The Eugenics Record Office

The movement’s filing cabinet — where ranking the stock became a data operation.12

Documented core

Charles Davenport founded the ERO at Cold Spring Harbor in 1910 with a grant from Mary Harriman, widow of the railroad magnate E. H. Harriman, and appointed Harry Laughlin its superintendent. In 1917 the Carnegie Institution assumed primary funding; the Rockefeller Foundation also contributed. Its work was the mass collection of family pedigrees and “trait” records — the empirical apparatus by which “feeble-mindedness” and defect were certified as hereditary and actionable. It closed in 1939, its methods by then scientifically discredited.

Asserted intent — firewalled

That the great fortunes behind the office — Harriman, Carnegie, Rockefeller — prove a coordinated century-long design is unsupported synthesis. What is documented is the philanthropic funding of a research office; the reading that turns co-funding into directed conspiracy is exactly the density-temptation this rail must resist. The office is a co-symptom of the root, one operator among many, never its hidden engine.

Role in the thesis

Enactment. The ERO is where the root acquires an archive: a bureaucratic engine for grading the human stock, funded and staffed in the open, its records the paper on which sterilization and exclusion were later argued.
