Last year in February, I posted some links to famous black mathematicians to highlight their significant contributions to the history of mathematics. This year, I’ll try to highlight some specific individuals. This series starts with David Blackwell, born in 1919 in Illinois.
I devoted a lot of time to Operations Research in the 1990’s. Blackwell’s name really shoots to the top of my memory as he won the von Neumann Theory Prize in 1979 for his work in Markov decision processes. He is also author of the book, ‘Theory of Games and Statistical Decisions’
You can read more about Dr. Blackwell here.
