Phillip Crane was a highly qualified mehcanical engineer with knowledge of quantum physics and electronics. Crane made a partnership with wealthy businessman, Raymond Aurnau and started working in the man's company, creating incinerating machines for waste disposal management. However, Crane used the company's resources to create a radiation combat-suit and became the villain known as Quantum. When Aurnau learned of Crane's activities, he ended their partnership and Quantum killed the man.

The murder of Aurnau caused Quantum to be confronted by Batman and Superman and during the final struggle, his own equipment caused his disappearance into another dimension.

Even though versions of the character may have since appeared, this information does not apply to those versions.
