Robert Benjamin Leighton was a prominent American experimental physicist who worked at the California Institute of Technology (Caltech) for his professional career. Over the years, his work spanned solid state physics, cosmic ray physics, the beginnings of modern particle physics, solar physics, planets, infrarot astronomy, and astronomy with millimeter and submillimeter waves. His pioneering work in the latter four fields opened up entirely new areas of research which later evolved into vigorous scientific communities. (Wikipedia) Mr President,
