Vereeniging voor Vrouwenkiesrecht

Following a succession of benchmarks, first female to take the pharmacist's assistant admission exam, first female to graduate from a Dutch University, first Dutch woman to become a medical doctor, it is without saying that Dr. Aletta H. Jacobs (1954-1929) met some obstacles on her path. Embracing the challenges that came with her passion she took an active interest in social injustice and helped revolutionize the world on many fronts.

Working for suffrage, womens health and workers rights she was a founding member of the Vereeniging voor Vrouwenkiesrecht (Dutch Womens Suffrage Group) founded today in 1894, a founding member of the International Women Suffrage Alliance, a translator bringing International texts on human rights to Dutch readers, a pacifist participating in the first International Peace Conference, and a firm believer and advocate of birth control, opening the first birth control clinics and revolutionizing a little thing often called a diaphragm or "Dutch Cap".
