Arild Stubhaug is an acclaimed poet and biographer. Born in 1948 in Naustdal, Norway, he holds university degrees in mathematics, literature, and the history of religion. He has also been awarded an honorary doctorate by the University of Oslo. He made his literary debut in 1970 with a poetry book, and he has since published numerous collections of poetry and other important literary works. His biography Niels Henrik Abel and His Times: Called Too Soon from Flames Afar (published in English by Springer-Verlag, 2000) won the prestigious Brage Prize in Norway in 1996. This was followed by two other major works: The Mathematician Sophus Lie: It Was the Audacity of My Thinking (also published in English by Springer-Verlag, 2002), and a biography of the Norwegian writer Conrad Nicolai Schwach.

From the reviews: "This book is a biography about a mathematician; the focus is on the man and his life ... . Mittag-Leffler's life is covered in at times minute detail. ... it is an important biography of a man that played a significant role in the development of the modern mathematical community." (Charles Ashbacher, The Mathematical Association of America, January, 2011) "This is the English translation of a thorough biography of the Swedish mathematician Gosta Mittag-Leffler first published in Swedish in 2007. ... The book was years in the writing and is exhaustively researched ... . this book is richly informative ... . It is handsomely printed, well illustrated, and generally well translated." (Jeremy Gray, Mathematical Reviews, Issue 2011 k) "There are many photographs in Stubhaug's book, in some of which Mittag-Leffler bears a striking resemblance to Mark Twain. ... The translation from Norwegian is mostly very smooth ... . As a biography of a complex, controversial, highly gifted man who interacted with many of the great figures of his time, this is ... a very good read." (Peter Giblin, The Mathematical Gazette, Vol. 96 (536), July, 2012)
