Ron Chernow tells the story of a man who overcame all odds to shape, inspire, and scandalize the newborn America. Few figures in American history have been more hotly debated or more grossly misunderstood than Alexander Hamilton. Chernow's biography argues that the political and economic greatness of today's America is the result of Hamilton's countless sacrifices to champion ideas that were often wildly disputed during his time. Chernow here recounts Hamilton's turbulent life: an illegitimate, largely self-taught orphan from the Caribbean, he came out of nowhere to take America by storm, rising to become George Washington's aide-de-camp in the Continental Army, coauthoring The Federalist Papers, founding the Bank of New York, leading the Federalist Party, and becoming the first Treasury Secretary of the United States. Historians have long told the story of America's birth as the triumph of Jefferson's democratic ideals over the aristocratic intentions of Hamilton. Chernow presents an entirely different man, whose legendary ambitions were motivated not merely by self-interest but by passionate patriotism and a stubborn will to build the foundations of American prosperity and power. His is a Hamilton far more human than we've encountered before -- from his shame about his birth to his fiery aspirations, from his intimate relationships with childhood friends to his titanic feuds with Jefferson, Madison, Adams, Monroe, and Burr, and from his highly public affair with Maria Reynolds to his loving marriage to his loyal wife Eliza. And never before has there been a more vivid account of Hamilton's famous and mysterious death in a duel with Aaron Burr in July of 1804.

"When Bernie Sanders began his race for the presidency, it was considered by the political establishment and the media to be a "fringe" campaign, something not to be taken seriously. After all, he was just an independent senator from a small state with little name recognition. His campaign had no money, no political organization, and it was taking on the entire Democratic Party establishment. By the time Sanders's campaign came to a close, however, it was clear that the pundits had gotten it wrong. Bernie had run one of the most consequential campaigns in the modern history of the country. He had received more than 13 million votes in primaries and caucuses throughout the country, won twenty-two states, and more than 1.4 million people had attended his public meetings. Most important, he showed that the American people were prepared to take on the greed and irresponsibility of corporate America and the 1 percent. In Our Revolution, Sanders shares his personal experiences from the campaign trail, recounting the details of his historic primary fight and the people who made it possible. And for the millions looking to continue the political revolution, he outlines a progressive economic, environmental, racial, and social justice agenda that will create jobs, raise wages, protect the environment, and provide health care for all--and ultimately transform our country and our world for the better. For him, the political revolution has just started. The campaign may be over, but the struggle goes on"--Provided by publisher.

The bestselling classic that examines the history of economic thought from Adam Smith to Karl Marx—“all the economic lore most general readers conceivably could want to know, served up with a flourish” ( The New York Times ). The Worldly Philosophers not only enables us to see more deeply into our history but helps us better understand our own times. In this seventh edition, Robert L. Heilbroner provides a new theme that connects thinkers as diverse as Adam Smith and Karl Marx. The theme is the common focus of their highly varied ideas—namely, the search to understand how a capitalist society works. It is a focus never more needed than in this age of confusing economic headlines. In a bold new concluding chapter entitled “The End of the Worldly Philosophy?” Heilbroner reminds us that the word “end” refers to both the purpose and limits of economics. This chapter conveys a concern that today’s increasingly “scientific” economics may overlook fundamental social and political issues that are central to economics. Thus, unlike its predecessors, this new edition provides not just an indispensable illumination of our past but a call to action for our future.

From the Pulitzer Prize–winning bestselling author of Alexander Hamilton , the inspiration for the hit Broadway musical, comes this definitive biography of the Warburgs, one of the great German-Jewish banking families of the twentieth century. Bankers, philanthropists, scholars, socialites, artists, and politicians, the Warburgs stood at the pinnacle of German (and, later, of German-American) Jewry. They forged economic dynasties, built mansions and estates, assembled libraries, endowed charities, and advised a German kaiser and two American presidents. But their very success made the Warburgs lightning rods for anti-Semitism, and their sense of patriotism became increasingly dangerous in a Germany that had declared Jews the enemy. Ron Chernow's hugely fascinating history is a group portrait of a clan whose members were renowned for their brilliance, culture, and personal energy yet tragically vulnerable to the dark and irrational currents of the twentieth century.

