For more than fifty years, George Schaller has been on a mis­sion: to save the world’s great wild beasts. From enthu­si­as­tic stu­dent spot­ting his first griz­zly in Alas­ka, to pio­neer­ing field biol­o­gist radio-tag­ging lions in the Serengeti, to world-renowned con­ser­va­tion­ist cam­paign­ing for nature reserves in Chi­na, George Schaller has been an inspi­ra­tion an entire gen­er­a­tion of sci­en­tists and explor­ers. Packed with intrigu­ing sci­ence and the thrill of dis­cov­ery, here is a biog­ra­phy that bril­liant­ly cap­tions the spir­it and pas­sion of an extra­or­di­nary life in the wild.
