As the field expanded, tensions arose among PPFA, IPPF, the Population Council, and Clarence Gamble. Many in these organizations regarded Dr. Gamble's simple methods and straightforward approach with disdain; his appointment of nonmedical personnel (and women over 50) as fieldworkers, unprofessional; his travels through Asian countries, patronizing; his intrusion into areas staked out by IPPF as their own, intolerable. This was the attitude of Lady Bengal Rama Rau, charismatic chair of IPPF and leader of its India Ocean region, and of Helena Wright, powerful medical director of IPPF. Declaring themselves highly sensitive to the years of oppression waged by white colonists, Rama Rau, Wright, and IPPF maintained that women of whatever color deserved the best that Western medicine could offer—in this case birth control provided by a fitted diaphragm after a preliminary exam by a professional gynecologist.
