Ludwig Boslet was a German late romantic composer and organist. As many of his contemporaries largely forgotten through history because of the now famous musical giants of that time. He felt very connected to his home country, so he declined offers from Alexandre Guilmant from Paris and other offers from the USA and England. In 1911 he became the organist of the Trierer Dom.
