Pepe Tanzi (b. 1945) studied at the Politecnico of Milano, where he graduated in architecture in 1969. He started working as an industrial designer with special attention to lighting systems. One of his latest products allows the light to be placed where it is needed, thereby saving energy.Naming citation (20071124/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
