Fernando António Nogueira Pessoa (Lisbon, June 13th, 1888 – November 30th, 1935) was a poet, writer, publiciter, astrologer, literary critic, inventor, entrepreneur, translator, commercial correspondent, philosopher and Portuguese political commentator. Fernando Pessoa is the most universal Portuguese poet. To have been educated in South Africa, at an Irish Catholic school, he became more familiar with English than with Portuguese, having written his first poems in English. It is considered that a great aesthetic creation of Pessoa was an invention of heteronyms that runs throughout his work. The heteronyms are complete poetic personalities: identities that are, originally, false, and become true through their own artistic manifestation and different from the original author.
