Patrick J. Gyger (born 1971 in São Paulo, Brazil) is a Swiss historian, curator and writer. In the 1990s he specialised in medieval studies. Since 1999, he has been the director of Maison d'Ailleurs (translated as "House of Elsewhere"). It is a museum housing one of the world's largest collections of literature relating to science fiction, utopia, and extraordinary journeys. Maison d’Ailleurs is located in Yverdon-les-Bains, Switzerland. It owns over 60,000 books and thousands of pulp magazines, as well as many other items related to science fiction and its imagery. It is also a gallery showing temporary exhibitions exploring the main themes of the field. In 2008, Gyger opened the "Espace Jules Verne", a wing of Maison d'Ailleurs dedicated to Jules Verne and extraordinary journeys. In the early 2000s, Patrick Gyger was one of the co-managers of European Space Agency's ITSF study – Innovative Technologies from Science Fiction for Space Applications – a research looking into Science Fiction to find ideas for space engineers. His most recent book is "Flying Cars or, Memories of a Dreamt Future" (ed. Favre, in French).
