Question: Which of the two Soviet mathematicians was born first, Alexander Gelfond or Aleksandr Danilovich Aleksandrov?

full_context: Document 1: Georgy Adelson-Velsky: Georgy Maximovich Adelson-Velsky (Russian: Гео́ргий Макси́мович Адельсо́н-Ве́льский ; name is sometimes transliterated as Georgii Adelson-Velskii) (8 January 1922 – 26 April 2014) was a Soviet and Israeli mathematician and computer scientist.
Document 2: Pavel Alexandrov: Pavel Sergeyevich Alexandrov (Russian: Па́вел Серге́евич Алекса́ндров ), sometimes romanized Paul Alexandroff or Aleksandrov (7 May 1896 – 16 November 1982), was a Soviet mathematician. He wrote about three hundred papers, making important contributions to set theory and topology.
Document 3: Israel Gelfand: Israel Moiseevich Gelfand, also written Israïl Moyseyovich Gel'fand, or Izrail M. Gelfand (Yiddish: ישראל געלפֿאַנד‎ , Russian: Изра́иль Моисе́евич Гельфа́нд ; 2 September [O.S. 20 August] 1913 – 5 October 2009) was a prominent Soviet mathematician. He made significant contributions to many branches of mathematics, including group theory, representation theory and functional analysis. The recipient of many awards, including the Order of Lenin and the Wolf Prize, he was a Fellow of the Royal Society and professor at Moscow State University and, after immigrating to the United States shortly before his 76th birthday, at Rutgers University.
Document 4: Franz Alexander: Franz Gabriel Alexander, in Hungarian "Alexander Ferenc Gábor", was born in Budapest in 1891, his father was Bernhard Alexander, a philosopher and literary critic, his nephew was Alfréd Rényi, a Hungarian mathematician who made contributions in combinatorics, graph theory, number theory but mostly in probability theory. Alexander studied in Berlin; there he was part of an influential group of German analysts mentored by Karl Abraham, including Karen Horney and Helene Deutsch, and gathered around the Berlin Psychoanalytic Institute. 'In the early 1920s, Oliver Freud was in analysis with Franz Alexander' there — Sigmund Freud's son — while 'Charles Odier, one of the first among French psychoanalysts, was analysed in Berlin by Franz Alexander' as well.
Document 5: Gershgorin circle theorem: In mathematics, the Gershgorin circle theorem may be used to bound the spectrum of a square matrix. It was first published by the Soviet mathematician Semyon Aronovich Gershgorin in 1931. The spelling of S. A. Gershgorin's name has been transliterated in several different ways, including Geršgorin, Gerschgorin, Gershgorin, Hershhorn, and Hirschhorn.
Document 6: Aleksandr Andronov: Aleksandr Aleksandrovich Andronov (Russian: Алекса́ндр Алекса́ндрович Андро́нов ; April 11 [O.S. March 29] 1901 , Moscow – October 31, 1952, Gorky) was a Soviet physicist and member of the Soviet Academy of Sciences (1946). He worked extensively on the theory of stability of dynamical systems, introducing (together with Lev Pontryagin) the notion of structural stability. In that context, he also contributed to the mathematical theory of self-oscillation (a term that he coined) by establishing a link between the generation of oscillations and the theory of Lyapunov stability. He developed the comprehensive theory of self-oscillations by linking it with the qualitative theory of differential equations, topology, and with the general theory of stability of motion. The crater Andronov on the Moon is named after him.
Document 7: Alexander Razborov: Aleksandr Aleksandrovich Razborov (Russian: Алекса́ндр Алекса́ндрович Разбо́ров ; born February 16, 1963), sometimes known as Sasha Razborov, is a Soviet and Russian mathematician and computational theorist.
Document 8: Alexandru Froda: Alexandru Froda (July 16, 1894, Bucharest, Romania – October 7, 1973, Bucharest, Romania) was a well-known Romanian mathematician with important contributions in the field of mathematical analysis, algebra, number theory and rational mechanics. In his 1929 thesis he proved what is now known as Froda's theorem.
Document 9: Aleksandr Danilovich Aleksandrov: Aleksandr Danilovich Aleksandrov (Russian: Алекса́ндр Дани́лович Алекса́ндров , alternative transliterations: "Alexandr" or "Alexander" (first name), and "Alexandrov" (last name)) (August 4, 1912 – July 27, 1999), was a Soviet/Russian mathematician, physicist, philosopher and mountaineer.
Document 10: Alexandrov theorem: In mathematical analysis, the Alexandrov theorem, named after Aleksandr Danilovich Aleksandrov, states that if U is an open subset of R and  "f" : "U" → R   is a convex function, then "f" has a second derivative almost everywhere.
Document 11: Andrey Kolmogorov: Andrey Nikolaevich Kolmogorov (Russian: Андрей Николаевич Колмогоров ; ] , 25 April 1903 – 20 October 1987) was a 20th-century Soviet mathematician who made significant contributions to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory and computational complexity.
Document 12: Baker's theorem: In transcendental number theory, a mathematical discipline, Baker's theorem gives a lower bound for the absolute value of linear combinations of logarithms of algebraic numbers. The result, proved by , subsumed many earlier results in transcendental number theory and solved a problem posed by Alexander Gelfond nearly fifteen years earlier.
Document 13: Alexander Gelfond: Alexander Osipovich Gelfond (Russian: Алекса́ндр О́сипович Ге́льфонд ; 24 October 1906 – 7 November 1968) was a Soviet mathematician. Gelfond's theorem is named after him.
Document 14: Yuri Matiyasevich: Yuri Vladimirovich Matiyasevich, (Russian: Ю́рий Влади́мирович Матиясе́вич ; born March 2, 1947, in Leningrad) is a Russian mathematician and computer scientist. He is best known for his negative solution of Hilbert's tenth problem (Matiyasevich's theorem), which was presented in his doctoral thesis at LOMI (the Leningrad Department of the Steklov Institute of Mathematics).
Document 15: Vladimir Alexandrov: Vladimir Valentinovich Alexandrov (Russian: Владимир Валентинович Александров ; born 1938; disappeared 1985) was a Soviet/Russian physicist who created a mathematical model for the nuclear winter theory. He disappeared while at the Second International Conference of Nuclear Free Zones Local Authorities in Cordoba, Spain on March 31 and his ultimate fate remains unknown, with much speculation continuing. One of his last papers was "Man and Biosphere" published in 1985, it is said to have charted the moving trend in the science of nuclear winter. It was co-authored with Nikita Moiseyev and A.M Tarko.
