Early life
Gerson da Cunha was born on 16 June 1929 into a Bombay Goan family of Portuguese descent and grew up in the Mazagaon neighborhood of Bombay (now Mumbai). He graduated in science from the University of Bombay studying at St. Xavier's College. He would later describe his college as a 'fussy and priggish Jesuit College'. His uncle was José Gerson da Cunha, physician and historian, who had written one of the first historical works documenting the origins of Bombay, somewhat aptly titled, The Origins of Bombay. Da Cunha Sr. was also the family physician of the Aga Khan.
