Roberto Rachewsky was born in 1955, in Porto Alegre, southern Brazil. His great-grandparents came from Bessarabia (Moldova and Ukraine), fleeing the pogroms of Tsar Nicholas II. Belonging to a family of traders, Roberto is the owner of an international logistics company and is an active supporter of laisse-faire capitalism for which he co-founded several institutions to spread the ideas of freedom. He recently published the book "The Greek, the Friar and the Heroine", which deals with the philosophical connection between Aristotle, Thomas Aquinas and Ayn Rand.
