Bina Das was an Indian revolutionary and nationalist from West Bengal.

St. John's Diocesan Girls' H.S. School is a girls-only day school located in Kolkata (Calcutta), West Bengal, India. It was established in 1876 by British missionary Angelina Margaret Hoare from Kent, England who devoted her life to the advancement of women's education in British India. It is a Christian school run by the Protestant Church of North India and its primary language of instruction is English. The school's patron saint is Saint John the Baptist. Although previously a college, the school was stripped of its college status by the British Government when freedom-fighter Bina Das, a student of the school, attempted to assassinate the Governor of Bengal, Stanley Jackson.
