Dennis Janke was born on April 13, 1950, and built a steady career as a comic book inker spanning roughly from the mid-1980s to the mid-2000s, working across both DC and Marvel Comics as a freelancer. Though he occasionally penciled covers and interior stories, his primary contribution to the medium came through finish inking over other artists' pencils.
Captain America #308 (1985)
Janke is perhaps best remembered for his nine-year tenure inking Superman: The Man of Steel, where his close collaboration with penciler Jon Bogdanove helped define a particular visual era for the character. He also worked extensively with Jerry Ordway, and together the two co-created Doomsday, the villain whose introduction became one of the most talked-about Superman storylines of the 1990s. Over at Marvel, Janke joined writer Mark Gruenwald and artist Paul Neary to co-create Armadillo, a character who found a lasting home in the Captain America corner of that universe.
World's Finest Comics #306 (1984)
His credits extend well beyond superhero fare. Earlier in his career, around 1975, Janke self-published the underground comics series Flaming Baloney alongside James R. Blevins, signaling an independent streak that ran alongside his mainstream work. Over the course of his career he contributed to dozens of independent and underground titles in addition to high-profile series including Adventures of Superman and The Spectre.
