International Federation of Architects, Engineers, Chemists and Technicians

The International Federation of Architects, Engineers, Chemists and Technicians is presented in the book through archival references and accusations that placed the organization within investigations of communist activity and alleged espionage connected to atomic research. The surviving references establish that it attracted official scrutiny; they do not, by themselves, establish the truth of the accusations against it.

The Federation in investigative records

A 1944 FBI report described Thomas Addis as active in 27 Communist front organizations in the San Francisco Bay Area during the preceding ten years. The source cited for this account also refers to a federation file, alongside a Comintern archival reference. These citations place the federation within the documentary trail concerning Addis and left-wing organizations, but they do not specify his relationship to the federation or establish that it engaged in espionage.

Allegations concerning atomic research

The federation received a more specific accusation in a lengthy report included in a 1947 report by the California Joint Fact-Finding Committee on Un-American Activities. R. E. Combs charged that it had been used as a front for communist espionage connected with atomic research at the University of California Radiation Laboratory. This is reported as an accusation made in a political investigation, not as a finding independently substantiated by the account.

What the record establishes

The book’s evidence connects the federation to two overlapping settings: scrutiny of communist-front organizations in the San Francisco Bay Area and allegations of espionage tied to research at the University of California Radiation Laboratory. It supplies no account of the federation’s internal structure, membership, or activities beyond these references. Its significance here therefore lies in how its name entered the security and anti-communist investigations surrounding atomic science, while the distinction between a documented allegation and proven conduct remains essential.
