De Finetti, Bruno
(b. Innsbruck, Austria, 13 June ;
d. Rome, Italy, 20 July ), probability theory, statistics, mathematics.
De Finetti was a probability theorist who contributed to statistics, mathematics, financial and actuarial science, and economics. He pioneered the subjectivistic interpretation of probability, according to which probabilities describe a person’s propensity to bet, not objective frequencies independent of humans. He also proved a famous representation theorem concerning exchangeable probability assignments, which ground common patterns of inductive inference.
Although he was born in Austria, de Finetti’s parents were Italian. He pursued his university education in Italy and graduated in mathematics from Milan University in During his academic career he held chairs at Trieste University and the University of Rome. In a long series of publications he promoted the account of subjective probability prominent in decision theory. His views resemble those of Frank Ramsey and Leonard Savage, but he formulated them independently and they have distinctive features. Some probability theorists hold that subjective probabilities are compatible with objective p
de Finetti, Bruno (–)
Bruno de Finetti, an Italian mathematician, was born in Innsbruck, Austria. On the death of his father, the six-year-old de Finetti and his mother moved to Trento (then in Austrian possession). At thirteen he suffered severe osteomyelitis in the left leg; surgery left him permanently lame. In he entered the Politecnico di Milano to study engineering, his father's and grandfather's profession. In his third year he transferred to the new University of Milan, from which he graduated in with a degree in applied mathematics. While still an undergraduate he published the first of a series of articles on Mendelian population genetics, developing the first mathematical model with overlapping generations.
From graduation until de Finetti worked at Rome's Istituto Centrale di Statistica. This was a period of intense and productive research, resulting in publication of a series of mathematical and foundational works on probability. The mathematical works made his name internationally known. The foundational works set out the subjectivist interpretation of probability that he was to advocate all his life.

Bruno de Finetti Biography | ||
| Bruno de Finetti (June 13, - July 20, ) was an Italian probabilist and statistician, noted for the "operational subjective" conception of probability. The classic exposition of his distinctive theory is the "La prévision: ses lois logiques, ses sources subjectives," Annales de l'Institute Henri Poincaré, 7, , which discussed probability founded on the coherence of betting odds and the consequences of exchangeability. De Finetti proposed a thought experiment along the following lines (described in great detail at coherence (philosophical gambling strategy)): You must set the price of a promise to pay $1 if there was life on Mars 1 billion years ago, and $0 if there was not, and tomorrow the answer will be revealed. You know that your opponent will be able to choose either to buy such a promise from you at the price you have set, or require you to buy such a promise from your opponent, still at the same price. In other words: you set the odds, but your opponent decides which side of the bet will be yours. The price you set is the "operational subjective probability" that you assign to the proposition on which you are betting. This Bruno de Finetti

Italian MathematicianBorn in Italy, this renowned mathematician made significant contributions to the fields of probability theory and mathematical statistics. Subjectivist-Operationalist Concept of ProbabilityThe mathematician is famous for developing the "subjectivist-operationalist" concept of probability. This theory posits that probability is not objectively measurable but rather a subjective interpretation based on individual experience and knowledge. De Finetti's ParadoxOne of the mathematician's most notable contributions is "De Finetti's Paradox." This paradox suggests that for an insurance company with limited capital, the probability of its eventual ruin over an infinite time period is equal to one. In other words, it is inevitable that the company will eventually become insolvent.
