Walter de Gruyter GmbH, known as De Gruyter (German: [də ˈɡʁɔʏ̯tɐ]), is a German scholarly publishing house specializing in academic literature.
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 the representative Sacken'sche Palace on Berlin's Wilhelmstraße for his family and the publishing house, whereby the wings contained his print shop and press. The building became a meeting point for Berlin salon life and later served as the official residence of the president of Germany.
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 addition to its headquarters in Berlin, De Gruyter maintains offices around the globe, namely in Munich, Vienna, Basel, Warsaw, Boston, and Beijing.
Several former publishing houses have become imprints of De Gruyter:
De Gruyter is one of thirteen publishers to participate in the Knowledge Unlatched pilot, a global library consortium approach to funding open access books.
