20th century In 1913 British explorers Frederick Bailey and Henry Morshead had carried out an unauthorised exploration of Tsangpo Gorge and later Tibet officially agreed to the 1921 British Mount Everest reconnaissance expedition and the 1935 reconnaissance expedition although they both carried out exploration well beyond the terms of their permits. In 1938-1939 from May 1938 to August 1939, a German scientific expedition led by German zoologist and SS officer Ernst Schäfer was carried out. Member of this expedition was also Bruno Beger, a racial anthropologist, ethnologist, and explorer. In 2009, 5.6 million tourists visited Tibet Autonomous Region and spent ¥5.6 billion. Both were 150% increases from 2008. References Bibliography Bernbaum, Edwin: The Way to Shambhala, Reprint: (1989). Jeremy P. Tarcher, Inc., Los Angeles. Das, Sarat Chandra.
