Jens Bjørneboe (1920-1976) was a Norwegian poet, playwright, essayist, and novelist who was arguably one of the most important writers of the mid-twentieth century. He was also a visual artist, a Waldorf School teacher, and a renowned social critic. Although little known in the English-speaking world, his work has been translated into a number of European and world languages and remains highly regarded in Scandinavia. His last major work was The Sharks (Haiene, 1974) and his most critically acclaimed were the three volumes making up the The History of Bestiality trilogy; all have been translated into English by Esther Greenleaf Mürer.

Esther Greenleaf Mürer is a poet and translator who resides in Philadelphia. She has previously translated Bjørneboe's novels The Sharks (Norvik, 1992), Moment of Freedom (Norvik/Dufour, 1999), Powerhouse (Norvik/Dufour, 2000), and The Silence (Norvik/Dufour, 2000) as well as a number of his essays and poems. She was responsible for the "Jens Bjørneboe in English" website, which was the premiere source of information about Jens Bjørneboe written in English and included translations of his poetry, essays, and excerpts of other works.
