Richard Feynman was an American physicist and Nobel Prize winner. Through his stamp collecting he discovered Tuva - a remote region of Russia close to the Mongolian border.
He fell in love with the place but died a week before he finally got a visa to visit.
Ilona Vinogradova from the Russian Service takes his daughter Michelle to visit the land of nomads and throat singers that her father dreamt of.
