Franz Heinrich Schwechten
Franz Heinrich Schwechten was one of the most famous German architects of his time, and contributed to the development of historicist architecture.
Schwechten was born in Cologne, the son of a district court judge. He attended Gymnasium, taking his Abitur in 1860, and went on to work as an apprentice of master builder Julius Carl Raschdorff, who would later design the Berlin Cathedral. In 1861, Schwechten enrolled in the Bauakademie in Berlin, where he studied under Karl Btticher and Friedrich Adler. During a practical training period following the completion of his studies in December 1863, Schwechten worked first for several months with Friedrich August Stler, until May 1864, and then with Martin Gropius, until June 1865.
