Louis Frederick Roslyn, born Louis Frederick Roselieb, also known as Louis Fritz Roselieb (13 July 1878 – 1940), was a British sculptor noted for his World War I war memorials and other sculptures. Before beginning his career, he studied at Westminster City & Guilds College and the Royal Academy. He enlisted in the Royal Flying Corps in 1915, but for medical or other reasons was put on the reserve until 1917 when he was called to the School of Military Aeronautics and subsequently made Lieutenant. It seems to be during his military service that he finally changed his name to Roslyn.
