily Planet page of DC comic books. (The Daily Planet featured news on current and upcoming DC comics and answers to reader questions.)

From 1980 to 1983, FantaCo produced a series of black-and-white magazine-format books featuring Hembeck's stories and strips. Hembeck also contributed humor pieces to other FantaCo titles, including Smilin’ Ed, the Chronicles series, Gates of Eden, and Alien Encounters.

Marvel Age and Brother Voodoo

Hembeck was especially visible in the 1980s when his strips appeared regularly in Marvel Age, a Marvel Comics information magazine. Because Hembeck has a particular fascination with the minor Marvel Comics character Brother Voodoo, he regularly featured the character in the cartoons he drew each month in Marvel Age, generally depicting him as a lame character constantly trying (and failing) to get his own series. Hembeck even introduced Brother Voodoo's "wife" and "child," Sister Voodoo and Voodoo Chile.

When Brother Voodoo finally got his own solo story in Marvel Super-Heroes vol. 3 #1, Hembeck drew it, in a serious art style very different from his normal cartooning look.

In his cartoon in the final issue of Marvel Age Hembeck claimed he had only begun mocking Brother Voodoo because he had the character confused with an "even lamer" Silver Age character, DC's Brother Power the Geek.

Other publications

Hembeck has also been published by First Comics, Krause Publications, Fantagraphics Books, Topps Comics, TwoMorrows Publishing, and Archie Comics.

Many of Hembeck's past strips are available through his website.

Although most of Hembeck's work is itself parody, Hembeck and his drawing style have also been the subject of parody:

• In issue #3 of the first Omega Men series (drawn by Keith Giffen), a team member named "Humbek" appears, drawn in a style approximating that of Hembeck (as opposed to the more representational art of the rest of the issue). His thoughts reveal him to be an underground cartoonist exiled from his homeworld. Seconds later, he is killed by Lobo.
• In a later issue of Legion of Super-Heroes (also drawn by Giffen), the words "I killed Fred Humbeck" appear in the filigree of a panel border.
