Ludwig Josef Johann Wittgenstein was born in Vienna in 1889 to a wealthy industrialist family and pursued an education in mechanical engineering before going on to study, and later to teach at the University of Cambridge, where he lived until his death in 1951. He is regarded by many as the greatest philosopher of the twentieth century, and his two major works, the Tractatus Logico-Philosophicus (1921) and Philosophical Investigations (published posthumously in 1953), are two of the most influential works within the history of the analytic tradition. Jan Zwicky (Introducer) is a Canadian philosopher, poet, and musician. Her poetry collections include Songs for Relinquishing the Earth, The Long Walk, and Wittgenstein Elegies. Her philosophical works include Lyric Philosophy, Wisdom & Metaphor, and The Experience of Meaning. Alexander Booth (Translator) is a poet and literary translator living in Berlin. He received a PEN/Heim Translation Fund Grant for his translations of the German poet Lutz Seiler in 2016. His work has been published in several international journals.
