Accidental Brothers

The Story of Twins Exchanged at Birth and the Power of Nature and Nurture

By: Dr. Nancy L. Segal,Yesika S. Montoya

Columbia, 1988. Due to an oversight in a hospital nursery, one twin in each pair of idential twin brothers was switched with a twin in the other pair. Jorge and Carlos were raised in the city of Bogotá; William and Wilber were raised in the rural village of La Paz, 150 miles away. Their parents and siblings were aware of the physical and behavioral differences between the members of each set, but never doubted that the two belonged in their biological families-- until the truth was discovered in 2013. Segal and Montoya examine the power of nature and nurture, and its consequences on our lives. -- adapted from jacket

Deliberately Divided

Inside the Controversial Study of Twins and Triplets Adopted Apart

By: Nancy L. Segal

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.

Born Together—Reared Apart

The Landmark Minnesota Twin Study

By: Nancy L. Segal

The identical “Jim twins” were raised in separate families and met for the first time at age thirty-nine, only to discover that they both suffered tension headaches, bit their fingernails, smoked Salems, enjoyed woodworking, and vacationed on the same Florida beach. This example of the potential power of genetics captured widespread media attention in 1979 and inspired the Minnesota Study of Twins Reared Apart. This landmark investigation into the nature-nurture debate shook the scientific community by demonstrating, across a number of traits, that twins reared separately are as alike as those raised together. As a postdoctoral fellow and then as assistant director of the Minnesota Study, Nancy L. Segal provides an eagerly anticipated overview of its scientific contributions and their effect on public consciousness. The study’s evidence of genetic influence on individual differences in traits such as personality (50%) and intelligence (70%) overturned conventional ideas about parenting and teaching. Treating children differently and nurturing their inherent talents suddenly seemed to be a fairer approach than treating them all the same. Findings of genetic influence on physiological characteristics such as cardiac and immunologic function have led to more targeted approaches to disease prevention and treatment. And indications of a stronger genetic influence on male than female homosexuality have furthered debate regarding sexual orientation.

Someone Else's Twin

The True Story of Babies Switched at Birth

By: Nancy L. Segal

The combination of a riveting true story and cutting-edge twin research makes this book an irresistible page-turner. Identical twins Begoña and Delia were born thirty-eight years ago in Spain’s Canary Islands. Due to chaotic conditions at the hospital or simple human error, the unthinkable happened: Delia was unintentionally switched with another infant in the baby nursery. This fascinating story describes in vivid detail the consequences of this unintentional separation of identical twin sisters. The author considers not only the effects on these particular sisters, but the important implications of this and similar cases for questions concerning identity, familial bonds, nature-nurture, and the law.

Entwined Lives

By: Nancy Segal

Twins are nature's living laboratories. Through them we are able to uncover new information concerning the genetic and environmental factors affecting who we are. Studies using identical and fraternal twins hold the keys to understanding our intellectual abilities, personality traits, social attitudes, and behavior. In Entwined Lives, Dr. Nancy Segal brings together cutting-edge information with illustrative case histories of twins and their families. In addition to the fascinating stories of identical twins reared apart and reunited as adults, Dr. Segal provides insights into the unusual language patterns of twins, how twin studies affect legal decisions, the role of fertility treatments in twin and "twinlike" conceptions, and more. This groundbreaking book explores the ways in which twins enhance our knowledge of human behavioral and physical development, while shedding new light on the nature/nurture debate and on the burgeoning field of evolutionary psychology.

The Twin Children of the Holocaust

Stolen Childhood and the Will to Survive. Photographs from the Twins’ 40th Anniversary Reunion at Auschwitz-Birkenau

By: Nancy L. Segal

This volume is an annotated collection of original, informative, and moving photographs of the twins who survived the brutal medical experiments conducted at the Auschwitz-Birkenau death camp (1943-1945). The experiments were conducted by the infamous physician, Josef Mengele. These never-before-seen photographs were taken by the author (Segal) at the 40th anniversary of the camp’s liberation (January 27, 1985) and the public hearing on Mengele’s crimes at Yad Vashem (Hand and Name) in Jerusalem that followed. Other memorable moments, captured in photographs include traveling to Krakow, visiting Warsaw and hearing survivors’ testimonies. The photographs are organized into ten sections that unfold chronologically—each section is accompanied by a brief essay to provide compelling context and each photograph has an informative caption.
