In War Against the Weak, award-winning investigative journalist Edwin Black connects the crimes of the Nazis to a pseudoscientific American movement of the early 20th century called eugenics. Based on selective breeding of human beings, eugenics began in laboratories on Long Island but ended in the concentration camps of Nazi Germany. Cruel and racist laws were enacted in 27 U.S. states, and the supporters of eugenics included progressive thinkers like Woodrow Wilson, Margaret Sanger, and Oliver Wendell Holmes. Ultimately, over 60,000 'unfit' Americans were coercively sterilized, a third of them after Nuremberg declared such practices crimes against humanity. This is a timely and shocking chronicle of bad science at its worst —: with many important lessons for the impending genetic age.
