Forschung und Freizeit: Karl von Frischs Aufenthalt in Neapel 1911**

In March 1911, Karl von Frisch visited the Zoological Station in Naples for the first time. During his stay, Frisch, who had just received his doctorate, was studying the color adaptation of marine fish. At the same time, as diary notes show, he also completed an extensive tourist program. Frisch was not alone in this; many scientists combined their time in Naples with excursions and other pleasures. Usually these activities are labelled—in Frisch's words—as „diversion“ and „relaxation“ from the activities in the laboratory. Expanding this point, I will examine the various relationships between labour, recreation, research, and tourism based on Frisch's notes during his stay in Naples. Finally, I will take a look at the financial side of Frisch's stay in Naples.
