In 1959, Searle had applied to license the "Pill" - an oral progestin - as a contraceptive. They chose Dr John Rock to present the findings of the experiences of 897 women before the Food and Drug Administration (FDA). Rock (1890-1984) was an American obstetrician and gynecologist who was an expert in human fertility, the requirement at the time was that a drug must be proven safe and not necessarily effective. However, the young reviewer, who was aware of the implications of the Pill, was thorough in his examination, requiring further lab tests before approval. By 1964 some four million women were on the pill.*
