Tomas Tranströmer, winner of the 2011 Nobel Prize in Literature, was one of the most celebrated and influential poetic figures of his generation. He was born in Stockholm in 1931 and educated at the Södra Latin School and the University of Stockholm, where he received a degree in psychology. He began his psychology career in the early 1960s at Roxtuna, a juvenile corrections institute in Sweden, and worked for several decades in the field. Since the publication of 17 Dikter (17 Poems) in 1954, Tranströmer wrote eleven full-length collections of poetry, most recently Den stora gåtan (The Vast Enigma) in 2004. He was one of the world's most translated poets (with books appearing in numerous editions in over fifty languages). In addition to his renown as a poet, Tranströmer was also a highly regarded concert pianist and entomologist. He died in Stockholm in 2015.
