Professor Haley

A Silver Age fixture of DC's beloved Challengers of the Unknown, Professor Haley made his debut in 1959 — courtesy of creators Ed Herron and Bob Brown — and has kept remarkable company ever since, sharing pages with the likes of Ace Morgan, Red Ryan, Rocky Davis, Arthur Curry, and Dinah Lance across nearly five decades of comics. Though his catalog footprint is modest, his presence stretches from 1959 all the way to 2005, a quiet testament to the lasting pull of the Challengers universe. For collectors hunting the corners of DC's Silver Age, Professor Haley is exactly the kind of character who rewards a deeper dig.