A journey into the glittering, surreal heart of 21st century Russia: into the lives of Hells Angels convinced they are messiahs, professional killers with the souls of artists, bohemian theatre directors turned Kremlin puppet-masters, supermodel sects, post-modern dictators and oligarch revolutionaries. This is a world erupting with new money and new power, changing so fast it breaks all sense of reality, where life is seen as a whirling, glamorous masquerade where identities can be switched and all values are changeable. It is home to a new form of authoritarianism, far subtler than 20th century strains, and which is rapidly expanding to challenge the global order. An extraordinary book - one which is as powerful and entertaining as it is troubling - Nothing is True and Everything is Possible offers a wild ride into this political and ethical vacuum

And no scholar of contemporary East Asian history and culture is better qualified than Ezra Vogel to disentangle the many contradictions embodied in the life and legacy of China’s boldest strategist. Once described by Mao Zedong as a “needle inside a ball of cotton,” Deng was the pragmatic yet disciplined driving force behind China’s radical transformation in the late twentieth century. He confronted the damage wrought by the Cultural Revolution, dissolved Mao’s cult of personality, and loosened the economic and social policies that had stunted China’s growth. Obsessed with modernization and technology, Deng opened trade relations with the West, which lifted hundreds of millions of his countrymen out of poverty. Yet at the same time he answered to his authoritarian roots, most notably when he ordered the crackdown in June 1989 at Tiananmen Square. Deng’s youthful commitment to the Communist Party was cemented in Paris in the early 1920s, among a group of Chinese student-workers that also included Zhou Enlai. Deng returned home in 1927 to join the Chinese Revolution on the ground floor. In the fifty years of his tumultuous rise to power, he endured accusations, purges, and even exile before becoming China’s preeminent leader from 1978 to 1989 and again in 1992. When he reached the top, Deng saw an opportunity to creatively destroy much of the economic system he had helped build for five decades as a loyal follower of Mao—and he did not hesitate.

The incredible true account of Kamila Sidiqi who, when her father and brother were forced to flee Kabul, became the sole breadwinner for her five siblings. Armed only with grit and determination, she picked up a needle and thread and created a thriving business of her own and held her family together.

The veteran political journalist and New York Times bestselling author goes behind the scenes at the White House to recount the dramatic tale of a pivotal period in the Obama presidency, from the game-changing 2010 midterm elections to the beginning of the critical 2012 campaign season—a tumultuous time that tested the president as never before and set the stage for a titanic clash over the future of the nation After Barack Obama's first two years as president—during which he navigated the United States through its severest economic crisis since the Great Depression while managing wars in Afghanistan and Iraq—he was faced with a bitterly divided nation and an emboldened political opposition dedicated to impeding his presidency. What followed was a year of political crises and fierce battles that would transform Obama and profoundly shape the terrain for the next election. In Showdown , astute political journalist David Corn chronicles and examines this crucial time in the Obama presidency and its impact on the nation's future. Drawing on interviews with White House officials, Obama's inner circle, members of Congress, and others, Corn takes the reader into the Oval Office and the back rooms on Capitol Hill for a fast-paced and gripping account of the major events as they unfolded: the controversial tax-cut deal with Congress in December 2010; the repeal of Don't Ask/Don't Tell; the passage of the New START treaty; the near shutdown of the government in early 2011; the revolutionary Arab spring; the killing of Osama bin Laden; the intense, high-wire debt-ceiling negotiations (in which intransigent House Republicans risked the nation's financial standing); House Speaker John Boehner's erratic maneuvers during the rise and fall of the grand bargain; and the face-off between Obama and congressional Republicans over how best to create jobs. Corn captures the dilemmas faced by a president assailed by disappointed progressives and defiantly obstructionist Republicans determined to see his defeat. Here is a chief executive trying to balance the cross-cutting demands of governance and politics while handling unending challenges at home and abroad. The book reveals a thoughtful leader with a cool head who is unafraid to take risks and make tough choices, a steely battler who successfully turned his enemies' obstinacy to his advantage. Obama has often frustrated supporters, but Corn shows how the president, who often puts pragmatism ahead of partisan demands, has craftily operated within a hostile conservative political climate, looking to win the long game, achieve progressive goals, and, ultimately, win reelection. A vivid and powerful account of White House decision-making, Showdown offers a unique and enlightening look at the turbulent American political scene during one of the most consequential moments of the nation's history, and explains the fascinating and complicated leader at the heart of this vortex.

