Verlag Karl Baedeker, founded by Karl Baedeker on July 1, 1827, is a German publisher and pioneer in the business of worldwide travel guides. The guides, often referred to simply as "Baedekers" (a term sometimes used to refer to similar works from other publishers, or travel guides in general), contain, among other things, maps and introductions; information about routes and travel facilities; and descriptions of noteworthy buildings, sights, attractions and museums, written by specialists.
1827−1859: Karl Baedeker (see article) had three sons, Ernst, Karl and Fritz and after his death each, in turn, dictated by events, took over the running of the firm.
1859−1861: Following the death of Karl Baedeker, his eldest son Ernst Baedeker (1833−1861) became the head of the firm. After his training as a bookseller in Braunschweig, Leipzig and Stuttgart, he had spent some time at the English publishing house "Williams & Norgate" in London. On New Year's Day, 1859, he had joined his father's publishing firm as a partner and just ten months later he was running it on his own.
His tenure at the helm of the firm saw the publication of three new travel guides in 1861 viz the first Baedeker travel guide in English, the handbook on "The Rhine" (from Switzerland to Holland), a guide in German on Italy (Ober-Italien), the first of a series on Italy, which his father had planned and one in French, also on Italy (Italie septentrionale).
Ernst Baedeker died unexpectedly on 23 July 1861 of sunstroke in Egypt and his younger brother, Karl, assumed charge of the publishing house.
1861−1877: Karl Baedeker II (1837−1911) continued the work started by his brother Ernst. In addition to the ongoing revision of existing guides, he published 14 new guides: four in German, seven in English and three in French. viz.
Karl Baedeker II worked with his younger brother Fritz, who joined the firm in 1869 as a partner and became the general manager. In 1877 (according to the source cited here) Karl, afflicted with an incurable mental condition, moved to a sanatorium near Esslingen am Neckar where he remained for the rest of his life.
