At this site, the original location of Bell Telephone Laboratories, C.J. Davisson and L.H. Germer in 1927 performed the first direct demonstration of the wave-like behavior of the elementary particles, predicted by L. de Broglie in 1923. The Davisson-Germer experiment provided crucial empirical evidence for the validity of the then rapidly evolving theory of quantum mechanics. In those years and subsequently many important scientific and technological discoveries were made at the same laboratory.
