William Francis Loebs, Jr. (born February 19, 1949 in Ferndale, Michigan) is an American game designer, artist, and comic book writer who has worked for Palladium Books. He is perhaps best remembered as a writer for Wonder Woman.
His right arm was amputated in infancy due to a cancerous tumor. He writes and draws with his left hand.
Note: This person should not be confused with William Loeb, Jr. (1866-1937), presidential secretary to Theodore Roosevelt, or his son William Loeb, III (1905-1981), publisher of the Manchester Union Leader newspaper.
