David Blackwell is a famous African-American mathematician who has contributed so much in the field of mathematics in the statisticalfield theory. David was born in 1919 in Illinois. He died in 2010 at the age of 91. He was born to a father who was a worker in a railway station and his mother was s stay at home mum who took care of his younger siblings because he was the first born. The statistician theorist was born in a family of six. He was very apt when it came to mathematics, though he did not concentrate so much on algebra and trigonometry which he says that though he could be able to do it, it was not much more intriguingfor him to do such topics, what he has been so much interested in was geometry since it connected with activity as well as motion. He asserted loving the idea of a helping line where a problem would be solved, that seemed previously impossible.
[...] Here, he provided practical examples of how to integrate the two. He also discovered the discreteness of Ferguson selections in the year 1973. Further to that, he discovered much in the gaming world through his work on Infinite games and Analytics sets. Later, he also discovered a set in Borel's Theorem, which did not contain a graph between 1968. He also discovered the information theory in 1961. (David, 1961)This has changed the thinking of many statisticians. Works cited Berkely.edu. "Blackwell Biography." 12 June 2009. Berkely.edu. Document March 205. Crimes, William. [...]
[...] David Blackwell came up with various discoveries as a mathematical scholar. Most of the discoveries that he came up with were in the field of statistics and probability.His first discovery was on the Equation of Wald which he wrote in the year 1946. The discovery was based on proving Wald's theorem under weaker conditions than it had previously been proven. On this theorem, he proved that the convergence of large numbers is true and that the expected value of each S1 must be infinite, so that they must converge to the expectation of E this scholar also worked on the Minimax versus Bayes Prediction.

[...] His interest in statistics was much provoked by a talk which was made by Abe Girshik on the sequential analysis and that changed the way that Blackwell visualized sampling. The normal practice where scientists limit their samples before they started working, on this, Abe Girshik proposed that the scientists should sample until they see enough. Through this, David saw statistics being applied in a real life situation which intrigued him. During the presentation, Abe proposed a theory which Blackwell did not contend with. [...]

[...] At only sixteen years, David Blackwell started his degree in mathematics at Illinois University. The parents were convinced that the children would join college, but they had less to do with the courses that they took. Considering that his father was a worker in a railway station, the money they shared in the family was not always enough for all his needs to be met. With this, he had to workas a cleaner in several occasions to make through the college. [...]
