Preface

In writing this book about the early days of Bolt Beranek and Newman Inc. (BBN), its growth and development, and the eventual rise of Acentech Incorporated, I have depended on the recollections of many people, from BBN founder Leo Beranek to some of the most recent employees of Acentech Incorporated. Through my interviews with them, they have helped me to understand the history of a unique American company, a pioneer in the field of acoustical consulting. They have recalled for me the special feeling of the place--its intellectual fervor, its spirit of generosity and sharing of ideas, its lack of hierarchy, and the excitement of its employees about new discoveries in their fields. Because I could not interview everyone, I have considered the people I spoke to as representative of various activites and periods at BBN and Acentech.

I began to think of the book less as a formal history than as a group memoir--a collection of personal reminiscences, with some overlaps, repetitions, and occasional disagreements--of the people who had taken such pleasure in working in the relaxed, nurturing, stimulating environment of BBN. The environment seemd ideally suited for encouraging the growth of a new industry of acoustical consulting, spawning generations of distinguished practitioners and many spin-off companies to carry on the work originally begun at BBN. It is a remarkable story.

I am grateful to everyone I interviewed, and I am especially indebted to Bob Hoover, Laymon Miller, and Eric Ungar, who provided me with extensive written materials of their own to draw from, and to Leo Beranek, who was generous in spending time with me and who directed me to his interview with Janet Abbate (IEEE Oral History Center, Rutgers University, New Brunswick, NJ) for biographical information. Finally, Eric Wood, whose idea this book was, has been endlesslly helpful, encouraging, and supportive to me throughout the project. This book would never have existed without him.
