NEW YORK TIMES BESTSELLER “We should aspire to Colapinto's stellar journalist example: listening carefully to the circumstances of those who are different rather than demanding that they conform to our own.” — Washington Post The true story about the "twins case" and a riveting exploration of medical arrogance, misguided science, societal confusion, gender differences, and one man's ultimate triumph In 1967, after a twin baby boy suffered a botched circumcision, his family agreed to a radical treatment that would alter his gender. The case would become one of the most famous in modern medicine—and a total failure. The boy's uninjured brother, raised as a boy, provided to the experiment the perfect matched control.  As Nature Made Him tells the extraordinary story of David Reimer, who, when finally informed of his medical history, made the decision to live as a male. Writing with uncommon intelligence, insight, and compassion, John Colapinto sets the historical and medical context for the case, exposing the thirty-year-long scientific feud between Dr. John Money and his fellow sex researcher, Dr. Milton Diamond—a rivalry over the nature/nurture debate whose very bitterness finally brought the truth to light.  A macabre tale of medical arrogance, it is first and foremost a human drama of one man's—and one family's—amazing survival in the face of terrible odds. This landmark work of investigative journalism reveals: A Landmark Medical Experiment: How a botched circumcision on an infant boy led Dr. John Money of Johns Hopkins to attempt the first-ever sex reassignment on a developmentally normal child. - The Ultimate Test of Nature vs. Nurture: With his identical twin brother providing a perfect genetic control, David Reimer’s case provided a unique, real-world battleground for one of science’s oldest debates. - A Question of Medical Ethics: An unflinching look at a thirty-year scientific feud, the suppression of inconvenient data, and the devastating human cost of a failed theory. - The Boy Who Knew: The powerful and triumphant story of David Reimer’s lifelong struggle, his refusal to accept an identity that felt wrong, and his courageous decision to reclaim his life as a male. "A page-turning story of heroes and villains that stirs both compassion and anger." - Philadelphia Inquirer "A riveting account of medical arrogance and misguided science." - Playboy "Colapinto's account . . . raises fascinating scientific, philosophical, and ethical questions—and also packs an irresistible narrative force from start to finish. - Providence Phoenix "Colapinto's book is a stinging and overdue indictment of the 'sexual reassignment' of infants like baby Bruce and those born with both male and female sex organs....The book also serves as an intimate, heartbreaking diary of Bruce Brenda Reimer, the casualty of a ghoulish science project gone terribly wrong." - Cleveland Plain Dealer "Colapinto, a writer of striking lucidity and compassion, inspired the very private man who now proudly calls himself David to reveal the entire story of his horrendous ordeal in hopes of preventing others from suffering his fate. The result is an arresting and invaluable narrative of personal tragedy, scientific arrogance, and societal confusion over the source and significance of gender differences." - Booklist "For the most part, As Nature Made Him is a story of innocence stolen, and of ill fate bravely born....But the book is also a testament to the immutability of self. Because David in the end is a triumph." - Dallas Morning News "In the end, what makes As Nature Made Him impossible to put down is not the machinations of a misguided scientist but the suffering, courage and ultimate triumph of a truly unfortunate child." - Psychology Today "Raises fascinating scientific, philosophical questions--and also packs an irresistible narrative force from start to finish" - Boston Phoenix "This thoroughly researched and skillfully told profile of David Reimer deserves to be an early candidate for the best nonfiction book of the year." - Albany Times Union "What happened to Bruce and his parents is a true-life medical horror to rival any of Robin Cook's science thrillers...a fascinating book." - Houston Chronicle “Ultimately, the book stands as a passionate warning against social pressure and prejudice'whether medical, ideological or biological. As a society, we should aspire to Colapinto's stellar journalist example: listening carefully to the circumstances of those who are different rather than demanding that they conform to our own.” - Washington Post “With remarkable concision, Mr. Colapinto has telescoped this medical scandal, brilliantly weaving the perspectives of David [Reimer], his family, friends, doctors, and wife...The book's structure is that of a mystery.” - New York Observer In 1967, after a twin baby boy suffered a botched circumcision, his family agreed to a radical treatment that would alter his gender.
