Frank Le Maistre (1910–2002), compiler of the Jèrriais–French dictionary, maintained a literary output starting in the 1930s with newspaper articles under the pseudonym "Marie la Pie", poems, magazine articles, and research into toponymy and etymology. He himself considered his masterpiece to be his translation of the Rubaiyat of Omar Khayyam into Jèrriais that he made during the German Occupation (1940–1945).
