The story
Founded by Gustav Langenscheidt in 1856, in Berlin.1
The Langenscheidt Publishing Group was founded on 1 October 1856 by Gustav Langenscheidt, in response to other publishers' refusal to publish his self-study materials for learning French, which he subsequently published under the title „ Unterrichtsbriefe zur Erlernung der französischen Sprache“ ("Teaching letters for learning the French language"). These learning materials became very popular and were widely read so much so that even today, Langenscheidt can be considered the "Father of distance education". From 1867, Langenscheidt Publishing Group had its own printing press.
From 1869 Langenscheidt worked with Karl Sachs and Césaire Villatte on the Encyklopädisches französisch-deutsches und deutsch-französisches Wörterbuch ("Encyclopedic French-German and German-French dictionary") and published it in 1880. In 1874, Langenscheidt was awarded the title of professor.
In 1891, in close collaboration with Eduard Muret and Daniel Sanders, he started working on the English equivalent, the Encyklopädisches englisch-deutsches und deutsch-englisches Wörterbuch ("Encyclopedic English-German and German-English dictionary"). Langenscheidt did not live to see its publication; his son Carl, his successor, published it in 1901.
From before 1870 to 1970, Langenscheidt bilingual dictionaries were popular among language students and various schools.
In 2019, Langenscheidt was acquired by Klett, owner of the competing dictionary Pons.
