This family is known for being the subject of HH G. Goddard's research into the hereditary nature of mental retardation and antisocial behavior in 1912. Kallikak (a pseudonym) was a British aristocrat who participated in the American War of Independence and had an illegitimate child with a mentally retarded woman. Over the next five generations, 480 descendants were born to this family. Of the 189 people who could be surveyed, 143 (75.7%) were mentally retarded, alcoholics, or criminals, and only 46 were normal. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
