Born in Tulcea (RO) 10/01/1906 Grigore Constantin Moisil Died in Ottawa (CA) 21/05/1973

Romanian mathematician, computer pioneer, and member of the Romanian Academy. His research was mainly in the fields of mathematical logic, algebraic logic, MV-algebra, and differential equations. He is viewed as the father of computer science in Romania. Moisil was also a member of the Academy of Sciences of Bologna and of the International Institute of Philosophy. In 1996, the IEEE Computer Society awarded him posthumously the Computer Pioneer Award. He played a fundamental role in the development of computer science in Romania, and in raising the first generations of Romanian computer scientists.

Born in Brno (CZ) 28/04/1906 Kurt Gödel Died in New Jersey (US) 14/01/1978

One of the principal founders of the modern, metamathematical era in mathematical logic. He is widely known for his Incompleteness Theorems, which are among the handful of landmark theorems in twentieth century , but his work touched every field of mathematical logic, if it was not in most cases their original stimulus. In his philosophical work Gödel formulated and defended mathematical Platonism, the view that mathematics is a descriptive science, or alternatively the view that the concept of mathematical truth is objective. On the basis of that viewpoint he laid the foundation for the program of conceptual analysis within set theory.

Born in Drobeta-Turnu Severin (RO) 04/10/1873 George Titeca Died in Bucharest (RO) 05/02/1939

Romanian mathematician who made important contributions in geometry. He is recognized as the founder of the Romanian school of differential geometry. Țițeica wrote about 400 articles, of which 96 are scientific projects, most addressing problems of differential geometry. Țițeica discovered a new category of surfaces and a new category of curves which now carry his name. His contributions represent the beginning of a new chapter in mathematics, namely the affine differential geometry. He also studied webs in n-dimensional space, defined through Laplace equations.

Born in Touraine (FR) 31/03/1596 René Descartes Died in Stockholm (SE) 11/02/1650

He was a highly influential French philosopher, mathematician, physicist and writer. He is known for his influential arguments for substance dualism, where mind and body are considered to have distinct essences, one being characterized by thought, the other by spatial extension. He has been dubbed the "Father of Modern Philosophy" and the "Father of Modern Mathematics." He is also known as Cartesius. Descartes first proposed that each point in two dimensions can be described by two numbers on a plane, one giving the point’s horizontal location and the other the vertical location, which have come to be known as Cartesian coordinates.

Born in Jenišovice (CZ) 07/03/1939 Jiří Anděl

One of the most important persons of Czech mathematics and statistics. He is working at Faculty of Mathematics and Physics of Charles University in Prague, where he was studied too. He is the author of ninety scientific papers and seven books written in Czech, two of which have been translated into German. His work is aimed to time series modeling. He has written books for popularization of statistics and probability.

Born in Prague (CZ) 16/05/1935 Petr Vopěnka Died in Prague (CZ) 20/03/2015

He was a Czech mathematician. In the early seventies, he developed alternative set theory (alternative to the classical Cantor theory), which he subsequently developed in a series of articles and monographs. Vopěnka’s name is associated with many mathematical achievements, including Vopěnka's principle. Since the mid-eighties he concerned himself with philosophical questions of mathematics (particularly vis-à-vis Husserlian phenomenology). Vopěnka served as the Minister of Education of the Czech Republic (then part of Czechoslovakia) from 1990 to 1992.

Born in Lemberg (PL) 03/04/1909 Stanislaw Ulam Died in Santa Fe (US) 13/05/1984

One of the most brilliant Polish mathematicians. He was a member of the Lviv School of Mathematics. In the 1930’s he went to the United States and had a very successful career there. He joined the Manhattan Project which was the US's wartime effort to create the atomic bomb. Stanisław Ulam and Edward Teller came up with the Teller–Ulam design, which is the basis for all thermonuclear weapons. Ulam believed that nuclear weapon would deter humans from creating military conflicts. He also discovered the concept of the cellular automaton, invented the Monte Carlo method of computation, and suggested nuclear pulse propulsion.

Born in Basel (CH) 15/04/1707 Leonhard Euler Died in Saint Petersburg (RU) 18/09/1783

Leonhard Euler was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who made important and influential discoveries in many branches of mathematics, such as infinitesimal calculus and graph theory, while also making pioneering contributions to several branches such as and analytic number theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory.
