Born in Milan in 1925, Mario Merz is best known for his sculptures incorporating the Fibonacci numbers in neon lights. His work is well represented in major modern art museums across Europe including Hamurg's Galerie der Gegenwart and London's new Tate museum. Merz's work has also been exhibited in New York's Guggenheim

Mario Merz's installations can also be characterised by his use of found objects, spirals and habitats (eg igloos/tents). His work tends to be of a fairly large scale, and is often best viewed at a distance.

A classic example of his work adorns a wall of the great hall in Zürich hauptbahnhof although some of the neon lights are in need of replacement.

Mario Merz now lives in Turin.
