Steve Jobs. Few will deny that Jobs had idealized influence, the first factor of transformational leadership often referred to as charisma. Former president of PepsiCo, John Sculley, admitted in his interview in BBC's 2011 documentary on Jobs that to this day he's not entirely sure how jobs convinced him to leave his secure senior executive job at PepsiCo.
