Ludvik Mrzel (pen name Frigid)[1] (28 July 1904 – 29 September 1971) was a Slovene writer, poet, dissident and journalist.

He also published book and theater reviews, and reports about cultural events among Slovene emigrants to the United States.

As a result, many writers and journalists including Mrzel who were critical of Tito and the communist regime were arrested and jailed.

He was charged with "mysticism" and "literary fetishism," and was eventually sentenced to 12 years in prison in 1949 during the Dachau trials.

[5] Mrzel's translations include Russian and Ukrainian fairy tales and writings by Knut Hamsun, Alexis Steiner, Theodor Plievier, Franz Werfel, Antonius Roothaert, Vasily Chuikov, Andrey Yeryomenko, Günther Anders, Jean Rousselot, John Knittel, Sergei Aleksandrovich Tokarev, and Karl May.
