She was born in Ambala, Punjab into a Bengali Brahmo family. Her father worked as a medical officer, a job that required many transfers. As a result, she attended a number of schools, her final degree is a Master’s in History from St. Stephen’s College, Delhi. This was a time when the country’s atmosphere was charged with nationalist sentiments and the freedom struggle was gaining momentum. She was not born with a steely will and exemplary leadership qualities. Rather, she was a shy child, self-conscious about her appearance and intellect, as she points out in her book, An Unfinished Autobiography. It was the age she grew up in and the situations she faced that shaped her personality. Sucheta recounts how, as a 10-year-old, she and her siblings had heard their father and his friends talk about the Jallianwala Bagh massacre. It left them so outraged that they vented their anger on some of the Anglo-Indian children they played with, by calling them names. Her exact words were- “I could understand enough to feel great anger against the British . We vented out anger on some of the Anglo-Indian children who played with us, calling them all kinds of names,” Both Sucheta and her sister Sulekha were desperate to join India’s burgeoning Independence movement. There is one particularly fascinating incident which Sucheta narrates in her book. After the Jallianwala Bagh massacre, the Prince of Wales had visited Delhi. Girls from her school were taken to stand near the Kudsia Garden to honour the Prince of Wales. Despite wanting to refuse, both the sisters couldn't, and that left them bitterly outraged at their apparent cowardice. “This did not absolve our conscience from feeling shame. We both felt very small of our cowardice,” she writes. Later, while a student of Kinnaird College in Lahore, her Bible class teacher had said some disparaging things about Hinduism. Furious, Sucheta and her sister went home and asked their father to help them out. He coached them on some religious teachings and, the next day, the girls confronted their teacher with quotes from the Bhagavad Gita. The teacher never referred to Hinduism in class ever again! She studied at Indraprastha College and Punjab University before becoming a Professor of Constitutional History at Banaras Hindu University. In 1936, she married J. B. Kripalani, a prominent figure of the Indian National Congress, who was twenty years her senior. The marriage was opposed by both families, as well as by Gandhi himself, although he eventually relented.
After independence, she remained involved with politics. For the first Lok Sabhaelections in 1952, she contested from New Delhi on a KMPP ticket: she had joined the short-lived party founded by her husband the year before. She defeated the Congress candidate Manmohini Sahgal. Five years later, she was reelected from the same constituency, but this time as the Congress candidate. She was elected one last time to the Lok Sabha in 1967, from Gonda constituency in Uttar Pradesh. Meanwhile, she had also become a member of the Uttar Pradesh Legislative Assembly. From 1960 to 1963, she served as Minister of Labour, Community Development and Industry in the UP government. In October 1963, she became the Chief Minister of Uttar Pradesh, the first woman to hold that position in any Indian state. The highlight of her tenure was the firm handling of a state employees strike. This first-ever strike by the state employees continued for 62 days. She relented only when the employees' leaders agreed to compromise. Kripalani kept her reputation as a firm administrator by refusing their demand for a pay hike. When Congress split in 1969, she left the party with Morarji Desai faction to form NCO. She lost 1971 election as NCO candidate from Faizabad. She retired from politics in 1971 and remained in seclusion till her death in 1974.
