Prof Haley

Walter Mark Haley, known as Prof, was one of four strangers who survived a mysterious plane crash and, believing themselves living on borrowed time, banded together as the Challengers of the Unknown to investigate strange and dangerous phenomena.

Few characters can claim a Silver Age pedigree as storied as Prof Haley's — debuting in Showcase #6 in 1957 under the legendary creative hands of Jack Kirby and Joe Simon, this DC stalwart emerged at one of the most electric moments in comics history. With 65 catalogued appearances spanning an remarkable 64 years, Prof Haley is a figure of genuine longevity, most at home in the pages of Challengers of the Unknown, The Brave and the Bold, and Showcase itself. Along the way, Prof Haley has shared adventures with some of DC's most iconic figures — The Flash, Superman, Batman, Robin, and Clark Kent among them — a testament to just how deeply woven into the fabric of the DC universe this character truly is. With four key-issue appearances to their name, any serious Silver Age collector would do well to seek Prof Haley out.
