Kalpana Datta

Kalpana Datta (Bengali: কল্পনা দত্ত) (27 July 1913 – 8 February 1995) (later Kalpana Joshi) was an Indian independence movement activist and a member of the armed independence movement led by Surya Sen, which carried out the Chittagong armoury raid in 1930. Later she joined the Communist Party of India and married Puran Chand Joshi, then General Secretary of the Communist Party of India in 1943.

Kalpana Datta (also commonly spelt Dutta or Dutt) was born at Sripur, a village of Chittagong District in the Bengal Province of British India (Sripur is now located in Boalkhali Upazila in Bangladesh). After passing her matriculation examination in 1929 from Chittagong, she went to Calcutta and joined the Bethune College for graduation in Science. Soon, she joined the Chhatri Sangha (Women Students Association), a semi-revolutionary organisation in which Bina Das and Pritilata Waddedar were also active.

The Chittagong armoury raid was carried out on 18 April 1930. Kalpana joined the "Indian Republican Army, Chattagram branch", the armed resistance group led by Surya Sen in May 1931. In September, 1931 Surya Sen entrusted her along with Pritilata Waddedar to attack the European Club in Chittagong. But a week before the attack, she was arrested while carrying out reconnaissance of the area. She went underground after her release on bail. On 17 February 1933 the police encircled their hiding place and Surya Sen was arrested but Kalpana was able to escape.

She was finally arrested on 19 May 1933. In the second supplementary trial of the Chittagong armoury raid case, Kalpana was sentenced to transportation for life. She was released in 1939.

Kalpana Datta graduated from the Calcutta University in 1940 and joined the Communist Party of India. She served as a relief worker during the 1943 Bengal famine and during the Partition of Bengal. She wrote an autobiographical book, Chittagong Armoury Raiders: Reminiscences, published in English in 1945. In 1946, she contested in the elections for the Bengal Legislative Assembly as a Communist Party of India candidate from Chittagong but could not win.

Later, she joined the Indian Statistical Institute where she worked until her retirement. She died in Calcutta on 8 February 1995.

In 1943, she married the then General Secretary of the Communist Party of India, Puran Chand Joshi. They had two sons: Chand and Suraj. Chand Joshi was a noted journalist, who worked for the Hindustan Times. He was also known for his work, Bhindranwale: Myth and Reality (1985). Chand's wife Manini (née Chatterjee) penned a book on the Chattagram armoury raid, titled, Do and Die: The Chattagram Uprising 1930-34.

In 2010, Deepika Padukone starred as Kalpana Datta, in a Hindi movie, Khelein Hum Jee Jaan Sey, which dealt with the Chittagong armoury raid and its aftermath. Another movie, Chittagong, was released on 12 October 2012, based on the uprising. It was produced and directed by Bedabrata Pain, an ex-NASA scientist.
