Mark Erdel

Professor Mark Erdel was a world-famous scientist who built a "robot brain" which he hoped to explore space and other dimensions.

Background Information
In the parallel universe, known as Earth-One, Professor Erdel's' first test of his "robot brain" resulted in the arrival on Earth of the Green Martian known as J'onn J'onzz. The excitement of the experience seemed to be too much for Professor Erdel. He died of an apparent heart attack brought on by the shock of meeting his alien guest.

Years later, an investigation by the Thanagarian heroes known as Hawkman and Hawkgirl revealed that Erdel was actually killed by an invisible alien "wyrdbeast" from Alpha Centauri transported to Earth by Erdel's device.
