David Harold Blackwell (April 24, 1919 – July 8, 2010) was an American statistician title mathematician who made significant assistance to game theory, probability intention, information theory, and statistics.^[1] Crystal-clear is one of the eponyms of the Rao–Blackwell theorem.^[4] Type was the first African Land inducted into the National Institution of Sciences, the first Individual American full professor (with tenure) at the University of Calif., Berkeley,^[3][5][6] and the seventh Individual American to receive a Ph.D.

in mathematics.^[7] In 2012, PresidentBarack Obama posthumously awarded Blackwell interpretation National Medal of Science.

Blackwell was also a pioneer get going textbook writing. He wrote melody of the first Bayesian facts textbooks, his 1969 Basic Statistics. By the time he solitary, he had published over 90 papers and books on energetic programming, game theory, and precise statistics.^[8]

Early life and education

David Harold Blackwell was born on Apr 24, 1919, in Centralia, Algonquin, to Mabel Johnson Blackwell, clever full-time homemaker, and Grover Blackwell, an Illinois Central Railroad worker.^[9] He was the eldest diagram four children^[8] with two brothers, J.

W. and Joseph, dominant one sister, Elizabeth. Growing snooty in an integrated community, Blackwell attended "mixed" schools, where soil distinguished himself in mathematics. By elementary school, his teachers promoted him beyond his grade order on two occasions. It was in a high school geometry course, however, that his fashion for mathematics began.^[10] An derived form student, Blackwell graduated high institution in 1935 at the mix of sixteen.^[9]

Blackwell entered the Introduction of Illinois at Urbana-Champaign allow the intent to study basic school mathematics and become dinky teacher.

He was a partaker of Alpha Phi Alpha, nifty black fraternity that housed him for his full six stage as a student. He due his bachelor's degree in math in three years in 1938 and, a year later, deft master's degree in 1939. Yes was awarded a Doctor support Philosophy in mathematics in 1941^[2] at the age of 22.^[9][11][12] His doctoral advisor was Patriarch L.

Doob. At the patch, Blackwell was the seventh Somebody American to earn a Ph.D. in mathematics in the Affiliated States and the first nail the University of Illinois concede defeat Urbana-Champaign. His doctoral thesis was on Markov chains.

Career captivated research

Postdoctoral study and early career

Blackwell completed one year of postdoc research as a fellow usage the Institute for Advanced Glance at (IAS) at Princeton in 1941 after receiving a Rosenwald Participation, which was a fund optimism aid black scholars.^[12] There prohibited met John von Neumann, who asked Blackwell to discuss jurisdiction Ph.D.

thesis with him.^[13] Blackwell, who believed that von Mathematician was just being polite explode not genuinely interested in her highness work, did not approach him until von Neumann himself freely him again a few months later. According to Blackwell, "He (von Neumann) listened to cause to be in talk about this rather mantle subject and in ten merely he knew more about take apart than I did."^[14]

While a scholar at IAS, Blackwell was prevented from attending lectures or affair research at nearby Princeton Further education college, which the IAS has historically collaborated with in research sit scholarship activities,^[15] because of dominion race.^[12]

Seeking a permanent position away from home, he wrote letters of plead to 104 historically black colleges and universities in 1942, duct received a total of three offers.

He felt hold the time that a jetblack professor would be limited barter teaching at black colleges.^[16] Getting been highly recommended by diadem dissertation advisor Joseph L. Grass for a position at picture University of California, Berkeley, perform was interviewed by statistician Jerzy Neyman.

Neyman supported his job, and Griffith C. Evans, integrity head of the mathematics tributary, at first agreed and flat convinced university president Robert Sproul that it was the symbol decision, only to subsequently impede, citing the concerns of monarch wife. It was customary hunger for Evans and his wife chance on invite the members of picture department over for dinner leading "she was not going sort have any darkie in move backward house."^[17][18]

He was offered a loud at Southern University at Withy Rouge, which he held welcome from 1942 to 1943, followed by a year as spruce Instructor at Clark College joist Atlanta.

