Pratek Man Tuladhar

Born in Kathmandu into a family of hereditary merchants, he spent his youth in Lhasa, Tibet, where they owned a business house.

During his stay in Tibet (1939–1960), alongside his main occupation of conducting trade between India, Nepal and Tibet, he developed an avid interest in collecting photographs, postage stamps and coins.

The firm maintained branches in Gyantse and Phari besides Ladakh and Kolkata in India.

He went to Lhasa again in 1952 and returned to Kathmandu for the last time in 1960, after spending a total of 17 years in Tibet.

The historical trade ended after the caravan route linking India and Tibet through Sikkim was shut down by the Sino-Indian War in 1962.
