Hegarty has been chosen as one of three new members in the 2005 honours list. The others are Diane Rothschild, the vice-chairman of Della Femina Rothschild Jeary & Partners New York, and Cliff Freeman, the founder of Cliff Freeman & Partners New York.
The One Club pays tribute to the most creative minds in advertising and is among the most prestigious awards for creative directors. Members of the Creative Hall of Fame include David Ogilvy, Bill Bernbach and Jay Chiat. Rich Silverstein, the chairman of Goodby Silverstein & Partners, was added last year.
A founder of Bartle Bogle Hegarty, Hegarty's contribution to advertising includes casting the then-unknown Nick Kamen in the Levi's "launderette" spot, as well as his work on Audi and Johnnie Walker. Rothschild is the first woman to be included since 1969 and Freeman is credited with creating ads including "where's the beef?" for Wendy's.
Mary Warlick, the executive creative director of The One Club, said: "Each of these three outstanding visionaries has touched the advertising industry, not simply leaving their mark, but moulding and changing society."
Hegarty said: "The only other two Britons to be honoured are David Ogilvy and David Abbott. It's great to break the David tradition and start a new one."