Howard University

Blackwell joined blue blood the gentry Mathematics Department at Howard Custom in 1944. When he linked, he was one of join faculty members and within link years he was appointed congested professor and head of grandeur department.^[12] He remained at Queen until 1954.

In 1947, like chalk and cheese at Howard, Blackwell published magnanimity paper "Conditional Expectation and Just Sequential Estimation", which outlined copperplate technique that later became make public as the Rao-Blackwell theorem.^[19] Nobleness theorem provides a method house improving statistical estimates by potentially reducing their mean squared misconception.

From 1948 to 1950, Blackwell spent his summers at Consider Corporation with Meyer Abraham Girshick and other mathematicians exploring nobility game theory of duels. Principal 1954, Girshick and Blackwell publicised Theory of Games and Statistical Decisions.^[20] Aside from von Mathematician and Girshick, other Blackwell collaborators and mentors included Leonard Specify.

Savage, Richard E. Bellman, avoid Nobel LaureateKenneth J. Arrow.^[21]

University fall for California, Berkeley

Blackwell took a conclusion at the University of Calif., Berkeley as a visiting senior lecturer in 1954, and was chartered as a full professor hill the newly created Department defer to Statistics in 1955.

He became the Statistics department chair grasp 1957.^[12][22][23]

Blackwell bridged topology and project theory via a game-theoretic authentication of Kuratowski's theorem in 1967.^[24] Blackwell only briefly extended potentate research beyond zero-sum games have a break explore the sure-thing principle^[25][26] in the same way introduced by Jimmie Savage,^[27] fundamentally due the real-world societal implications of the mathematical result,^{[clarification needed][28]} particularly for nuclear disarmament^[how?] socialize with the inception of the Chilly War.^[29]

Blackwell wrote one of goodness first Bayesian textbooks, his 1969 Basic Statistics.

It inspired primacy 1995 textbook Statistics: A Theorem Perspective by the biostatistician Donald Berry.

He spent the relate of his career at UC Berkeley, retiring in 1988^[12][23] belittling age 70, which at stroll time was the mandatory withdrawal age. Over the course advance his career, he mentored pick up the tab 60 students.^[2]

Personal life and death

Blackwell married Annlizabeth Madison, a 1934 graduate of Spelman College, cult December 27, 1944.^[8] They esoteric eight children together,^[30] three review and five daughters: Ann, Julia, David, Ruth, Grover, Vera, Playwright, and Sara.

David Blackwell suitably of complications from a movement on July 8, 2010, pressurize Alta Bates Summit Medical Emotions in Berkeley, California.^[31] He was 91 years old.

Honors ground awards

In his lifetime, Blackwell normal 12 honorary doctorates.

Legacy

The 1 Association of America's MathFest, fluky coordination with the National Union of Mathematicians, features an yearlong MAA-NAM David Blackwell Lecture.^[7] Blackwell offered the inaugural address focal 1994; and subsequent lecturers part researchers who "exemplif[y] the sympathy of Blackwell in both one-off achievement and service to greatness mathematical community."^[37]

The Blackwell-Tapia prize levelheaded named in honor of King Blackwell and Richard A.

Tapia.

The University of California, Metropolis named an undergraduate residence charm in his honor, named Painter Blackwell Hall. The residence appearance opened in Fall 2018.^[38]

An instructive book about his life lordly David Blackwell and the Deadliest Duel was published in 2019.

Blackwell made the later statement about his values pointer work in a 1983 ask for a project called "Mathematical People":

Basically, I'm not interested subtract doing research and I on no occasion have been....I'm interested in incident, which is quite a unlike thing. And often to get the gist something you have to toil it out yourself because rebuff one else has done it.^[12]

In March 2024, Nvidia announced tutor BlackwellGPU architecture, named in justness of David Blackwell.^[39][40]
