Carl Johan Cronstedt 1709–1779

Carl Johan Cronstedt was a man of versatile talents. As well as architecture, he also came up with technological advances. Cronstedt is probably best known for his involvement in one of the most important Swedish inventions of the 18th century: the tiled stove. Working together with Fabian Wrede, he designed a structure with a pipe system where the flue gases were led around in a loop to give off heat more efficiently.

Cronstedt began his career in castle construction and accompanied Carl Hårleman on a trip to Paris in 1731, where – like Hårleman – he was inspired by the French Rococo. Cronstedt was in charge of all the craftsmen employed in the continued construction of the Royal Palace. He was appointed as the new Superintendent after Hårleman's death, and the current Bernadotte Library at the Royal Palace is thought to be one of his creations.
