My thanks are due especially to Rackham Holt for her discerning aid in organizing material and for her untiring and inspired advice during the preparation of this book; as well as to Walter S. Hayward whose able assistance has helped to make the task lighter.

In the course of preparing this narrative many books have been consulted. I trust their authors will agree with me that a bibliography in a personal history is cumbersome and accept a general but none the less grateful acknowledgment.

My admiration has always gone out to the person who can put himself in print and set down for historical purposes an exact record of his honest feelings and thoughts, even though they may seem to reflect upon many of his friends and helpers. I have not in this story hurt any one by intent. Because its thread has, of necessity, followed dramatic highlights, many people who played prominent parts have not been mentioned. These I have not forgotten, nor those numerous others who made smaller offerings. Some have pioneered in their special fields and localities; some have given generously and unfailingly of their financial help; some have volunteered in full measure their time and efforts as officers and Committee members; some have fought and labored by my side throughout the years; some have stepped in for only a brief but significant role. Although on the outskirts of the army, it is to these last as well as to those in the vanguard that the advance has been made. And particularly do I wish to thank those co-workers and members of the various staffs whose contributions can in no way be measured by their duties, and whose indefatigable, loyal devotion has been a bulwark of strength to me at all times.

It has been impossible to carry out my sincere desire to give personal and individual recognition and expression of gratitude to all. Neither a history of the birth control movement nor the part I have taken in it could be complete, however, did I not pay tribute to the integrity, valiance, courage, and clarity of vision of the men and women who, year after year, maintained their principles, and never swerved from them in a cause which belongs to all of us.
