The library is originated in Switzerland, when the Swiss Esperanto Society opened a library in 1908. In 1912, the library came to the possession of Hector Hodler, the founder of Universal Esperanto Association (UEA). After his death, it was under UEA in Switzerland. After World War II, in 1947, the library was renamed the Hector Hodler Library in his honour. Along with the translocation of the UEA headquarter to Rotterdam, the library was settled there in 1960.