Christopher Columbus's 1492 voyage across the Atlantic Ocean in search of a trading route to China, and his unexpected landfall in the Americas, is a watershed event in world history. Yet Columbus made three more voyages within the span of only a decade, each designed to demonstrate that he could sail to China within a matter of weeks and convert those he found there to Christianity. These later voyages were even more adventurous, violent, and ambiguous, but they revealed Columbus's uncanny sense of the sea, his mingled brilliance and delusion, and his superb navigational skills. In all these exploits he almost never lost a sailor. By their conclusion, however, Columbus was broken in body and spirit. If the first voyage illustrates the rewards of exploration, the latter voyages illustrate the tragic costs, political, moral, and economic. In this book the author re-creates each of these adventures as well as the historical background of Columbus's celebrated, controversial career.

From Pulitzer-Prize-nominated author Susan Griffin comes an unprecedented, provocative look at the dazzling world of the West’s first independent women, whose lively liaisons brought them unspoken influence, wealth, and freedom. While they charmed some of Europe’s most illustrious men honing their social skills as well as their sexual ones, the great courtesans gained riches, power, education, and sexual freedom in a time when other women were denied all of these. From Imperia of sixteenth-century Rome, who personified the Renaissance ideal of beauty; Mme. de Pompadour, the arbiter of all things fashionable in eighteenth-century Paris and Versailles; Liane de Pougy, known in France during the Belle Epoque as “Our National Courtesan”; to Sarah Bernhardt, who, following in her mother’s footsteps, supported herself in her early career with a second profession, The Book of the Courtesans tells the life stories and intricacies of the lavish lifestyles of these women. Unlike their geisha counterparts, courtesans neither lived in brothels nor bent their wills to suit their suitors. They were strong- willed, autonomous, and plucky. An open secret, their presence can be felt throughout our culture. The muses who enflamed the hearts and imaginations of our most celebrated artists, they were also artists in their own right. They wrote poetry and novels, invented the cancan at the Moulin Rouge, and presented celebrated acts at the Folies Bergères. They helped to influence and shape the sensibility of modern literature, painting, and fashion. When Greek sculptor Praxiteles wanted to depict Venus he used a famous courtesan as a model, as in later centuries Titian, Veronese, Raphael, Giorgione, and Boucher did when they painted goddesses. When Marcel Proust was a young man it was the courtesan Laure Hayman who took him under her wing, introducing him to the right people, and providing inspiration for one of literature’s greatest masterpieces. And they often had considerable political influence too. When King Louis XV needed advice on foreign affairs or appointments of state he turned to Jeanne du Barry as well as Pompadour. In her witty and insightful prose, as Griffin celebrates these alluring and fascinating women, she restores a lost legacy of women’s history. She gives us the stories of these amazing women who, starting from impoverished or unimpressive beginnings, garnered chateaux, fine coaches, fabulous collections of jewelry, and even aristocratic titles along the way. And through a brilliant exploration of their extraordinary abilities, skills, and talents which Griffin playfully categorizes as their virtues "Timing, Beauty, Cheek, Brilliance, Gaiety, Grace, and Charm" her book explains how, while helping themselves, through their often outrageous, always entertaining examples, the great courtesans not only enriched our cultural heritage but helped to liberate women from the social, sexual, and economic strictures that confined them. Intensively researched and beautifully crafted, The Book of the Courtesans delves into scintillating but often hidden worlds, telling stories gleaned from many sources, including courtesans’ memoirs, presented along with stunning rare photographs to create memorable portraits of some of the most pivotal figures in women’s history.

