Elias David Häusser

Häusser was born in Erfurt, Prussia (Preußen). His parents were David Häusser (1645-1709) and Johanna Maria Evander (1666-1741). He spent some time at the court of the Duke of Saxe-Gotha and was educated as a military building master in Saxony-Poland. In 1711 he came into Danish military service. In the capacity of an officer in the engineering troops, he was in charge of several projects in Copenhagen, including the Central Guard on Kongens Nytorv and the Commander's House and prison at Kastellet. In the early 1730s, King Christian VI commissioned him as master builder of a new grand castle, Christiansborg Palace, on the site of the old Copenhagen Castle, which had been torn down in 1731. He left the project in 1741, a few years before it was completed, to assume a position as Commander and later Major General in Nyborg on the Danish island of Funen. He died there in 1745.
