Curtis Carr was born in Kansas City, Kansas. While working as a chemist and research scientist for Mainstream Motors, he created an "alchemy gun" capable of transmuting matter from one form to another by an unknown process (wood to glass, etc.). Horace Claymore, the company's president, was impressed until Curtis voiced his intent to keep the device. Claymore argued that since the gun was made on company time, it belonged to Mainstream. When Claymore fired him, Curtis adopted the persona of Chemistro to gain revenge and to extort his former employers.
