WHY DID D'HAUBERAT COME TO GERMANY?
Guillaume d'Hauberat received his education at the Paris school of the important French royal architect, Robert de Cotte. In 1716, de Cotte brought him to Bonn. D'Hauberat was to support Cotte with the intended construction for the Prince-Elector of Cologne, Joseph Clemens von Bayern. In the process, the architect ended up in the role of an intermediary between de Cotte's office in Paris and the construction in Bonn. Ten years later, d'Hauberat followed the call of Prince-Elector Carl Philipp von der Pfalz to the court at Mannheim.
