John Colapinto (born in 1958) is a Canadian journalist, author and novelist and a staff writer at The New Yorker. In 2000, he wrote the New York Times bestseller As Nature Made Him: The Boy Who Was Raised as a Girl, which exposed the details of the David Reimer case, a boy who had undergone a sex change in infancy—a medical experiment long heralded as a success, but which was, in fact, a failure.
