19th-century German architects

Friedrich Weinbrenner (24 November 1766 – 1 March 1826) was a German architect and city planner admired for his mastery of classical style.

Adolf Ludwig Cluss (July 14, 1825 – July 24, 1905) also known as Adolph Cluss was a German-born American immigrant who became one of the most important, influential and prolific architects in Washington, D.C., in the late 19th century, responsible for the design of numerous schools and other notable public buildings in the capital. Today, several of his buildings are still standing. He was also a City Engineer and a Building Inspector for the Board of Public Works.
Red brick was Cluss' favorite building material; that, and his early communist sympathies, led some to dub him the "Red Architect", though he was a man who in later life became a confirmed Republican.

Heinrich Tessenow (7 April 1876 – 1 November 1950) was a German architect, professor, and urban planner active in the Weimar era.

Martin Wagner (1885–1957) was a German architect, city planner, and author, best known as the driving force behind the construction of modernist housing projects in interwar Berlin.

Franz Heinrich Schwechten (12 August 1841 – 11 August 1924) was one of the most famous German architects of the Wilhelmine era, and contributed to the development of historicist architecture.

Hans Poelzig (30 April 1869 – 14 June 1936) was a German architect, painter and set designer.
