In 1883, Chandramukhi Basu and Kadambini Ganguly became the first female graduates of India and the British Empire, paving the way for other women, as Haimabati Sen in 1894. By the way, these two women had made their marks on history from other viewpoints. In fact, Kadambini Ganguly was also among the first women to practice western medicine in Asia, and the first woman to get admission to Calcutta Medical College, while Chandramukhi Basu was also the first woman head of an undergraduate academic school, namely Bethune college, in South Asia.
