18542 Broglio           Discovered 1996 Dec. 29 by A. Testa and F. Manca at Sormano.
Luigi Broglio (1911-2001), aereonautical engineer and dean of the aerospace engineering school of the University of Rome "La Sapienza", conceived and directed the San Marco Project, a cooperative space initiative between Italy and the U.S. The Italian space launch facility San Marco was also completed under his direction.
