Agent Bio
Bob spent 17 years at New American Library [now an imprint of Penguin Random House] in positions ranging from VP Sales to President and Publisher, Chairman and CEO.
There he helped launch the paperback careers of Erica Jong, Robin Cook, Stephen King, Ken Follett, and Robert K Tanenbaum.
With Odyssey Partners, he led the management team of NAL in a leveraged buy out of the company from Times Mirror in 1982, purchased EP Dutton a year later, and sold the combined company to Pearson PLC in 1986, which merged the company with Viking Penguin to create Penguin USA.
Leaving NAL three years later, he opened D4EO Literary Agency in late 1989.
