However, in 1823 Jean Georg Haffner, a former medic of the French army, financed a new bath complex that gained significant popularity. In the following years, Haffner erected more facilities. By 1824, a sanatorium was opened to the public, as well as a 63-metre pier, cloakrooms, and a park. Haffner died in 1830, but his enterprise was continued by his stepson, Ernst Adolf Böttcher. The latter continued to develop the area and in 1842 opened a new theatre and sanatorium. By then the number of tourists coming to Zoppot every year had risen to almost 1,200.