Filling a remarkable gap, Alan Schom, an acclaimed historian, scholar and author, offers the most complete picture ever of Napoleon Bonaparte, "the scourge of Europe" and France's greatest hero. Based on more than 10 years of exhaustive research, Schom illuminates Napoleon's important economic and social reforms, his reorganization of the French government and his tempestuous personal life and its effect on his political decisions. Remarkably ambitious and compulsively readable, Napoleon Bonaparte covers every aspect of l'Empereur's life and career -- from his childhood on Corsica to his dramatic rise to the throne of France; from his campaigns of conquest to his final crushing defeat at Waterloo and death in exile on St. Helena. A lively and accessible text, Schom's book is generously illustrated with halftones and maps and features startling new insights about Napoleon's key aides, ministers and generals. Schom portrays Napoleon with candor, exalting his ambition and undeniable genius, but also addressing his dark side -- his ego, his failures and frailties, and the misery caused by his years of warfare across Europe. Powerful, dramatic, colorful and impossible to put down, Napoleon Bonaparte is a biography as complex, challenging and fascinating as the legend himself.

"The definitive history of the Carter Administration from the man who participated in its surprising number of accomplishments--drawing on his extensive and never-before-seen notes. Stuart Eizenstat was at Jimmy Carter's side from his political rise in Georgia through four years in the White House, where he served as Chief Domestic Policy Adviser. He was directly involved in all domestic and economic decisions as well as in many foreign policy ones. Famous for the legal pads he took to every meeting, he draws on more than 5000 pages of contemporaneous notes as well as declassified documents and more than 350 interviews of all the major figures of the time, to write this comprehensive history of an underappreciated president--and to give an intimate view on how the presidency works. Eizenstat reveals the grueling negotiations behind Carter's peace between Israel and Egypt, what led to the return of the Panama Canal, and how Carter made human rights a presidential imperative. He follows Carter's passing of America's first comprehensive energy policy, and his deregulation of the oil, gas, transportation, and communications industries. And he details the creation of the modern vice-presidency. Eizenstat also details Carter's many missteps, including the Iranian Hostage Crisis, because Carter's desire to do the right thing, not the political thing, often hurt him and alienated Congress. His willingness to tackle intractable problems, however, led to major, long-lasting accomplishments. This major work of history shows first-hand where Carter succeeded, where he failed, and how he set up many successes of later presidents"--

In Two Lucky People , Rose and Milton Friedman provide a memorable and lively account of their lives, the people they knew, and the work they shared. Their involvement with world leaders and many of this century's most important public policy issues moves their memoir beyond the merely personal and makes fascinating reading for anyone interested in the history of twentieth-century ideas. "The Friedmans come across as the last Enlightenment thinkers in a post-modern world. . . . This is a book that restores your faith in reasoned discourse. . . . There really are people who believe in scholarly exchange as a way to discover truth."—David Brooks, New York Times Book Review "The Friedmans are a feisty couple, who clearly delight in their lives and each other. And shining through their reticence, and their conservatism, is a decency that even liberals will recognize."—Milton and Judith Viorst, Washington Post Book World "This engaging book recounts the life and contributions of one of America's most influential writers and economists in the second half of the twentieth century. And her husband's no slouch either. . . . An indispensable guide through the evolution of economic thought."—Stephen Moore, National Review "A thought-provoking book and one rich in history, the personal history of the Friedmans . . . and the cultural and political history of our country."—Steve Huntley, Chicago Sun-Times Books "[ Two Lucky People ] is almost like a letter from a couple of old friends—a couple of old friends who had a long, compelling intellectual journey, came to know some of the great world leaders of this century, and had 60 years of happy, supportive marriage."—N. Gregory Mankiw, Fortune "A rich autobiographical and historical panorama."—William P. Kucewicz, Wall Street Journal

The Cruel Years provides readers with a vivid picture of what life was like a hundred years ago, not for the rich and famous but for ordinary working Americans. The story is told in the words of twenty-two fascinating people who lived by laboring long hours at farms and factories and mines. A preface by Howard Zinn and an introduction by William Loren Katz provide an easy-to-follow historical map that places these hard-hitting, first-person narratives in the context of their troubled times and within the larger picture of U.S. growth and development. Here are the no-nonsense words of a young immigrant trying to survive as a sweatshop operator in New York City, a hard working farmer's wife who has writing ambitions; a black southern sharecropper seeking fulfillment under a new system of slavery; a young Puerto Rican passing the Statue of Liberty and ready for new challenges; a Chinese immigrant, a Mexican immigrant, and a Japanese immigrant struggling to rise from lower rungs on the social and economic ladder; an Irish girl of sixteen deciding to become a political agitator; a black southern woman trying to fend off the hurts of Jim Crow; a coal miner telling of the lethal dangers of his work; and a black cowhand rejoicing in the thrill of the cattle trails.

