Ralph R. B. von Frese is an American geologist at the Ohio State University who identified the Wilkes Land crater with Laramie Potts.

In 1969, von Frese obtained a B.A. cum laude from Park College in physics, mathematics and German. He earned M.Sc degrees in physics (1973) and geophysics (1978) and a Ph.D. in geophysics (1980) from Purdue University. He has taught at OSU since 1982.

He and Potts used gravity measurements by NASA's GRACE satellites to identify a 200 mile (300 km) wide mass concentration. This mass anomaly is centered within a larger ring-like structure visible in radar images of the land surface beneath the Antarctic ice cap. This combination suggests that it is the result of a large impact event.[1]
