The woman behind the pap smear
Co-developer of Pap smear never got paid or acknowledged: Development of the Pap test for cervical cancer has long been credited to George Papanicolaou; however, his wife, Mary, made his discoveries possible, although she was neither paid nor, until recently, credited. Mary not only provided, processed, stained and organized her own daily vaginal samples, she also recruited other women to donate samples that were vital to the identification of precancerous cells.
