The roots of the company go back to 1749 when
Frederick the Great granted the
Königliche Realschule in Berlin the
royal privilege to open a bookstore and "to publish good and useful books". In 1800, the store was taken over by Georg Reimer (1776–1842), operating as the ''Reimer'sche Buchhandlung'' from 1817, while the school's press eventually became the
Georg Reimer Verlag. From 1816, Reimer used a representative palace at Wilhelmstraße 73 in Berlin for his family and the publishing house, whereby the wings contained his print shop and press. The building later served as the
Palace of the Reich President. Born in
Ruhrort in 1862, Walter de Gruyter took a position with Reimer Verlag in 1894. By 1897, at the age of 35, he had become sole proprietor of the hundred-year-old company then known for publishing the works of German romantics such as
Johann Gottlieb Fichte,
Friedrich Schleiermacher, and
Heinrich von Kleist. De Gruyter later acquired four other publishing houses – Göschen, Guttentag, Trübner, and Veit – and, in 1919, merged them into one:
Vereinigung wissenschaftlicher Verleger Walter de Gruyter & Co., located in Genthiner Straße, where it is still headquartered today. The four publishers specialized in philosophy, theology,
German literature, medicine, mathematics, engineering, law,
political science, and
natural science, and it is for many classics in these fields that de Gruyter is still known today. By the time he died in 1924, Walter de Gruyter had created one of the largest modern publishing houses in Europe. De Gruyter's son-in-law, Herbert Cram (1893–1967) succeeded him in the management of the company and it continues to be family-owned. During
World War II, the roof and top floor of the de Gruyter building were destroyed and the basement warehouse flooded, but the building itself survived. On 14 May 1945, the publisher again registered for trading and was the first publisher in the
British zone to receive a license. The company became Walter de Gruyter GmbH in 2012. In October 2023, it was announced that De Gruyter would acquire the Dutch publisher
Brill for €51.1 million, forming the new company De Gruyter Brill, by the second quarter of 2024. == Imprints and partnerships ==
