This is an autobiography by the famous trans-himalayan explorer Sven Hedin, a native of Sweden, who has his name written in bold in the role of explorers of central Asia and Tibet. His long career lasted many decades and his pen turned out many classics of exploration like "Trans Himalayan", "Southern Tibet", "Riddles of the Gobi Desert", "Through Asia", "Journey through Persia, Mesopotamia and Caucasus", "Central Asia and Tibet", etcetera. Born in 1865, he commenced his career in 1885-86 when he travelled through Persia and Mesopotamia. Since then he was almost always on expedition, resting of a couple of years to write and then setting off again. He became a Swedish noble in 1902 and was knighted by the English king in 1909. In 1923 he travelled around the world through the United States, Mongolia and Russia. This book is a reprint of the 1929 edition.
