Sorley MacLean
Sorley MacLean (; 26 October 1911 – 24 November 1996) was a Scottish Gaelic poet, described by the Scottish Poetry Library as "one of the major Scottish poets of the modern era" because of his "mastery of his chosen medium and his engagement with the European poetic tradition and European politics". Nobel Prize Laureate Seamus Heaney credited MacLean with saving Scottish Gaelic poetry.
