Andy Chi Headshot

Andrew R. Chi (12 Sep 1920 - 19 June 1982) was born in Tientsin, China. He received the B.S. degree in physics and mathematics from Western Maryland College, Westminster, in 1944, and the M.A. degree in physics from Columbia University, New York, in 1946. He continued graduate studies at Columbia University until 1947.

From 1946 to 1953 he was an Instructor in Physics at the Cooper Union School of Engineering, New York. In 1953 he joined the US Army Signal R&D Labs, Fort Monmouth, N.J., as a Physicist doing research in the fundamental properties of quartz. During 1957-1963 he was employed at the US Naval Research Lab, Washington, D.C., where he was engaged in research studies of atomic resonance devices and precision frequency standards. In 1963 he joined NASA's Goddard Space Flight Center, Greenbelt, M.D., and became Head of the Timing Systems Section, responsible for planning and coordinating all programs pertaining to frequency and time for use by NASA's worldwide satellite tracking and data networks. He was the principal investigator of a joint experiment between NASA and the Federal Aviation Administration on precise time transfer via a synchronous satellite. As such, he planned, developed, and coordinated time synchronization techniques for NASA users.

He was an IEEE Fellow, a member of the American Physical Society and a past member of the American Association of University Professors, American Association of Physics Teachers, Research Society of America, and Philosophical Society of Washington, DC. In addition to the Distinguished Service Award which he received in 1965, Mr. Chi was awarded the Scroll of Appreciation of the Secretary of State for his contributions to CCIR (1967), the Apollo Achievement Award (1969), the Skylab Achievement Award (1974), and the 1978 Moe I. Schneebaum Memorial hard for his significant contributions to the establishment of an international measure of frequency stability.
