Or the "Phantom of Fine Hall," a figure many students had seen shuffling around the corridors of the math and physics building wearing purple sneakers and writing numerology treatises on the blackboards. The Phantom was John Nash, one of the most brilliant mathematicians of his generation, who had spiraled into schizophrenia in the 1950s. His most important work had been in game theory, which by the 1980s was underpinning a large part of economics. When the Nobel Prize committee began debating a prize for game theory, Nash's name inevitably came up—only to be dismissed, since the prize clearly could not go to a madman. But in 1994 Nash, in remission from schizophrenia, shared the Nobel Prize in economics for work done some 45 years previously.Economist and journalist Sylvia Nasar has written a biography of Nash that looks at all sides of his life. She gives an intelligent, understandable exposition of his mathematical ideas and a picture of schizophrenia that is evocative but decidedly unromantic. Her story of the machinations behind Nash's Nobel is fascinating and one of very few such accounts available in print (the CIA could learn a thing or two from the Nobel committees).

    The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of Elizebeth Smith who played an integral role in our nation's history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler's Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma--and eventually succeeded, at a terrible cost to his personal life.Fagone unveils America's code-breaking history through the prism of Smith's life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence.

    Eliot's. Now Charles Cross has cracked the code in the definitive biography Heavier Than Heaven, an all-access pass to Cobain's heart and mind. It reveals many secrets, thanks to 400-plus interviews, and even quotes Cobain's diaries and suicide notes and reveals an unreleased Nirvana masterpiece. At last we know how he created, how lies helped him die, how his family and love life entwined his art--plus, what the heck "Smells Like Teen Spirit" really means. (It was graffiti by Bikini Kill's Kathleen Hanna after a double date with Dave Grohl, Cobain, and the "over-bored and self-assured" Tobi Vail, who wore Teen Spirit perfume; Hanna wrote it to taunt the emotionally clingy Cobain for wearing Vail's scent after sex--a violation of the no-strings-attached dating ethos of the Olympia, Washington, "outcast teen" underground. Cobain's stomach-churning passion for Vail erupted in six or so hit tunes like "Aneurysm" and "Drain You.") Cross uncovers plenty of news, mostly grim and gripping. As a teen, Cobain said he had "suicide genes," and his clan was peculiarly defiant: one of his suicidal relatives stabbed his own belly in front of his family, then ripped apart the wound in the hospital. Cobain was contradictory: a sweet, popular teen athlete and sinister berserker, a kid who rescued injured pigeons and laughingly killed a cat, a talented yet astoundingly morbid visual artist. He grew up to be a millionaire who slept in cars (and stole one), a fiercely loyal man who ruthlessly screwed his oldest, best friends. In fact, his essence was contradictions barely contained. Cross, the coauthor of Nevermind: Nirvana, the definitive book about the making of the classic album, puts numerous Cobain-generated myths to rest. (Cobain never lived under a bridge--that Aberdeen bridge immortalized in the 12th song on Nevermind was a tidal slough, so nobody could sleep under it.) He gives the fullest account yet of what it was like to be, or love, Kurt Cobain. Heavier Than Heaven outshines the also indispensable Come As You Are. It's the deepest book about pop's darkest falling star. --Tim Appelo

    Britain is at war. The horrors of blitzkrieg have seen one western European democracy after another fall in rapid succession to Nazi boot and shell. Invasion seems mere hours away. Just days after becoming Prime Minister, Winston Churchill must deal with this horror—as well as a skeptical King, a party plotting against him, and an unprepared public. Pen in hand and typist-secretary at the ready, how could he change the mood and shore up the will of a nervous people? In this gripping day-by-day, often hour-by-hour account of how an often uncertain Churchill turned Britain around, the celebrated Bafta-winning writer Anthony McCarten exposes sides of the great man never seen before. He reveals how he practiced and re-wrote his key speeches, from ‘Blood, toil, tears and sweat’ to ‘We shall fight on the beaches’; his consideration of a peace treaty with Nazi Germany, and his underappreciated role in the Dunkirk evacuation; and, above all, how 25 days helped make one man an icon. Using new archive material, McCarten reveals the crucial behind-the-scenes moments that changed the course of history. It’s a scarier—and more human—story than has ever been told. “McCarten's pulse-pounding narrative transports the reader to those springtime weeks in 1940 when the fate of the world rested on the shoulders of Winston Churchill. A true story thrillingly told. Thoroughly researched and compulsively readable.”—Michael F. Bishop, Executive Director of the International Churchill Society
