Input: Question: When did King Tribhuvan die? Passage:However his work visa expired in the UK and he only had a League of Nations Refugee Passport. In the 1930s he got work in Bombay and traveled in Ceylon, Indochina, Malaya, Shanghai and then went back to India and stayed in Calcutta, where, with the help of his friends, he founded "Club 300". Lisanevich was the person who introduced the famous dish, Chicken a la Kiev, to Calcutta as a menu item at "Club 300". The club was opened in 1936 and he ran it until 1946 and then left for New York City; subsequently he came back to India. Lisanevich made friends with Prince Emmanuel Golitsyn and in 1944 met and became friends with the Nepalese king Tribhuvan, who was in Calcutta for medical treatment. Lisanevich launched secret meetings of Tribhuvan with Indian prime minister Jawaharlal Nehru and participated in restoring Tribhuvan to power. Lisanevich married a Danish woman, Inger Pheiffer (died in 2013), whom he had met in Bombay. He had three sons with Inger: Mischa, Alexander and Nicholas, and one daughter Xenia from his previous marriage to Kira. In 1951 the king deposed the Rana family from power and invited Boris to Nepal as a tourist. Then he got a job in Nepal where he managed tourism and served as a consultant to the government. The local Soviet embassy asked Lisanevich to organize a meeting for Valentina Tereshkova there.
