[1][2] Kesar Lall was born in Kathmandu to father Jagat Lal and mother Bal Kumari Shrestha.
This was one of the few places that provided a modern education in Nepal in those days as the Rana government discouraged the establishment of schools.
He traveled across the country, listening to stories and taking down notes in longhand later at home because he said people were shy speaking in front of a tape recorder.
In 1951, following the overthrow of the Rana regime and the installation of a new government, Kesar Lall secured a position as assistant private secretary to Prime Minister Matrika Prasad Koirala.
Kesar Lall joined the US Embassy in Kathmandu in the late 1950s as advisor and translator where he remained until his retirement in 1985.
