Born just outside London at the beginning of World War II, Anthony L. Edridge graduated from the University of Southampton in 1961 and earned his Ph.D. in physics from the University of Surrey. In 1974, he and his family emigrated to Colorado, later moving to Texas, where Edridge attended Hill Country Bible College, graduating in 1981. Returning to research and development, he designed and installed the first cooled millimeter-wave receiver on the radio telescope at the McDonald observatory in west Texas. For the next 20 years, he was employed in engineering management positions, including V.P. of engineering, before retiring in Fort Collins, Colo. He has served as an elder in three evangelical churches since 1975.
