Each book in the 50 Classics series has been a major effort, involving thousands of hours of research, reading, and writing. Beyond this core work, the series is made successful thanks to the team at Nicholas Brealey Publishing.
I’m very grateful for the editorial input of Nicholas Brealey and Sally Lansdell in NB’s London office, which has made 50 Psychology Classics a better book. Thanks also for the efforts with international rights to ensure that the book will be read by as many people as possible around the world.
Many thanks also to Patricia O’Hare and Chuck Dresner in the Boston office for their commitment to this book and to the 50 Classics series, and for increasing its profile in the United States.
Finally, this book could obviously not have been written without the wealth of remarkable ideas and concepts expressed in the classic books covered. Thank you to all the living authors for your contributions to the field.
