The practice of negative racial aspects of eugenics, after World War II, fell within the definition of the new international crime of genocide, set out in the Convention on the Prevention and Punishment of the Crime of Genocide.[9]
The modern field and term were first formulated by Sir Francis Galton in 1883,[10] drawing on the recent work of his half-cousin Charles Darwin.[citation needed] At its peak of popularity eugenics was supported by prominent people, including Margaret Sanger,[11][12] Marie Stopes, H. G. Wells, Woodrow Wilson, Theodore Roosevelt, Emile Zola, George Bernard Shaw, John Maynard Keynes, John Harvey Kellogg, Linus Pauling[13] and Sidney Webb.[14][15][16] Its most infamous proponent and practitioner was however Adolf Hitler who praised and incorporated eugenic ideas in Mein Kampf, and emulated Eugenic legislation for the sterilization of "defectives" that had been pioneered in the United States.[17]
