Mr. Daly is credited with brokering many of the deals that put together marketers such as Polaroid and Chemstrand-a chemical company that eventually became Monsanto-with celebrities. Mr. Daly was also central to negotiations that led DDB to become part of the Omnicom Group holding company. "We also had an offer from Saatchi & Saatchi, but he felt we'd be better off with Omnicom. We were one of the last three boards to join," Mr. Reinhard said.
Mr. Daly was chairman until 1989 and later an honorary member emeritus; he was also considered a founder of the agency even though he joined five months after its formation. A decorated World War II hero, he leaves behind three daughters and four sons.
