Interlingua is an Italic international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It ranks among the most widely used IALs and is the most widely used naturalistic IAL – in other words, those IALs whose vocabulary, grammar and other characteristics are derived from natural languages, rather than being centrally planned. Interlingua literature maintains that (written) Interlingua is comprehensible to the hundreds of millions of people who speak Romance languages, though it is actively spoken by only a few hundred.

Richard "Ric" Berger (1894–1984) was a Swiss professor of design, decoration, and art history. He is best known for his numerous newspaper articles about historical monuments, mainly in the French-speaking part of Switzerland, including his own drawings of the buildings. Through these articles, he contributed to an increased interest in historical monuments and settings among many hitherto uninformed people, and probably also contributed indirectly to a wider interest in preserving and saving historical monuments from destruction.
