Kjerulf, Halfdan (1815-1868), Norwegian musical composer, the son of a high government official, was born at Christiania on the 15th of September 1815. His early education was at Christiania University, for a legal career, and not till he was nearly 26—on the death of his father—was he able to devote himself entirely to music. As a fact, he actually started on his career as a music teacher and composer of songs before ever having seriously studied music at all, and not for ten years did he attract any particular notice. Then, however, his Government paid for a year’s instruction for him at Leipzig. For many years after his return to Norway Kjerulf tried in vain to establish serial classical concerts, while he himself was working with Björnson and other writers at the composition of lyrical songs. His fame rests almost entirely on his beautiful and manly national part-songs and solos; but his pianoforte music is equally charming and simple. Kjerulf died at Grefsen, on the 11th of August 1868.
