In January, 1917, outside a New York courtroom, the crowd behaved predictably: the same whispers and sly grins, the same ugly innuendoes and unreasoning anger, greeted her whenever she appeared in public ; alone, facing them down, was the little woman with the shy smile and dark, penetrating eyes, quietly determined to speak her mind and persuade those who opposed her of the sanity of her cause. A few months earlier Margaret Sanger had opened the first American birth-control clinic; as a result she had been arrested several times, and now she was charged with violating a state law that prohibited distribution of literature on contraception. The judge promised leniency if she would agree to abide by the law in the future, but Margaret Sanger was determined to test the statute. “I cannot promise to obey a law I do not respect,” she said, and was sentenced to thirty days in the workhouse, where she occupied her time by giving her fellow prisoners lectures on birth control.
