[1] Carl Ludvig Thilson Locher was born in Flensburg in the Duchy of Schleswig which was then part of Denmark.
After the father died, he continued his business for a short while and went on several voyages with ships of the Royal Danish Navy.
Struck by the grandeur of the Atlantic Ocean, a voyage to the Danish West Indies made a particular impression on him.
[2] Even before he began his studies at the Royal Danish Academy of Art in 1872, he was encouraged by Holger Drachmann to spend a couple of months in Skagen, the artists colony in the far north of Jutland.
As an etcher Locher was regarded among the best and most productive of the Danish artists; From 1885 he made a number of smaller and larger prints, with a lot of picturesque energy.