Father of the birth control pill, developer of antihistamines, founder of biomedical companies, teacher of world-class chemists, best-selling novelist.... As The Scientist notes, "Few can match Carl Djerassi's juggling act for success and longevity". Here is Djerassi's remarkable autobiography. Blending vivid descriptions of the lucrative world of drug development with controversial chapters on the politics of contraception and poignant disclosures about his personal life, this book tells the story of one of the most productive and socially conscious chemists working today. The Pill, Pygmy Chimps, and Degas' Horse tells how Djerassi, while still in his twenties and leading a small team in an obscure laboratory in Mexico City, used a locally grown yam first to synthesize cortisone and then, within twelve months, to create the first steroid effective as a birth control pill. Dubbed for this latter work "the father of the pill", a title he often shares with Gregory Pincus and John Rock, who performed the biological and clinical studies to confirm the pill's efficacy in humans, Djerassi has spent a lifetime thinking and rethinking, discussing and debating, the social, economic, and biological consequences of the changed attitudes toward contraception engendered by the pill. In two riveting chapters entitled "The Pill at Twenty" and "The Pill at Forty: What Now?" Djerassi recounts the fascinating history of the pill's journey from its first days in the laboratory to widespread public use--from being hailed as an agent of the sexual revolution to condemnation as an agent of the new promiscuity, to being accused of being an expression of the scientific community's sexism (Why was there no malebirth control pill?). And then, in a powerful consideration of where the politics of contraception have taken us, he discusses why so few innovations in contraception are being investigated today, and why even fewer are making their way to the public. The Pill, Pygmy Chimps, and Degas' Horse chronicles Djerassi's many successful careers in science, business, the academy, and the arts (he is a published poet and novelist, as well as the founder of an artists' colony). His growing appreciation for the soft side of science--its human and humane aspects--have long been reflected in the courses he teaches at Stanford, in the plot of his novel, Cantor's Dilemma, and in his decision to found one of the first environmentally aware pesticide companies. In this intellectually challenging book, the reader is let into the fertile mind and psyche of one of the few Renaissance men of twentieth-century science.

In this book, Rudolf A. Raff reaches out to the scientifically queasy, using his life story and his growth as a scientist to illustrate why science matters, especially at a time when many Americans are both suspicious of science and hostile to scientific ways of thinking. Noting that science has too often been the object of controversy in school curriculums and debates on public policy issues ranging from energy and conservation to stem-cell research and climate change, Raff argues that when the public is confused or ill-informed, these issues tend to be decided on religious, economic, and political grounds that disregard the realities of the natural world. Speaking up for science and scientific literacy, Raff tells how and why he became an evolutionary biologist and describes some of the vibrant and living science of evolution. Once We All Had Gills is also the story of evolution writ large: its history, how it is studied, what it means, and why it has become a useful target in a cultural war against rational thought and the idea of a secular, religiously tolerant nation.

"THE PURPOSE OF POLITICS IS NOT TO DEFEAT YOUR OPPONENT AS MUCH AS IT IS TO PROVIDE SUPERIOR LEADERSHIP AND BETTER IDEAS THAN THE OPPOSITION." --JACK KEMP The late 1970s were miserable for America. It was the post-Vietnam, post-Watergate era, a time of high unemployment, ruinous inflation, gasoline lines, Communist advances, and bottomed-out U.S. morale. In the 1980s, it all turned around: "stagflation" ended and nearly two decades of prosperity ensued. The Soviet Union retreated, then collapsed. America again believed in itself. And around the world, democratic capitalism was deemed "the end of history." Ronald Reagan's policies sparked the American renaissance, but the Gipper's leadership is only part of the story. The economic theory that underpinned America's success was pioneered by a star professional quarterback turned self-taught intellectual and "bleeding-heart conservative": Jack Kemp. Kemp's role in a pivotal period in American history is at last illuminated in this first-ever biography, which also has lessons for the politics of today. Kemp was the congressional champion of supply-side economics--the idea that lowering taxes would foster growth. Even today, almost no one advocates a return to a top income tax rate of 70 percent. Kemp didn't just challenge the Democratic establishment. He also encouraged his fellow Republicans to be growth (not austerity) minded, open their tent to minorities and blue-collar workers, battle poverty and discrimination, and once again become "the party of Lincoln." Kemp approached politics the same way he played quarterback for the Buffalo Bills: with a refusal to accept defeat. Yet he also was incapable of personal attack, arguing always on the level of ideas. He regarded opponents as adversaries, not enemies, and often cooperated with them to get things done. Despite many ups and downs, including failed presidential and vice-presidential bids, he represented a positive, idealistic, compassionate Republicanism. Drawing on never-published papers and more than one hundred Kemp Oral History Project interviews, noted journalists Morton Kondracke and Fred Barnes trace Kemp's life, from his childhood through his pro football career to his influential years as a congressman and cabinet secretary. As the American Dream seems to be waning and polarized politics stifles Washington, Kemp is a model for what politics ought to be. The Republican party and the nation are in desperate need of another Kemp.

