A 2022 Choice Reviews Outstanding Academic Title Takes the first in-depth look at the New York City adoption agency that separated twins and triplets in the 1960s, and the controversial and disturbing study that tracked the children’s development while never telling their adoptive parents that they were raising a “singleton twin.” In the early 1960s, the head of a prominent New York City Child Development Center and a psychiatrist from Columbia University launched a study designed to track the development of twins and triplets given up for adoption and raised by different families. The controversial and disturbing catch? None of the adoptive parents had been told that they were raising a twin—the study’s investigators insisted that the separation be kept secret. Here, Nancy Segal reveals the inside stories of the agency that separated the twins, and the collaborating psychiatrists who, along with their cadre of colleagues, observed the twins until they turned twelve. This study, far outside the mainstream of scientific twin research, was not widely known to scholars or the general public until it caught the attention of documentary filmmakers whose recent films, Three Identical Strangers and The Twinning Reaction,left viewers shocked, angered, saddened and wanting to know more. Interviews with colleagues, friends and family members of the agency’s psychiatric consultant and the study’s principal investigator, as well as a former agency administrator, research assistants, journalists, ethicists, attorneys, and—most importantly--the twins and their families who were unwitting participants in this controversial study, are riveting. Through records, letters and other documents, Segal further discloses the investigators’ attempts to engage other agencies in separating twins, their efforts to avoid media exposure, their worries over informed consent issues in the 1970s and the steps taken toward avoiding lawsuits while hoping to enjoy the fruits of publication. Segal's spellbinding stories of the twins’ separation, loss and reunion offers readers the behind-the-scenes details that, until now, have been lost to the archives of history.

When we think of segregation, what often comes to mind is apartheid South Africa, or the American South in the age of Jim Crow—two societies fundamentally premised on the concept of the separation of the races. But as Carl H. Nightingale shows us in this magisterial history, segregation is everywhere, deforming cities and societies worldwide. Starting with segregation’s ancient roots, and what the archaeological evidence reveals about humanity’s long-standing use of urban divisions to reinforce political and economic inequality, Nightingale then moves to the world of European colonialism. It was there, he shows, segregation based on color—and eventually on race—took hold; the British East India Company, for example, split Calcutta into “White Town” and “Black Town.” As we follow Nightingale’s story around the globe, we see that division replicated from Hong Kong to Nairobi, Baltimore to San Francisco, and more. The turn of the twentieth century saw the most aggressive segregation movements yet, as white communities almost everywhere set to rearranging whole cities along racial lines. Nightingale focuses closely on two striking examples: Johannesburg, with its state-sponsored separation, and Chicago, in which the goal of segregation was advanced by the more subtle methods of real estate markets and housing policy. For the first time ever, the majority of humans live in cities, and nearly all those cities bear the scars of segregation. This unprecedented, ambitious history lays bare our troubled past, and sets us on the path to imagining the better, more equal cities of the future.

A leading expert on twins delves into the stories behind her research to reveal the profound joys and real-life traumas of 12 remarkable sets of twins, triplets, and quadruplets. Segal unravels these moving stories with an eye for the challenges that life as a twin (or triplet or quadruplet) can pose to parents, friends, and spouses, as well as the twins themselves.

The key to understanding the current wave of American political division is the attention people pay to politics.

"In Going to Extremes, renowned legal scholar and best-selling author Cass R. Sunstein offers startling insights into why and when people gravitate toward extremism."--Inside jacket.

This definitive analysis of the Lincoln-Douglas debates is “one of the most influential works of American history and political philosophy ever published (National Review). In Crisis of the House Divided, noted conservative scholar and historian Harry V. Jaffa illuminates the political principles that guided Abraham Lincoln from his reentry into politics in 1854 through his Senate campaign against Stephen Douglas in 1858. Through critical analysis of the Lincoln-Douglas debates, Jaffa demonstrates that Lincoln’s political career was grounded in his commitment to constitutionalism, the rule of law, and abolition. A landmark work of American history, it “has shaped the thought of a generation of Abraham Lincoln and Civil War scholars." To mark the fiftieth anniversary of the original publication, Jaffa has provided a new introduction (Civil War History). "A searching and provocative analysis of the issues confronted and the ideas expounded in the great debates…A book which displays such learning and insight that it cannot fail to excite the admiration even of scholars who disagree with its major arguments and conclusions."—D. E. Fehrenbacher, American Historical Review

The Minnesota Study of Twins Reared Apart startled scientists by demonstrating that twins reared apart are as alike, across a number of personality traits and other measures, as those raised together, suggesting that genetic influence is pervasive. Segal offers an overview of the study’s scientific contributions and effect on public consciousness.
