Henry Goddard's The Kallikak Family
Henry Goddard was a prominent and pioneering psychologist and educator in the early twentieth century. From 1906 to 1918 Goddard was the Director of Research at New Jersey’s Vineland Training School for Feeble-Minded Girls and Boys, the first clinical laboratory to study intellectual disabilities.
Published in 1912, The Kallikak Family: A Study in the Heredity of Feeble-Mindedness was Goddard’s best-known book. He studied a “family” in upstate New York—actually a grouping of people possibly but not definitely related—and concluded that they were all descended from a single Continental Army soldier. According to Goddard, Martin Kallikak first married a Quaker woman and all of the offspring that came from the marriage were intelligent and resourceful and demonstrated no indications of mental defectiveness. Goddard discovered that Kallikak’s liason with a "feeble-minded" girl, however, resulted in "a race of defective degenerates."
Though welcomed by most American eugenicists, The Kallikak Family attracted widespread criticism for its careless and imprecise research methodology and conclusions. Within a decade Goddard himself considered the book unsound and its conclusions to be neither accurate nor defensible.
