What German doctor was also friends with Schack Carl Rantzau?
Johann Friedrich Struensee Johann Friedrich Struensee (5 August 1737 – 28 April 1772) was a German doctor. He became royal physician to the mentally-ill King Christian VII of Denmark and a minister in the Danish government. He rose in power to a position of ""de facto"" regent of the country, where he tried to carry out widespread reforms. His affair with Queen Caroline Matilda ("Caroline Mathilde") caused a scandal, especially after the birth of a daughter, Princess Louise Augusta, and was the catalyst for the intrigues and power play that caused his downfall and dramatic death.
Carl Gustav Carus Carl Gustav Carus (3 January 1789 – 28 July 1869) was a German physiologist and painter, born in Leipzig, who played various roles during the Romantic era. A friend of Johann Wolfgang von Goethe, he was a many-sided man: a doctor, a naturalist, a scientist, a psychologist, and a landscape painter who studied under Caspar David Friedrich.
