José Castellanos Contreras

Salvadoran diplomat and Righteous Among the Nations (1893-1977)

Thousands of Central European Jews secured safe passage during World War II by carrying fake citizenship papers issued by José Castellanos Contreras. Working as a diplomat in Geneva, the Salvadoran colonel collaborated with businessman György Mandl to provide documentation that shielded individuals of Bulgarian, Czechoslovak, Hungarian, Polish, and Romanian descent from Nazi persecution and deportation to concentration camps.

Military Career and Diplomatic Service

Born in 1893 in San Vicente to General Adelino Castellanos and Isabel Contreras de Castellanos, he entered the Military Polytechnic School in 1911. His military career spanned over 25 years, reaching the rank of Second Chief of the General Staff of the Army of the Republic. In 1937, he transitioned into diplomatic service, holding consul general positions in Liverpool and Hamburg before arriving in Geneva in 1942.

Operations in Neutral Switzerland

While serving in neutral Switzerland, Castellanos met the Jewish businessman György Mandl. Recognizing the dire threat posed to Mandl and his family, the consul appointed him as First Secretary and issued them Salvadoran nationality papers under the name Mantello. With official consent, this partnership expanded into a covert operation to distribute 13,000 certificates of citizenship. These documents allowed bearers to seek protection from the International Red Cross and the Swiss Consul in Budapest.

Post-War Secrecy and Recognition

After the conflict, Castellanos maintained a quiet life, rarely discussing his wartime activities. His family remained largely unaware of his actions until the 1970s, when writer Leon Uris interviewed him. International recognition followed decades later, including a 1995 letter of tribute from President Bill Clinton. In 2010, the Holocaust Martyrs' and Heroes' Remembrance Authority at Yad Vashem awarded him the title of Righteous Among the Nations.
