Thorald Jerichau

Thorald Harald Adolph Carol Lorentz Jerichau (1 November 1848, Copenhagen – 25 December 1909, Christiania) was a Danish organist and composer.

An original three-line sheet music system that he invented was never used, although he put much time and effort into promoting it.

By chance, one copy survived: a series of marches for piano that he had given to a young boy on the island of Bogø.

For many years, he was employed as an organist in Horsens then, in 1890, went to the United States, where he began a concert tour and, allegedly, served as head of a music conservatory.

Upon returning from America, he effectively took charge of his young nephew (his brother Holger's son), Jens Adolf [da].
