- Felix Edouard Justin Emile Borel
.
- Emile Borel's father was Honore Borel who was a Protestant minister.
- Honore Borel himself was the son of a craftsman from Montauben, the capital of Tarn-et-Garonne in the Midi-Pyrenees region.
- At the time Emile was born, his parents were living in a fine eighteenth century house in which Honore Borel had a school for the children of Protestant families in the neighbourhood.
- Honore Borel was an intelligent man and for the first years of his son's life he educated him at home.
- However [',' E F Collingwood, Emile Borel, J.
- Family friends urged Borel to enter the Ecole Polytechnique, which was considered the more prestigious establishment, but he had other ideas.
- Borel was advised that a degree from the Ecole Polytechnique would give him the best opportunities for a job in industry or business.
- The two became firm friends and through the Darboux family Borel came to know leading mathematicians of the day, in particular Emile Picard who he later remarked was a major influence on him at this time.
- Collingwood writes [',' E F Collingwood, Emile Borel, J.
- the theory of measure, Borel's theory of divergent series, his theory of non-analytic continuation and the theory of quasi-analytic functions all derive from ideas which make their first appearance in this paper.
- And it contained the explicit statement and proof of the famous covering theorem which, quite inappropriately, acquired the name of the Heine-Borel theorem ..
- Later Borel spoke about the mathematicians who had influenced him most in his early years mentioning, among others, Camille Jordan, Emile Picard, Paul Appell, Edouard Goursat, Paul Painleve and Marcel Brillouin.
- At almost exactly the same time that he was receiving his doctorate, when still only 22 years of age, Borel was appointed Maitre de Conference at the University of Lille.
- Borel achieved much over the next years, both in his career and in the outstanding mathematics which he produced.
- They had no children but adopted one of Borel's nephews, Fernand Lebeau, the son of his eldest sister who he had lived with while a pupil at the Lycee at Montauben.
- Marguerite Borel was an outstanding author, writing under the pen name Camille Marbo (Marbo being the first three letters of Marguerite and the first two of Borel), and received the distinction of being awarded the Prix Femina in 1913 for La Statue voilee Ⓣ.
- In 1909 Borel was appointed to a chair of Theory of Functions created specially for him at the Sorbonne and he went on to hold this professorship until 1941.
- During World War I he volunteered for military service and commanded an artillery battery [',' E F Collingwood, Emile Borel, J.
- On the fall of Painleve in 1917, Borel returned for a time to the front ..
- In 1928, with financial support from Rockefeller and Rothschild, he set up the Institut Henri Poincare (the Centre Emile Borel is now part of the Institute) and he ran the Institute for thirty years.
- In [',' M Frechet, La vie et l’oeuvre d’Emile Borel, Enseignement mathematique 11 (1965), 1-95.','8] Borel's mathematical work is divided into the following topics: Arithmetic; Numerical series; Set theory; Measure of sets; Rarefaction of a set of measure zero; Real functions of real variables; Complex functions of complex variables; Differential equations; Geometry; Calculus of probabilities; and Mathematical physics.
- Borel created the first effective theory of the measure of sets of points.
- Borel, although not the first to define the sum of a divergent series, was the first to develop a systematic theory for a divergent series which he did in 1899.
- His contributions to this area are described in detail in [',' E Knobloch, Emile Borel as a probabilist, in The probabilist revolution Vol 1 (Cambridge Mass., 1987), 215-233.','9] and we quote here part of the abstract of that paper:-
.
- In addition to many textbooks, Borel published more than fifty papers between 1905 and 1950 on the calculus of probability.
- In addition, between 1921 and 1927, Borel published a series of papers on game theory and became the first to define games of strategy.
- After 1924, Borel became active in the French government serving in the French Chamber of Deputies (1924-36) and as Minister of the Navy (1925-40).

- Also in 1969 Linear algebraic groups was published based on a graduate course given by Borel at Columbia University in the spring of 1968.
- One book which does not seem to be based on a lecture course is Automorphic forms on SL(R) which Borel himself says would have been better titled "Introduction to some aspects of the analytic theory of automorphic forms on SL(R) and the upper half-plane X."

