Miguel de Unamuno y Jugo (29 September 1864 – 31 December 1936) was a Spanish essayist, novelist, poet, playwright, philosopher, professor of Greek and Classics, and later rector at the University of Salamanca.
Tragic Sense of Life, published in 1912, was his most important philosophical work and is now generally considered one of the great existential texts of the 20th century—as provocative a work in its own right as anything written during the post-war period by Sartre, Camus, or Heidegger.
