Lars-Terje Lysemose is a Danish journalist, editor and educator. A member of The Tolkien Society in the early 1990s, he founded what is now known as Imladris, Danmarks Tolkienforening (then, Danmarks Tolkienforening) together with Inge Søbæk in 1993.
He also became the editor for Athelas, the journal of the Society. As the Appendices were not included in the Danish edition of The Lord of the Rings, Lysemose published a translation running through several issues of Athelas.
In 1997, Lysemose moved to the United States.
