'Sarat Chandra Bose's forefathers had served the Afghan rulers of pre-Mughal Bengal with great distinction. He was born to Janakinath Bose (father) and Prabhabati Bose (née Dutt) in Howrah on 6 September 1889. Prabhabati Bose was part of the famous Datta family of Hatkhola in north Kolkata. She gave birth to fourteen children, six daughters and eight sons, among whom were nationalist leader Sarat Chandra Bose, Netaji Subhas Chandra Bose and distinguished cardiologist Dr. Sunil Chandra Bose.
Sarat Bose married Bivabati Dey in 1910 and the couple had eight children. The children included Sisir Kumar Bose, who became a pediatrician and Member of Parliament, and Subrata Bose, who was an electrical engineer and also a Member of Parliament.
In January 2014, Sarat Chandra Bose Memorial Lecture was instituted and the maiden lecture was delivered by international historian Leonard A. Gordon, who has penned a joint biography of Sarat and his younger brother Subhas, titled Brothers Against The Raj.
