Haeberlin was born in
Ranchi, India, as the son of a Christian missionary. The family moved back to Germany in 1873 and settled in
Swabia where Carl Haeberlin spent his youth. He studied medicine, passed his exams in 1895 in
Tübingen and received a
doctorate. In 1902, he moved to
Wyk auf Föhr on
Föhr island in the North Sea where he began to practice. Apart from activities as a
balneologist he also worked intensively on climatotherapy and thalassotherapy. His studies and reports formed the basis for the development of these disciplines in Germany. Together with Karl Gmelin he established a centre for bioclimatic research in Wyk auf Föhr which opened in 1926. 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. In 1902 and 1919 he published two chronicles of the town of Wyk and Wyk as a seaside resort respectively. A museum of natural history and local history in Wyk that he had founded in 1908 was named
Dr. Carl-Haeberlin-Museum in his honour in 1927. The museum displays artifacts from the Viking Age, the
Age of Sail, and paintings with local motives. ==Awards and honours==
