Aletta Henriette Jacobs, Netherlands (1854-1929)
Denied entry into medical school because she was a woman, Aletta Henriette Jacobs petitioned the Prime Minister of the Netherlands and was granted admission into the University of Groningen. She became the first female medical doctor in Holland. With her father, who was also a physician, she set up free clinics for the poor. In Amsterdam, she established the world's first birth control clinic (1882) and actively campaigned for improvements in health education, change in marriage and prostitution laws, and for female suffrage.
