Convicted burglar Mark Mardon was being escorted by train under guard to Tri-state Prison, when he jumped from the moving train and headed for the home of his brother Clyde, who lied on an island in Big Water Lake.

Entering his brother's lab, Mardon found Clyde dead of a heart attack. Near his brother's hand he found a notebook containing details of experiments in controlling the weather. Clyde had intended to use these discoveries in order to help humanity, and was about to announce his findings publicly when he died.

Mark Mardon, howeer, was going to use these discoeries to help himself! Using his own inventive skill and following the principles Clyde had discovered, Mardon built a wand that would enable him to control the weather over limited areas. He then created the costumed identity of the Weather Wizard.

As the Weather Wizard, Mardon set out on a revenge mission against the three police officers who had arrested him. He suceeded in getting the first two men, but was prevented by the Flash (Barry Allen) in his attempts to get the third.

The Weather Wizard later created a weather control station and used frigid weather to cut Oakley County, Wyoming, off from the rest of the country. His next plan was to build a gigantic weather control station from which he could tak eover the whole country. His plans were foiled by Wally (Kid Flash) West and the Elongated Man.

Since then, Weather Wizard has battled Batman, but his most regular opponent was Barry (Flash). On occasions he teamed up with other members of the rogues gallery to overcome Barry but without success.
