First Appearance

Whiz Comics (Feb. 1940)

Note #1: The first issue of Whiz Comics is marked #2 inside. In fact the first four issues of this title are mis-numbered.

Note #2: Whiz Comics was published by Fawcett Publications which was sued in the 1940's by National Periodicals (DC Comics), which claimed Captain Marvel infringed upon their copyright for the character Superman. By the time the trials and appeals had played themselves out in the courts, the comics market had taken a downturn and Fawcett was forced to settle. Fawcett agreed to cease publishing Captain Marvel and sold their remaining characters to Charlton Comics. Decades later DC Comics would lease and eventually purchase the rights to Captain Marvel. Eventually it would also acquire the other Fawcett characters when it purchased Charlton Comics.

The scientific genius of Dr. Sivana made him one of the wealthiest men in Fawcett City, but his unethical business practices also made him one of the most hated men. After his financial empire collapsed, Sivana utilized his genius for criminal profit, but was always captured by Captain Marvel.
