Valdemar Langlet

Swedish Righteous Among the Nations, publisher and Esperantist (1872-1960)

The protective documents issued by Valdemar Langlet in 1944 provided individuals with a false claim to Swedish nationality, effectively insulating thousands from deportation to German concentration camps. Working from Budapest alongside his wife Nina Borovko-Langlet, he operated under the auspices of the Swedish Red Cross to establish a network of safehouses, orphanages, and food distribution centers for the persecuted.

Early Career and Linguistic Interests

Born in 1872 at Lerbo socken, Langlet was the son of architect Emil Victor Langlet and author Clara Mathilda Ulrika Clementine Söderén. After completing his studies in Germany, Austria, and Switzerland, he worked as an engineer before shifting into journalism and publishing. He served as an editor for various Swedish newspapers, including Svensk Handelstidning and Svenska Dagbladet, and authored multiple accounts of his travels through Russia and Hungary. Langlet gained prominence within the Esperanto community as a founding member of the Uppsala club in 1891 and later served as president of the Swedish Esperanto Federation until 1909.

Diplomatic Tenure in Budapest

In 1932, Langlet relocated to Budapest to accept a position as a lecturer of the Swedish language at the University of Budapest. Simultaneously, he maintained a role as an officer at the Swedish Embassy. During his tenure, he cultivated extensive relationships with local families, providing him with a network that would prove critical when the geopolitical situation in Hungary deteriorated significantly in 1944. As the fascist regime and the German SS intensified their efforts against Jewish populations, Langlet witnessed the sudden disappearance of his associates.

Humanitarian Operations and Legacy

Initiating his rescue operations without explicit authorization from Stockholm, Langlet leveraged his embassy status to issue documents verifying that holders were awaiting Swedish nationality. This mechanism served as a template for Raoul Wallenberg’s later efforts in the region. Beyond documentation, the Langlets secured numerous properties to shelter the vulnerable, offering food and medical aid. Following the conclusion of the war, his efforts were formally recognized in 1965 when he and his wife were named Righteous Among the Nations by Yad Vashem. Langlet died in 1960 in Sankt Matteus.
