Paul Joseph Reinmann (1910-1988) was a German-born American comics artist, active during both the "Golden" and the "Silver" ages of comic books. He entered comics in the 1940s and worked on many early superheroes for MLJ Comics (Black Hood, the Hangman and the Wizard), and for All-American Publications (which later merged into DC Comics) working on such characters as the Golden Age Green Lantern, Wildcat, The Atom, Starman and Wonder Woman.

Then he drew for many of the religious, war, western and mystery titles of Stan Lee's Atlas Comics line. Golden Age work for Timely Comics included Human Torch and Sub-Mariner stories in Captain America comics and elsewhere. Reinman worked in other genres for Marvel’s 1950s predecessor, Atlas Comics.

While most of his comics work was of a commercial nature he did create one notable and very personal comic story about his outrage over Nazism and Communism named "Atrocity Story" (1952).

In the late-1950s, he became a frequent inker of Kirby's work in Strange Tales and Journey into Mystery, as well as on the espionage series Yellow Claw and on early issues of Marvel's X-Men and The Incredible Hulk. In 1965, Reinman and Jerry Siegel created The Mighty Crusaders for Archie Comics' short-lived superhero line. He also produced work for the American Comics Group, and remained active through at least the mid 1970s.
