"Ludwig Haberlandt, physiologist in Innsbruck, tried in the late twenties to develop hormonal contraceptives based on sex hygienic ideas of Sigmund Freud. Although the chemical-physiological knowledge of that time encouraged this plan, after Haberlandt's death in 1932 his tests were dropped and forgotten. It was after World War II, when research in this field was begun in the USA by Gregory Pincus, supported by "Planned Parenthood Federation" under leading of Margret Sanger. Although clinical tests proved to be successful, restrictive social-political conditions in the fifties delayed this project considerably. But in 1958 the first Anti-Baby-Pill reached the US-market."
