Carl Haeberlin (15 December 1870 – 12 November 1954), sometimes also spelled Häberlin, was a German physician and natural historian.
He was influential for the development of climatotherapy and thalassotherapy in Germany and founded the Dr. Carl-Häberlin-Friesenmuseum in Wyk auf Föhr.
The family moved back to Germany in 1873 and settled in Swabia where Carl Haeberlin spent his youth.
Together with Karl Gmelin he established a centre for bioclimatic research in Wyk auf Föhr which opened in 1926.
[1][2] Already in the early 1900s, Gmelin's and Haeberlin's activities attracted increasing numbers of tourists to the seaside spa of Wyk which had previously been less frequented.
