"Carl Gustaf Tessin (5 September 1695 – 7 January 1770) was a Swedish Count and politician and son of architect Nicodemus Tessin the Younger and Hedvig Eleonora Stenbock. He was one of the most brilliant personages of his day, and the most prominent representative of French culture in Sweden. He was also a fine orator.
Tessin´s art collection became the original core of the collection of Sweden´s Nationalmuseum." - (en.wikipedia.org 27.10.2020)
