As noted at
The Hero Initiative:
Born in 1932 in New York City, Dick Giordano rose to prominence in the mid-1960s as executive editor of Charlton Comics' fabled "Action Hero" line, which included such titles as The Question, Blue Beetle, and Captain Atom. In 1969, he moved to DC Comics, where he edited such critically-acclaimed series as Aquaman, Secret Six, Beware the Creeper, Hawk and Dove, and Deadman. In the early '70s, Dick departed DC to found Continuity Studios with partner Neal Adams. Dick returned to DC in 1980 and, as V.P., Editorial Director, presided over relaunches of DC's major characters, including Superman, Batman, and Wonder Woman.
I read all of the comics listed above, and Dick Giordano was for me a signature artist for these comics in the '70s.
