Biography.
Born in 1921, Shankar started her career in dancing. Her father Bhimrao Shastri was a noted Sanskritist who took active participation in India's struggle for freedom and was a close associate of Mahatma Gandhi. She was the co-editor of 'Harijan'. In 1939, when Uday Shankar brought his dance troupe to Madras (recently renamed Chennai), she joined the Almora Centre to learn Shankar's dance style based on the Indian classics, and became a part of the troupe. In 1941, she married Uday Shankar's younger brother, Rajendra (nicknamed Raju). Her sister Kamala was also a dancer at Uday Shankar's ballet troupe. 
During a period of illness, Shankar had to give up dancing, and already having had a background of Carnatic music, she undertook learning Hindustani classical music for many years under Ustad Abdul Rehman Khan. Later, she also trained with Ravi Shankar, the sitar maestro and youngest brother of Rajendra and Uday.
In 1974, Shankar performed in Europe as part of Ravi Shankar's Music Festival from India. Late that same year, she toured North America with Shankar and George Harrison, who produced the "Shankar Family & Friends" album (1974), including the pop single "I Am Missing You" with vocals by Shankar. Following Ravi Shankar's heart attack during the tour, she conducted his ensemble of musicians.
Shankar has shown her versatility and adaptability by composing music for Bharatanatyam for the leading dance company Shakti School of Bharatanatyam, located in Los Angeles.
Shankar died on 30 December 2013 in California.
