Walter de Gruyter GmbH ( or ; brand name:
De Gruyter) is a
scholarly publishing house specializing in academic literature. The company has its roots in the bookstore of the
Königliche Realschule in
Berlin, which had been granted the
royal privilege to print books by King
Frederick II of Prussia in 1749. In 1801 the store was taken over by Georg Reimer. In 1919, Walter de Gruyter (1862–1923) merged it with 4 other publishing houses into the company that became
Verlag Walter de Gruyter & Co in 1923, and
Walter de Gruyter GmbH in 2012.
