note = "A major effort on silicon took place at the University of Pennsylvania. In late 1940 or early 1941, physicist Frederick Seitz at Pennsylvania recalls getting a phone call from Lee Du Bridge, Director of the Rad Lab. Du Bridge was worried about problems the Rad Lab was having with commercial grade silicon rectifiers. In consequence, Seitz became involved in developing better silicon rectifiers; a study for which he was granted a contract by the Office of Scientific Research and Development (OSRD).1S",
