Emma Wolverton, also known as Deborah Kallikak, lived her entire life in an institution in New Jersey after psychologist Henry Goddard classified her as feeble-minded. He also wrote a book about Wolverton and her family that psychiatrists previously used to show that intellectual disability is hereditary. At the time, researchers in the psychology field, including Goddard, were working to understand differences in people’s intellectual abilities. They used the term feeble-minded to refer to those they described as having lower intellectual functioning. While Wolverton spent nearly her entire life living and working in institutions for the feeble-minded, more recent investigations of her life show she was not what is now considered intellectually disabled. Wolverton’s involvement in Goddard’s research as Deborah Kallikak influenced twentieth century ideas around the heritability and treatment of those with disabilities.
