The Secret Intelligence Service, Passport Control and Jewish Refugees from the Third Reich, 1938–1939.

This article examines the role of British Secret Intelligence Service (SIS) officers, operating under cover as Passport Control Officers (PCOs), in assisting Jewish refugees fleeing Nazi persecution during the 1930s. It highlights that while individuals like Captain Frank Foley in Berlin and Captain Thomas Kendrick in Vienna have been celebrated for their efforts, the broader collective work of over fifty passport control staff was crucial in processing visas amid a growing refugee crisis. The article details how SIS's espionage activities were largely sidelined as visa issuance became a humanitarian priority, constrained by strict immigration policies and bureaucratic challenges, and how the reintroduction of visa requirements in 1938 dramatically increased their workload. It also addresses the limitations of PCOs' authority, the complex interplay between intelligence and humanitarian duties, and cautions against overstating individual contributions without acknowledging the collective effort and the difficult political context. Ultimately, the article underscores the need for careful, non-partisan research to understand the true impact of SIS/PCO personnel in aiding refugees before World War II.