- The last half of the paper is devoted to a more systematic account of the gradual discovery and formulation of the so-called Heine-Borel theorem.
- Borel formulated his theorem for countable coverings in 1895 and Schonflies and Lebesgue generalized it to any type of covering in 1900 and 1898 (published 1904), respectively.

- Edward Van Vleck biography
- In [',' A Novikoff and J Barone, The Borel law of normal numbers, the Borel zero-one law, and the work of Van Vleck, Historia Math.
- It is argued that Van Vleck proved the first zero-one law, anticipating the zero-one law of Borel and, more strikingly, that of Kolmogorov.
- By following Van Vleck's own steps in deriving consequences of his zero-one law, a result ("the extended Van Vleck theorem") is given which is directly comparable to Borel's law of normal numbers.
- Finally, it is shown that the Van Vleck zero-one law, which in generality falls between that of Borel and that of Kolmogorov, is further distinguished in that it provides the key step in establishing what may be the earliest example in ergodic theory of a metrically transitive transformation.
- Lyudmila Vsevolodovna Keldysh biography
- This was a construction of an arithmetic example (using continued fractions) of a set belonging to the fourth Borel class.
- It was the first significant advance in the study of the Borel classification since the first non-trivial example of a third-class set was given by Baire in 1905.
- Keldysh continued to undertake research on the structure of Borel sets and in 1941 she defended her doctoral thesis Structure of B-Sets (Russian).
- First she published the paper Sur la structure des ensembles mesurables B Ⓣ (1944) which summarised her very considerable contributions to the structure of sets of higher Borel class.
- A Russian monograph published in 1945 also gave a detailed description of the results she had obtained over several years concerning the classification of Borel sets in the space of irrational numbers lying in (0, 1).
- Georges Darmois biography
- He was then given the position of 'Agrege preparateur' which was reserved for the most brilliant students, assisting Emile Borel who was director of the Ecole Normale Superieure.
- This came about because Emile Borel, who had set up the course in 1923, had been elected to the Chamber of Deputies in 1925 and looked for someone he could trust to give the course for him.
- At the International Congress of Mathematicians held at Bologna in September 1928, one of the plenary talks was given by Emile Borel who gave the address Le calcul des probabilites et les sciences exactes.
- As well as the Institute of Statistics in Paris, there was also the Institut Henri Poincare set up in 1928, with Borel as its head, to facilitate interactions between researchers in probability and mathematical physics.
- In the second part the general space of states, constituting a Borel field, is considered, with probability defined, as usual, as an additive function of states.
- Georges Valiron biography
- Valiron was awarded a bursary to enable him to study for his doctorate at the Faculty of Science in Paris and he spent the years 1912-14 undertaking research advised by Emile Borel.

- On 18 April 1913, Emile Borel wrote to Volterra that:-
.
- Moreover, on the postcard sent by Borel to Volterra on 1 January 1914 with his best wishes for the new 1914 year (a sentence which sounds strange to the ears of one knowing what was going to happen soon ..
- .), Borel mentioned how he was glad to learn that Volterra was absolutely satisfied with Gateaux in Rome.
- Carlo Bonferroni biography
- While an undergraduate, he read Emile Borel's Elements de la theorie des probabilites Ⓣ and noticed an error that Borel had made in a coin tossing problem.
- He wrote to Borel but never received a reply, although he noticed that Borel corrected the error in the second edition of his book.
- Rolf Nevanlinna (1895-1980)
- He starts with the construction by Weierstrass of an entire function with a preassigned sequence of zeros, the introduction by Laguerre of the genus and the results by Poincare and Hadamard on the link between the exponent of convergence of the zeros and the order of the function which had first been defined by Borel.
- Borel also proved the extension of Picard's theorem which states that the exponent of convergence of the a-points of any entire function is equal to its order except for at most one value of a.
- through R Nevanlinna's successive papers culminating in the monograph 'Le Theoreme de Picard-Borel et la theorie des fonctions meromorphes' Ⓣ(1929).

