Lothar Grund was born in Schwerin, Germany, on October 22, 1923. In 1950, he moved to Iceland, where he met actress Anna Þorbjörg Halldórsdóttir. They married on July 25, 1952, and had three sons: Pétur Adolf Garðar, Atla Halldór, and Alfreð. The family moved to Germany in the late 1950s and settled in Hamburg. Lothar died on November 15, 1995. From 1951 to 1958, Lothar worked on more than fifty plays in Iceland. They were of all sizes and types, for various theater companies, both amateur and professional. His ambition, experience, and artistry had an immeasurable influence on Icelandic set and costume design. Lothar's private archive (LMÍ 2022/6) spanning his career in Icelandic performing arts is preserved in the Icelandic Theatre Museum. The collection contains more than three hundred stage and costume drawings, as well as several drawings and paper figures for Richard Wagner's Der Rheingold, a project that was not staged in Iceland. On the occasion of Lothar's centenary, the National Library of Iceland – University Library and the Theatre Museum are exhibiting a selection of his drawings and placing them in context with Icelandic performing arts in the 1950s. Three exhibitions that have been staged at the National Theatre will receive special attention, as they feature his most unique works, despite the fact that the exhibitions are very different and that they have received very different reactions, both from audiences and theatre critics.
