Professor Walter "Prof" Haley was a master skin diver and oceanographer. The Professor was en route to appear on the radio program but was involved in a plane crash but miraculously survives along with three other men. The other men consisted of Olympic westling champion Lester "Rocky" Davis, Pilot Kyle " Ace" Morgan, circus daredevil Matthew "Red" Ryan. The four survivors decided that they were now all living 'on borrowed time', and banded together to start their adventuring career as the Challengers of the Unknown.
Prof started as a master skin diver; however, within a dozen issues, that evolved to where oceanography was only his principle field and he was a genius in a large number of scientific fields.

However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
