Ishwar Chandra Vidyasagar was associated as the Secretary with the Hindu Female School, which later came to be known as Bethune Female School.

Explanation:

Ishwar Chandra Vidyasagar was a prominent social reformer, philosopher, and educator in 19th-century India. He played a significant role in the upliftment of women and the advancement of education in the country.

The Hindu Female School was established in 1849 by John Elliot Drinkwater Bethune, who was a civil servant of the British East India Company. The school aimed to provide education to girls from Hindu families, which was a novel idea during that time when education for girls was not widely encouraged.

Ishwar Chandra Vidyasagar joined the school as the Secretary in 1850. As the Secretary, he worked tirelessly to improve the educational standards and curriculum of the school. He introduced several reforms, including the inclusion of subjects like mathematics, science, and history in the curriculum, which were traditionally not taught to girls.

Under Vidyasagar's leadership, the Hindu Female School flourished and gained recognition for its commitment to providing quality education to girls. In 1878, the school was renamed Bethune Female School in honor of its founder, John Elliot Drinkwater Bethune.

Vidyasagar's association with the Bethune Female School was instrumental in breaking the barriers of gender inequality in education. He firmly believed in empowering women through education and worked towards creating equal opportunities for girls to acquire knowledge and skills.

Vidyasagar's contributions to education and social reform in India were immense. He not only championed the cause of women's education but also played a vital role in the abolition of the practice of Sati (burning of widows on their husband's funeral pyre) and advocated for widow remarriage.

In conclusion, Ishwar Chandra Vidyasagar was associated as the Secretary with the Hindu Female School, which later became known as Bethune Female School. His efforts and reforms in the field of education have left a lasting impact on the empowerment of women in India.
