A pioneer in the birth control movement both in the United States and abroad, Dr. Clarence J. Gamble began his work as a volunteer in Philadelphia in 1929. Because he was convinced that the health and happiness of women and children and, in fact, entire families depended on adequate spacing of their babies, he helped to establish family planning clinics in a dozen American cities before he was forty years old. Dr. Gamble's major concern was to provide a safe, reliable, and cheap contraceptive that poor women who had no access to running water or modern conveniences could use. After World War II and the population explosion that followed it, Dr. Gamble expanded his efforts in what he called the Great Cause to help those in the developing nations who wanted their people to be able to choose when to have children and how many to have. Every Child a Wanted Child is more than the biography of a unique man. It is a record of the ups and downs of the birth control movement in the United States and in Italy, Japan, India, and parts of Asia and Africa.
