George Harry Heilmeier (May 22, 1936 – April 21, 2014) was an American engineer, manager, and a pioneering contributor to liquid crystal displays (LCDs), for which he was inducted into the National Inventors Hall of Fame.

In 1958 Heilmeier joined RCA Laboratories in Princeton, New Jersey, where he worked on parametric amplification, tunnel diode down-converters, millimeter wave generation, ferroelectric thin film devices, organic semiconductors and electro-optic effects in molecular and liquid crystals.

In 1970–71, he served as a White House Fellow and special assistant to the Secretary of Defense, performing long-range research and development planning.

In December 1977 Heilmeier left government to become vice president at Texas Instruments; in 1983 he was promoted to Chief Technical Officer.

His daughter, Beth Jarvie, said “it was the Christian character of my dad” as well as his ability to put his head down and push forward with the work at hand that played major roles in his contributions.
