Glenn Brier

Glenn Wilson Brier (26 April 1913 to 2 January 1998) was an American statistician, weather forecaster and academic. He was born in Woodbridge, Virginia, married Josephine Hartz and had three children, Richard Paul, Katherine and David. He earned a Master of Arts degree in statistics from George Washington University and worked for the Office of Meteorological Research of the U.S. Weather Bureau, part of the U.S. Department of Commerce, from 1939 until the 1980s. He is best known for creating a scoring rule that measures the accuracy of forecasts, now called the Brier score, which academics cite widely not only in weather forecasting but across forecasting, decision science and several other fields of research.
