Eugenics Records Office

The Eugenics Records Office, or the ERO, was located at Cold Spring Harbor, Long Island. It sought to accumulate and study the records of physical and mental characteristics of human families and to educate the public as to classes of fit and unfit marriages. According to the American Breeders Association's charter, its work was done by means of correspondence, the acquisition of family records on special blanks, and the inquiries of field workers.

Bell worked on ERO's scientific board which worked on issues such as "the consequences of marriage between different races", "the study of America's most effective bloodlines", and "restricting the strains that require care".
