Biography

David Harold Blackwell (April 24, 1919 – July 8, 2010) was an American statistician and mathematician who made significant contributions to game theory, probability theory, information theory, and statistics. He is one of the eponyms of the Rao–Blackwell theorem, and is also known for the Blackwell channel, Blackwell's contraction mapping theorem, Blackwell's approachability theorem, and the Blackwell order. He wrote one of the first Bayesian statistics textbooks, his 1969 Basic Statistics. He was the first African American inducted into the National Academy of Sciences, the first African American full professor with tenure at the University of California, Berkeley, and the seventh African American to receive a Ph.D. in mathematics.
