James Robert Biard (May 20, 1931 – September 23, 2022) was an American electrical engineer and inventor who held 73 U.S. patents. Some of his more significant patents include the first infrared light-emitting diode (LED),[1] the optical isolator,[2] Schottky clamped logic circuits,[3] silicon Metal Oxide Semiconductor Read Only Memory (MOS ROM),[4] a low bulk leakage current avalanche photodetector, and fiber-optic data links. In 1980, Biard became a member of the staff of Texas A&M University as an adjunct professor of electrical engineering. In 1991, he was elected as a member into the National Academy of Engineering for contributions to semiconductor light-emitting diodes and lasers, Schottky-clamped logic, and read-only memories.
