Through the Brazilian Wilderness - Tapa blanda

Roosevelt's popular book Through the Brazilian Wilderness describes his expedition into the Brazilian jungle in 1913 as a member of the Roosevelt-Rondon Scientific Expedition, co-named after its leader, Brazilian explorer Candido Rondon. The book describes the scientific discovery, scenic tropical vistas, and exotic flora and fauna experienced during the adventure. A friend, Father John Augustine Zahm, had searched for new adventures and found them in the forests of South America. After a briefing of several of his own expeditions, he persuaded Roosevelt to commit to such an expedition in 1912. To finance the expedition Roosevelt received support from the American Museum of Natural History, promising to bring back many new animal specimens.

Theodore "T.R." Roosevelt, Jr. (October 27, 1858 – January 6, 1919) was the 26th President of the United States (1901–1909). He is noted for his exuberant personality, range of interests and achievements, and his leadership of the Progressive Movement, as well as his "cowboy" persona and robust masculinity.
