Behold Man [antikvár]

iiilSlÄSlPSi rnmíímmmw^^ mmmm Preface When we began work on this book we knew that we would never be able to describe the human body in complete detail. It would take more than a lifetime to draw a full portrait of man using the variety of electronic and optical instruments currently available. Our bodies arc too complex, many processes are not yet understood, and others can not yet be reproduced photographically. We have worked with the pictures in this book for many years and are pleased to be able to present them now as a kind of first report. New optical systems, lenses with extremely short focal lengths and wide visual angles, which we were able to develop with the aid of international experts, have made it possible to observe and film parts of the body never before photographed. We hope that in some instances this technique has provided new information. For example, our photographs of the interior of various blood vessels, which, among other things, show the changes associated with arteriosclerosis, drew attention to our technique when they were published in L/fe magazine and won awards from the American Heart Association. What we have done could not have been done without the collaboration of experts in many different fields. We are grateful to all who have helped us and their names, individuals as well as institutions and organizations, are listed at the end of the book. In particular. Dr. Lena Lagerstrom has played a most active role. Her contribution is exceptional, and we realize that without her, many of the photographs appearing in the book would never have been taken. Our especially warm thanks go to her. Stockholm, August 1973 Lennart Nilsson Jan Lindberg
