    Through its unparalleled research, exploration, publications, and photography, the organization and its magazine have, in many ways, defined how we see the world. Now Robert Poole's Explorers House gives a vibrant, behind-the-scenes look at National Geographic, from its start in 1888 to its evolution into one of the most esteemed and iconic American institutions. The story of the National Geographic is a family story of a media dynasty to rival the Sulzbergers or Luces. The Grosvenors, along with Alexander Graham Bell, who was linked to the family by marriage, created the institution's photography-based monthly, and the family has been on the masthead since the McKinley administration. Content to stay in the shadows, however, they have remained modestly obscured from public view while their media empire has grown to reach some forty million readers and viewers each month. The Grosvenor and Bell family history is not merely the story of the National Geographic; it is a captivating view of the sweep of American scientific, geographic, and political history since the late nineteenth century, rendered in fascinating human terms by Poole. Moreover, Explorers House shows the inside workings of the magazine's editorial process, providing an unprecedented look behind some of National Geographic's ground-breaking articles and explorations-from Cousteau's famous Calypso voyages to the origins of Jane Goodall's research on chimpanzees to the institution's 1963 Mt. Everest expedition, the first to place an American on the summit. We also hear of the writers and photographers who are larger than life figures themselves, such as Luis Marden, the writer-photographer who unearthed the remains of the H.M.S. Bounty off Pitcairn Island, among many other feats. Explorers House presents the National Geographic from the inside out-from its remarkable founding family to the very ends of the earth it investigates.

    His invention of the first practical incandescent lamp 140 years ago so dazzled the world--already reeling from his invention of the phonograph and dozens of other revolutionary devices--that it cast a shadow over his later achievements. In all, this near-deaf genius ("I haven't heard a bird sing since I was twelve years old") patented 1,093 inventions, not including others, such as the X-ray fluoroscope, that he left unlicensed for the benefit of medicine.One of the achievements of this staggering new biography, the first major life of Edison in more than twenty years, is that it portrays the unknown Edison--the philosopher, the futurist, the chemist, the botanist, the wartime defense adviser, the founder of nearly 250 companies--as fully as it deconstructs the Edison of mythological memory. Edmund Morris, winner of the Pulitzer Prize and the National Book Award, brings to the task all the interpretive acuity and literary elegance that distinguished his previous biographies of Theodore Roosevelt, Ronald Reagan, and Ludwig van Beethoven. A trained musician, Morris is especially well equipped to recount Edison's fifty-year obsession with recording technology and his pioneering advances in the synchronization of movies and sound. Morris sweeps aside conspiratorial theories positing an enmity between Edison and Nikola Tesla and presents proof of their mutually admiring, if wary, relationship.Enlightened by seven years of research among the five million pages of original documents preserved in Edison's huge laboratory at West Orange, New Jersey, and privileged access to family papers still held in trust, Morris is also able to bring his subject to life on the page--the adored yet autocratic and often neglectful husband of two wives and father of six children. If the great man who emerges from it is less a sentimental hero than an overwhelming force of nature, driven onward by compulsive creativity, then Edison is at last getting his biographical due.
