Barry Gillespie Clark (born March 5, 1938) is an American astronomer who led the development of the world's first digitally recorded, software correlated Very Long Baseline Interferometry (VLBI) system for radio astronomy, the Green Bank Interferometer.[1] He was also heavily involved in the development of the Very Large Array and the Very Long Baseline Array.

Clark earned a BS in 1959 and a PhD in 1964, both from Caltech.[1] His entire working life has been spent at the National Radio Astronomy Observatory in Socorro, New Mexico, where he has worked from 1964-2004, and then from 2004 as Emeritus Scientist (until at least as late as October 2013).[2][3]

Kenneth Kellermann and Marshall Cohen (fellow NRAO scientists) in a 1988 paper, "The origin and evolution of the N.R.A.O.-Cornell VLBI system" discuss much of the work at NRAO on the development of VLBI systems, going from baselines of 200 km to intercontinental baselines, and involving several international collaborations including a collaboration with the USSR.[4]

He is a fellow of the American Astronomical Society (AAS).[5]
