Atkins (1941)

A stockholder of the Hobbs Clock Company who cunningly plays on the "warped senses" of deranged clockmaker Elias Brock in order to make Brock his dupe in a scheme to murder his fellow stockholders and thereby gain a controlling interest in Hobbs Clock.

Brock, a "fanatical old clock maker" suffering from the delusion that he is Father Time, murders two of the stockholders and attempts unsuccessfully to murder a third - each time by means of a booby-trapped clock that releases a deadly gas, fires a poisoned dart, or explodes - after Atkins has persuaded him that the intended victims are incorrigible timewasters, "murderers of time" who are unfit to live.

Brock eventually kills Atkins for making him his dupe in the murderous stock-acquisition scheme, and then dies himself soon aftenvard when, during a scuffle with Batman and Robin, he plummets to his doom from atop the lofty clock tower of the Hobbs Clock Company, where he has planted a massive charge of TNT in hopes of blowing up the tower.
