It is not often that one gets to write a preface to a collection of one's own papers. The most urgent task is to thank the people who made this book possible. That means first of all Hy Bass who, on behalf of Springer-Verlag, approached me about the idea. The late Walter Kaufmann-Biihler was very encouraging; Paulo Ribenboim helped in an important way; and Ina Lindemann saw the project through with tact and skill that I deeply appreciate. My wishes have been indulged in two ways. First, I was allowed to follow up each selected paper with an afterthought. Back in my student days I became aware of the Gesammelte Mathematische Werke of Dedekind, edited by Fricke, Noether, and Ore. I was impressed by the editors' notes that followed most of the papers and found them very usefuL A more direct model was furnished by the collected papers of Lars Ahlfors, in which the author himself supplied afterthoughts for each paper or group of papers. These were tough acts to follow, but I hope that some readers will find at least some of my afterthoughts interesting. Second, I was permitted to add eight previously unpublished items. My model here, to a certain extent, was the charming little book, A Mathematician's Miscel lany by J. E. Littlewood. In picking these eight I had quite a selection to make -from fourteen loose-leaf notebooks of such writings. Here again I hope that at least some will be found to be of interest.

In these selections readers are treated to a rare opportunity to see the world through the eyes of one of the twentieth century's most brilliant and sensitive scientists. Conceived by Chandrasekhar as a supplement to his Selected Papers, this volume begins with eight papers he wrote with Valeria Ferrari on the non-radial oscillations of stars. It then explores some of the themes addressed in Truth and Beauty, with meditations on the aesthetics of science and the world it examines. Highlights include: "The Series Paintings of Claude Monet and the Landscape of General Relativity," "The Perception of Beauty and the Pursuit of Science," "On Reading Newton's Principia at Age Past Eighty," and personal recollections of Indira Gandhi, Jawaharlal Nehru, and others. Selected Papers, Volume 7 paints a picture of Chandra's universe, filled with stars and galaxies, but with space for poetics, paintings, and politics. The late S. Chandrasekhar was best known for his discovery of the upper limit to the mass of a white dwarf star, for which he received the Nobel Prize in Physics in 1983. He was the author of many books, including The Mathematical Theory of Black Holes and, most recently, Newton's Principia for the Common Reader.

From the foreword by Steven Ellman, PhD: The reader who has not read the papers in this volume is in for a rare treat: the discovery of new worlds revealed within what were thought to be familiar spaces. I believe that those who have already read some of the chapters in this volume will have the experience of rediscovering precious clinical and theoretical gems that have influenced many therapists and analysts. In fact, Bach's influence has quietly spread throughout the field often without various authors fully acknowledging or perhaps realizing his impact on their concepts. I feel certain that readers will share my excitement in reading the chapters in this current volume. Undoubtedly Bach is known for many other contributions to the analytic situation as compared to his statements about analytic trust. For example, he provides us with descriptions of several types of transference in the treatment of narcissistic patients. He features interventions to help bridge the various divides in narcissistic patients. He also points out that in the type of treatments he describes the "analyst's own narcissistic equilibrium is always strongly put to the test." Thus, while I have mentioned that in all of his papers he implicitly describes the therapeutic situation, one might more accurately that he is always looking at the transference-countertransference balance that oscillates in the treatment of narcissistic patients. Of course, it is not surprising that he describes both sides of the analytic couch in sensitive detail. I venture that most (perhaps all) analysts will find important aspects of various patients exquisitely described and understood in this volume. In addition, they will find strong elements of themselves pictured and empathically brought to life.

This book offers a unique compilation of papers in mathematics and physics from Freeman Dyson's 50 years of activity and research. These are the papers that Dyson considers most worthy of preserving, and many of them are classics. The papers are accompanied by commentary explaining the context from which they originated and the subsequent history of the problems that either were solved or left unsolved. This collection offers a connected narrative of the developments in mathematics and physics in which the author was involved, beginning with his professional life as a student of G. H. Hardy.

Filling a void in Jane Addams scholarship, this first volume of The Selected Papers of Jane Addams collects extant documents from the formative years of the major American historical figure, intellectual, social activist, and author. Documenting the early development of Addams's social principles, the documents reveal the leadership skills that led her into a life of public commitment. For all her public compassion and visibility as an outspoken pacifist, Progressive reformer, and founder of Hull-House, Addams was an intensely private person who revealed her personal side only to family and close friends. Drawing on letters, diaries, and other writings from her childhood in Cedarville, Illinois, and her education at the Rockford Female Seminary, this volume provides heretofore unavailable insight into her developing ideas, educational experiences, and personal relationships. More than just biographical records, The Selected Papers of Jane Addams defines the era in which Addams lived. Unique yet representative of the spiritual ideals and political sensibilities of post-Civil War women and society, Addams's lesser-known, personal writings are necessary reading for scholars and historians. The volume explores important themes, including the migration of families westward, the first generation of college women, and the religious and domestic lives of nineteenth-century Americans. The editors' rich annotation of individuals and events featured in the documents and appendix of biographical profiles represent a trove of primary research and place the documents in historical context.

When Margaret Sanger returned to Europe in 1920, World War I had altered the social landscape as dramatically as it had the map of Europe. Population concerns, sexuality, venereal disease, and contraceptive use had entered public discussion, and Sanger's birth control message found receptive audiences around the world. This volume focuses on Sanger from her groundbreaking overseas advocacy during the interwar years through her postwar role in creating the International Planned Parenthood Federation. The documents reconstruct Sanger's dramatic birth control advocacy tours through early 1920s Germany, Japan, and China in the midst of significant government and religious opposition to her ideas. They also trace her tireless efforts to build a global movement through international conferences and tours. Letters, journal entries, writings, and other records reveal Sanger's contentious dealings with other activists, her correspondence with the likes of Albert Einstein and Eleanor Roosevelt, and Sanger's own dramatic evolution from gritty grassroots activist to postwar power broker and diplomat.

One of the best known statisticians of the 20th century, Frederick Mosteller has inspired numerous statisticians and other scientists by his creative approach to statistics and its applications. This volume collects 40 of his most original and influential papers, capturing the variety and depth of his writings. It is hoped that sharing these writings with a new generation of researchers will inspire them to build upon his insights and efforts.
