Alberto Calderón

Alberto Calderón

Alberto Pedro Calderón (September 14, 1920 – April 16, 1998) was an Argentinian mathematician. His name is associated with the University of Buenos Aires, but first and foremost with the University of Chicago, where Calderón and his mentor, the analyst Antoni Zygmund, developed the theory of singular integral operators. This created the "Chicago School of (hard) Analysis" (sometimes simply known as the "Calderón-Zygmund School").

Calderón's work ranged over a wide variety of topics: from singular integral operators to partial differential equations, from interpolation theory to Cauchy integrals on Lipschitz curves, from ergodic theory to inverse problems in electrical prospection. Calderón's work has also had a powerful impact on practical applications including signal processing, geophysics, and tomography.

Cassius Ionescu-Tulcea

Cassius Tocqueville Ionescu Tulcea (born 14 October 1923 in Bucharest) is a Romanian-American mathematician, specializing in probability theory, statistics and mathematical analysis.

Ionescu Tulcea received his diploma from the University of Bucharest in 1946; there he was an assistant professor from 1946 to 1950, a lecturer from 1950 to 1951, and an associate professor from 1952 to 1957. Additionally, from 1949 to 1957 he was a researcher at the Institute of Mathematics of the Romanian Academy. In 1957 he moved to the United States with his wife Alexandra Ionescu Tulcea (née Bagdasar), who had been his student. From 1957 to 1961 he worked as a research associate and visiting lecturer at Yale University. He received his doctorate from Yale in 1959 under the supervision of Einar Hille with thesis Semi-groups of Operators. Cassius Ionescu Tulcea was from 1959 to 1961 a visiting professor at Yale University, from 1961 to 1964 an associate professor at the University of Pennsylvania, and from 1964 to 1966 a full professor at the University of Illinois at Urbana–Champaign. He became in 1966 a full professor at Northwestern University and retired from there as professor emeritus.

His marriage to Alexandra Ionescu Tulcea lasted from 1956 to 1969 when they divorced. During their marriage, the two mathematicians wrote a number of papers together, as well as a well-regarded research monograph on lifting theory. John von Neumann initiated lifting theory in functional analysis with applications in probability theory. The Ionescu-Tulcea theorem, an important existence theorem for time-discrete stochastic processes, is named after Cassius Ionescu Tulcea (1949). He also did research on mathematical game theory and mathematical economics. He co-authored a book on casino gambling and several textbooks on mathematics; he also wrote a 1981 book on casino dice games and gambling systems and a 1982 book on casino blackjack.

In 1957 he was awarded the Prize of the Romanian Academy of Sciences. His doctoral students include George Maltese and Robert Langlands.

Saul Bellow

Saul Bellow

Saul Bellow (born Solomon Bellows; 10 June 1915 – 5 April 2005) was a Canadian-American writer. For his literary work, Bellow was awarded the Pulitzer Prize, the Nobel Prize for Literature, and the National Medal of Arts. He is the only writer to win the National Book Award for Fiction three times and he received the National Book Foundation's lifetime Medal for Distinguished Contribution to American Letters in 1990.

In the words of the Swedish Nobel Committee, his writing exhibited "the mixture of rich picaresque novel and subtle analysis of our culture, of entertaining adventure, drastic and tragic episodes in quick succession interspersed with philosophic conversation, all developed by a commentator with a witty tongue and penetrating insight into the outer and inner complications that drive us to act, or prevent us from acting, and that can be called the dilemma of our age." His best-known works include The Adventures of Augie March, Henderson the Rain King, Herzog, Mr. Sammler's Planet, Seize the Day, Humboldt's Gift and Ravelstein. Bellow was widely regarded as one of the 20th century's greatest authors.

Bellow said that of all his characters, Eugene Henderson, of Henderson the Rain King, was the one most like himself. Bellow grew up as an immigrant from Quebec. As Christopher Hitchens describes it, Bellow's fiction and principal characters reflect his own yearning for transcendence, a battle "to overcome not just ghetto conditions but also ghetto psychoses." Bellow's protagonists, in one shape or another, all wrestle with what Albert Corde, the dean in The Dean's December, called "the big-scale insanities of the 20th century." This transcendence of the "unutterably dismal" (a phrase from Dangling Man) is achieved, if it can be achieved at all, through a "ferocious assimilation of learning" (Hitchens) and an emphasis on nobility.
