Yes, 75 is fairly young, but ad legend Hal Riney was battling cancer. He began his career at BBDO, before moving on to Ogilvy and then founding Hal Riney & Partners in 1985. He has left us memorable campaigns such as Saturns strategy "a different kind of company, a different kind of car" the two old men who were Bartles and Jaymes, and even Reagan's 1984 campaign.
