The captivating inside story of the man who helmed National Geographic over the course of six decades is a front-row seat to iconic feats of exploration, from the successful hunt for the Titanic to Jane Goodall's field studies, offering a rare portrait of one of the most iconic media empires in history and making an impassioned argument for our enduring need to know and care for our world.Though his career path had been paved by four generations of his family before him, Gilbert M. Grosvenor left his own mark on the National Geographic Society, founded in 1888 and recognised the world over by its ubiquitous yellow border. In an unflinchingly honest memoir as big as the world and all that is in it, Grosvenor shows us what it was like to "grow up Geographic" in a family home where explorers like Robert Peary, Louis Leakey, and Jane Goodall regularly crossed the threshold. As staff photographer, editor in chief and then president of the organisation, Grosvenor oversaw the diversification into television, film, books, as well as its flagship magazine, which under his tenure reached a peak circulation of nearly 11 million. He also narrates the shift from a nonprofit, family-focused enterprise to the more corporate, bottom-line focused world of publishing today.For Grosvenor, running National Geographic wasn't just a job. It was a legacy, motivated by a passion not just to leave the world a better place, but to motivate others to do so, too. Filled with world travel, charismatic explorers, and the complexities of running a publishing empire, A MAN OF THE WORLD is the story of one man, a singular family business, and the changing face of American media.
