(b Hillerød, 8 Dec 1816; d Hillerød, 25 May 1880). Danish painter. He joined the Akademi for de Skønne Kunster in Copenhagen at the age of 16. At the same time he frequented Johan Ludwig Gebhard Lund’s studio, which was a meeting-place for such future leading National Romantic landscape painters as Johan Thomas Lundbye and Peter Christian Thamsen Skovgaard. He intended originally to become a history painter, but towards the late 1840s he adopted landscape painting. View of the Common at Frederiksborg (1848; Copenhagen, Stat. Mus. Kst) is one of his early landscapes, an evocation of a passing moment, painted in light colours. Rump was one of the first Danish painters to finish his pictures en plein air, despite the fact that they were often large-scale works, and this enabled him to retain that freshness which is characteristic of the sketch. During the 1850s his paintings changed: the compositions became calmer and the colours warmer. His great interest in the play of sunlight on foliage is apparent in the painting of beech trees in the Brook in Sæbygaard Wood in Vendsyssel (1854; Copenhagen, Stat. Mus. Kst).
