's life
Marquardt, born in Berlin on December 2, 1818, had a successful career as an architect, becoming professor and later inspector general of building for the Grand Duchy of Baden. His most notable achievement was the Karlsruhe Palace in the city of Karlsruhe, Germany. He was a leader in the development of the neoclassical style and was part of the movement to create clearer and more rational urban spaces. At the same time, Marquardt pushed back against the traditional academic architecture, advocating instead the use of stone and brick. His ideas and designs later became part of the German Historicism movement. He was also a passionate collector of art and antiquities, and worked with many painters, gravemakers and sculptors to create sculptures and decorative elements in his projects.
