John Lambert

John Lambert is the son and heir of David Lambert, "the chemical king" of Apex Chemical Corporation.

Death of his father
Lambert discovered his father in April 1939 dying on the floor of their library with a knife in his back and their safe open. He pulled out the knife only to hear his father's dying words referring to a contract. He was questioned later that night by Commissioner Gordon with Bruce Wayne present. The real culprit was his father's associate, Alfred Stryker, who was inadvertently killed by the Batman.