- The bulk of his work, published between 1939 and 1970, is on topics in the theory of entire and meromorphic functions, where his main tendency is that of generalizing important results, and is grouped in the volume under review into eight sections: (i) "miscellaneous papers", one of which contains generalizations of the theorems of Landau, Schottky, Picard, and of Montel's normality criterion, another on a new method for the summation of power series, but also a paper that falls entirely outside of the realm of analysis (to which all other papers are devoted), answering a question raised by Sierpinski in 1951 on order types; (ii) and (iii), spread over 220 pages, the study of exceptional values of an entire function as influenced by the lacunarity of the Taylor (or Dirichlet) series defining it, (ii) containing F Sunyer i Balaguer's 'Acta Mathematica' paper of 1952; (iv) work on the behaviour of an entire function and its derivatives and primitives along Borel-Valiron directions of maximal type; (v) generalizations of S Mandelbrojt's fundamental inequality (vi) topics in the theory of entire functions and overconvergence; (vii) generalizations of quasi-periodic and elliptic functions; (viii) differentiable functions of a real variable, containing a lovely result (the only one with a co-author, E Corominas) published in 1954) ..

History Topics
- Real numbers 3
- Emile Borel introduced the concept of a normal real number in 1909.
- Borel called a number normal (in base 10) if every k-digit number occurred among all the k digit blocks about 1/10k of the time.
- Now Borel was able to prove that, in one sense, almost every real number was normal.
- However despite proving these facts, Borel couldn't show that any specific number was absolutely normal.
- In 1927 Borel came up with his "know-it-all" number.
- Borel describes k as an unnatural real number, or an "unreal" real.
- Borel devotes a whole book [',' E Borel, Les nombre inaccessible (Gauthier-Villiars, Paris, 1952).','1], which he published in 1952, to discuss another idea, namely that of an "inaccessible number".
- An accessible number, to Borel, is a number which can be described as a mathematical object.
- However, as Borel pointed out, there are a countable number of such descriptions.
- Bourbaki 2
- Armand Borel first became acquainted with the Bourbaki team in 1949.
- He described [',' A Borel, Twenty-Five Years with Nicolas Bourbaki, (1949-1973), Notices Amer.
- Armand Borel, Francois Bruhat, Pierre Cartier, Alexander Grothendieck, Serge Lang, and John Tate are considered the younger members of this third generation.
- Armand Borel explains in [',' A Borel, Twenty-Five Years with Nicolas Bourbaki, (1949-1973), Notices Amer.
- Grothendieck presented to the next Congress a detailed draft of two chapters, the first containing preliminaries to the book on manifolds and categories of manifolds, while the second contained differentiable manifolds, and the differential formalism [',' A Borel, Twenty-Five Years with Nicolas Bourbaki, (1949-1973), Notices Amer.
- For this Armand Borel must take the bulk of the credit for he was the main driving force behind the style and content of this part.

Additional material
- Stäckel's contribution to Mathematics Teaching
- A similar reform movement was taking place in France at around the same time, largely due to Emile Borel, who had written several books in French on the subject.
- Having, as he did, a good command of French, Stackel read, and was impressed by, Borel's books and wanted to make [','T Bohnet, Leben und Werk des Mathematikers Paul Stackel (Staatsexamensarbeit, Karlsruhe University, 1993).','2]:-
.
- He was, however, not content simply to translate Borel's work into German and instead set about reworking the French version into a textbook suitable for a German-speaking audience and for the German education system.
- Statistical Society of Paris
- Note also the presence of Emile Borel who will become President of the Association in 1922 and to whose actions we will return later.
- For two years Emile Borel will teach at the ISUP the calculation of probabilities and its applications to statistics.
- Peres books
- The first half of the work leads us to Descartes and Fermat; The second to the work of Borel, Volterra, etc.
- This volume and the other two in prospect, as well as the recent treatise, "Operations inflnitesimales lineaires," by Volterra and Hostinsky, form an amplification and modernization of the two volumes on functions of curves and integral equations published in the same Borel series on the theory of functions, some twenty-five years ago.
