Karl Turnbull is a brand planner and ad agency founder. He has worked on virtually every major beer except Duff and deeply regrets how much processed meat and sandwich dressing he has persuaded Americans to eat. In his parallel career in the arts, he is principal dancer with the Joffrey Ballet and touring keyboardist for Styx. He discovered aluminium, popularized the use of the soup spoon, and was the first domesticated animal to both pilot a light aircraft and sing for Leonid Brezhnev, though not at the same time.