A personal and insightful call to action and a much-needed book about one of the most important bilateral relationships in the world—the relationship between Canada and the US—and why diplomacy matters now more than ever before. All over the world, diplomacy is under threat. Diplomats used to handle sensitive international negotiations, but increasingly, incendiary Tweets and bombastic public statements are posing a threat to foreign relations. In The Art of Diplomacy , the former US ambassador to Canada, Bruce Heyman, and his partner, Vicki Heyman, spell out why diplomacy and diplomats matter, especially in today’s turbulent times. This dynamic power couple arrived in Canada intent on representing American interests, but they quickly learned that to do so meant representing the shared interests of all citizens—no matter what side of the 49th parallel they happened to live on. Bruce and Vicki narrate their three years in Canada spent journeying across the country and meeting Canadians from all walks of life—including Supreme Court justices, prime ministers, fishermen, farmers, artists, and entrepreneurs. They tell the behind-the-scenes stories of how their team helped bring Obama to Canada and Trudeau to the US. They also reveal the importance of creating cultural and artistic exchange between Canada and the US, of promoting economic and trade interests, and overall, of making a lasting positive impact on one of the most important relationships in the free world today. This politically poignant and heartfelt memoir is a call to action, a reminder that only by working together to protect our shared values—the environment, social justice and human rights—can nations build a better world for all. As their long-time friend and colleague President Obama once said, “The world needs more Canada.” At this key moment in history, when opposing nationalist and populist agendas threaten to divide us, The Art of Diplomacy reminds us to keep calm, to work together and to carry on.

Hungary's War of Independence was the bloodiest conflict of the European revolutionary era, exciting nationalist passions that burn hot till this day. The story of this dramatic time unfolds through the towering personality of Louis Kossuth--a principal actor in the dramatic events. He and his fellow noblemen sized the opportunity offered by the continent's upheavals to restore Hungary's sovereignty under the Habsburg Crown. They introduced many administrative, social, and economic reforms...only to run into the opposition of many of the country's most powerful forces. In 1949, Kossuth fled--never to return home again.

Son of pioneer movie producer Harry Rapf, Maurice Rapf grew up in Hollywood in that city's golden age. After moving from independent filmmaking to Warner Bros., in 1924 the senior Rapf joined Louis Mayer and became one of the founding members of MGM. Hence, movies were a huge influence in Maurice Rapf's early life. After graduating from college, Rapf worked as a screenwriter for major Hollywood studios, but, in 1947, he left Hollywood, never to work for a major studio again. On numerous occasions, he was called before the House Un-American Activities Committee as an alleged communist, although he never made a public confession or denial. As a result he was blacklisted from the industry and forced to begin a new career in the East. He eventually became a movie critic and film studies professor. Maurice Rapf knows movies and the movie business as an insider, from first-hand experience, not from books. His autobiography is the story of one person's interaction with an evolving Hollywood. Rapf witnessed the historical progression of movie production: from silents to sound, from a fun-loving frontier community to a huge and fiercely competitive industry, from an apolitical never-never land to a community very much aware of-and nervous about-its social responsibility in a period of economic depression and in a period of world peace seriously threatened by the aggression of fascism. Of interest to students and teachers of film studies, of American history, and of American popular culture, as well as anyone who loves movies.
