Berlitz Language Schools, now known as Berlitz International, Inc, derive from an institution founded by Maximilian Berlitz in 1878, in Providence, Rhode Island. It has now expanded into an international organization with some 600 schools worldwide. The school teaches languages with its own “Berlitz Method of language instruction”. When first developed, the foundation of the method was based on language being taught in the target language only. This has now evolved to incorporate other aspects of language learning and language acquision theories.
