With an encompassing retrospective on Christoffer Wilhelm Eckersberg (1783–1853), presented for the first time outside of Denmark in Europe, the Hamburger Kunsthalle is paying tribute to the most prominent Danish painter of the first half of the 19th century. On 9 May 1814 Eckersberg had bought a portable paintbox and a folding chair in order to paint in the Eternal City and in the Roman Campagna. He thus established the Danish tradition of outdoor painting in Rome. Innovations regarding the direct study of nature alongside geometry and perspective made up the principal components of his teachings at the Copenhagen Academy, where he was engaged as a professor for almost 40 years. Through his progressive approach of combining tradition with innovation, and classism with realism, Eckersberg not only became the most distinguished Danish painter of the first half of the 19th century, but also one of the defining figures for the European development of art during this period.
