George H. Heilmeier
George H. Heilmeier was born on May 22, 1936 in Philadelphia, Pennsylvania. He received his BS degree in Electrical Engineering with distinguished honors from the University of Pennsylvania, Philadelphia, and his M.S.E., M.A., and Ph.D. degrees in solid state materials and electronics from Princeton University. In 1958 Heilmeier joined RCA Laboratories in Princeton, New Jersey. There he worked on parametric amplification, tunnel diode down-converters, millimeter wave generation, ferroelectric thin film devise, organic semiconductors, and electro-optic effects in molecular and liquid crystals. In 1964 he discovered several new electro-optic effects in liquid crystals. This led to the first working liquid crystal displays based on what Heilmeier called dynamic scattering mode or DSM.

LCD screens are the medium through which people get their everyday information from. Devices like calculators, clocks, computer monitors, smart phones, and televisions.
