Executive Order 10422

American Prometheus

Executive Order 10422 was a security-screening requirement for American employees of the United Nations. The account records its practical effect in early 1954, when Haakon Chevalier was denied employment by UNESCO because he refused to comply.

Scope and Requirement

Issued on January 9, 1953, the order required American employees of the United Nations to pass a security investigation. The evidence describes a condition of employment for this category of staff, not a general screening rule for all workers or a finding about any particular person’s conduct.

Application to Haakon Chevalier

By early 1954, Chevalier had been denied any type of employment by UNESCO because of his refusal to comply with the order. The account also notes that he never reapplied for a United States passport. It does not specify the investigation’s procedures or establish that the passport decision and the employment denial were the same process.

Documented Significance

The episode shows the order’s reach into employment at an international organization: refusal to undergo the required investigation carried a professional consequence for Chevalier. The evidence establishes that consequence but does not describe the order’s broader administration or the outcome of any review of his case.
