Suzanne Herz, the Doubleday senior veep who has worked closely with that imprint’s signature authors John Grisham and Dan Brown, has been upped to EVP and Executive Director of Publishing. She continues to report to Anthony Chirico, President of Knopf Doubleday Publishing Group. Here’s the just-released internal memo from Chirico:

It gives me great pleasure to announce that Suzanne Herz, Senior Vice President, Publishing, Doubleday, is being named Executive Vice President, Executive Director of Publishing, Doubleday. The appointment takes effect immediately, and she will continue to report to me.

Suzanne has been a driving force behind some of our most successful publishing campaigns. Her work with Dan Brown and John Grisham has helped those authors to become global brands and enjoy successive multimillion-copy #1 bestsellers.

John Grisham writes, “I have worked with Suzanne for almost twenty years. I value her creativity, honesty, diplomacy, patience, but above all, her loyalty.”

And Dan Brown writes, “Since our earliest adventures with The Da Vinci Code, Suzanne has continuously charmed, coaxed, and cajoled me into all sorts of media appearances that I have tried very hard to decline. Suzanne’s powers of persuasion combined with her superb market instincts and tireless efforts in all aspects of publicity and marketing have contributed enormously to the success of my books. For this, and for so much else, I feel honored to have her as a colleague and trusted friend.”

Of course, Suzanne’s contributions at Doubleday range far beyond her work with Dan and John. She brings creativity and energy to every book on the list, and it shows in the marketing, advertising and publicity campaigns she supervises. Suzanne comes to projects armed with ideas (“A cover reveal via tile puzzle!”) and initiatives (“A simulcast from Lincoln Center!”) – as her recent campaign on behalf of Dan Brown’s Inferno attests (her prior campaigns for The Da Vinci Code and The Lost Symbol were both recognized by Advertising Age with a “Marketer of the Year” award). Her knowledge and savvy have earned her the trust of authors, the respect of agents, and the admiration of her colleagues.

Another of Suzanne’s attributes is her ability to work well with others. She shares an extraordinary partnership with Editor in Chief Bill Thomas, a partnership that Sonny Mehta and I have come to rely on. Under Bill’s leadership, and with support from the rest of the Doubleday and Nan A. Talese teams, Bill and Suzanne have built one of the most dynamic lists and publishing programs in the industry, a list that includes Margaret Atwood, Chris Bohjalian, Bill Bryson, Pat Conroy, Jon Krakauer, Jonathan Lethem, Ian McEwan, Candice Millard, Erin Morgenstern, Chuck Palahniuk, Edward Rutherford, and Jeffrey Toobin, among others.

As Suzanne begins her third decade with our group, she is as energized and focused as ever, and her sunny disposition and preternatural exuberance remain intact (Sonny describes these as perhaps her most enviable traits).

Please join me in congratulating Suzanne on her promotion, and wishing her well in the years to come.
