When my father August Krogh died in 1949, 1 was with him in Den• mark. My stay in Denmark was prolonged for another two months due to a concussion 1 sustained in an automobile accident, which occurred shortly after his death. It was then that 1 became familiar with the ex• tensive material of biographical value which my father had left. Due to the pride and interest August took in his family, the material was very rich, consisting of family letters going back to his mother's birth in 1842, his own letters to his mother, father and siblings, between his siblings, between himself and my mother as well as his children. It in• cluded correspondence with his colleagues, university matters, Marie Krogh's letters, numerous notes and manuscripts, books, and scientific papers. It became clear that 1 was the one to write the biography because 1 was a physiologist. In addition, 1 spoke and wrote English as well as Danish and 1 very much wanted to undertake the project. My brother, Erik, was to inherit the material, but he was not inclined to undertake such a major job and he as well as Torkel Weis-Fogh (my father's scien• tific assistant) encouraged me to write the biography. It seems an awfully long time between making the decision and fin• ishing the work. 1 began immediately after having had the material shipped to Duke University, but soon found that it was impossible to combine such a major undertaking with my other work (research, teaching, and taking care of my three children). My resolve was undi• minished, but 1 had to put the writing on hold until my life became less complicated, which did not happen until after 1 retired. Weis-Fogh and 1 deposited the material in the Danish Royal Library in Copenhagen in 1964. During the intervening years, 1 continued to collect material of biographical significance. Then in 1987 the work began in earnest, but before 1 could start writing 1 had to copy all of the material we had deposited in the Danish Royal Library. Writing the book has been an absorbing and deeply rewarding un• dertaking. In studying my father's and mother's writings and correspon• dence, 1 have come to admire them even more than 1 had before. As my mind filled with what 1 read and then wrote, my parents carne vividly alive at all the various stages of their enormously productive lives. 1 have been asked if 1 learned things about them that 1 did not know before. 1 vi Preface certainly did, but the image of these two people who were my parents did not change, only the depth of understanding. 1 also arrived at the sobering realization that many thoughts, beliefs, and ideas that 1 had believed were original to me have come to me through what my parents taught me when 1 was a child.
Gainesville, Fla. B. S.-N. ]uly 1994 Acknowledgments
In this- undertaking I have had a great deal of help and encouragement. In copying the files from the Royal Library in Copenhagen, my grand• niece Maria Krogh Nielsen assisted me and Librarian Troels Lauring of Nordisk Insulin Laboratory kindly completed the task. All of it is now in my home in Gainesville, Florida. It is said that nothing is written until someone has read it. The first one to read my draft, encourage me and make small corrections was always my patient and beloved husband, Roger Chagnon. Next carne my excellent editor Miss Susan Williams who helped get the Danish out of my English, then carne my "two pro• fessors," Dr. Thomas Maren and Dr. Arthur Otis. I had told Tom Maren that I needed a critica! audience. He suggested forming a small commit• tee consisting of himself and Dr. Otis. During the years that I have been writing I regularly brought my pages to them. We would have lunch together while they read the next installment of the Krogh saga. I can• not thank these two friends enough for their never failing encourage• ment and kind suggestions. I have also regularly sent my manuscript to my family in Denmark, who have helped me with suggestions and more material and to Dr. Erik Hohwii Christensen in Sweden. Dr. Chris• tensen's review of my chapter on exercise was very helpful. Dr. Michael Bliss kindly reviewed the chapter on insulin and Dr. Hans U ssing the isotope chapter. My former teacher and lifelong friend, Else Rahbek, was always willing to help me contact people in Denmark or find mate• rial I needed. When I had almost finished, Dr. John West recommended the manuscript to the American Physiology History Section and to Oxford University Press, for which I am grateful. The last and least-pleasant part has been to condense my manu• script. I was told by the publisher it had to be shortened by about a third but given no specific guidelines for what to take out. An excellent editor in New York, Ms. Beverly Pennachini, has been sufficiently tough-minded to help me take out the less essential material. Contents
