Born in Bergen Norway and trained at the Copenhagen Academy, Johan Christian Clausen Dahl (1788-1857) nonetheless spent most of his working career in Germany.
He is thus claimed by all three schools for their own, although it was his influence on the latter that was more important, as from 1824 until his death he held the senior professorship of art at the Dresden Academy.
His memories of his homeland, however, provided him with themes that he reused throughout his career, but it was his attention to nature and use of the plein-air sketch that earned him the Dresden appointment in preference to Friedrich.
