"We've all been taught how genetics got its start in Mendel's pea patch. But the real story is more complicated, and a lot more interesting. In Genetics in the Madhouse, Theodore Porter chronicles some of the early history of heredity--not in gardens, but in asylums. The book is a fascinating exploration of the long-running conviction that madness, criminality, and other mental traits can be passed down from parent to child."--Carl Zimmer, author of She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity

"Porter's masterful book casts the fresh light of sanity over a previously uncharted sea of data on madness. He brings analytical order to an intriguingly chaotic subject, illuminating the challenges of 'big data' from a past era when the plasticity of categorization resulted in data being deduced from conclusions, a problem with uncanny similarities to those we face today."--Stephen M. Stigler, author of The Seven Pillars of Statistical Wisdom

"Important and original. Drawing on a wealth of archival research in many languages across many different national settings, Porter reexamines the role of psychiatry in the study of human heredity. Genetics in the Madhouse is an enormously impressive book."--Andrew Scull, author of Madness in Civilization: A Cultural History of Insanity, from the Bible to Freud, from the Madhouse to Modern Medicine

"A very significant contribution to the history of the human sciences, statistics, and eugenics. Porter rewards readers not only with astonishing insights into nineteenth-century data collection on the mentally ill and feebleminded, but also with the pleasure of reading a good, intriguing story."--Staffan Muller-Wille, coauthor of A Cultural History of Heredity
