Grigore C. Moisil, 19591971 the founding of the Romanian Informatics
"The Informatics/Computer Science restores not only the unity between the pure and the applied mathematical sciences, the concrete technique and the abstract mathematics, but also that between the natural sciences, the human being and the society. It restores the concepts of the abstract and the formal and makes peace between arts and science not only in the scientist' conscience, but in their philosophy as well." Grigore C. Moisil

In 1959 Gr. C. Moisil founded the specialization/section "Computing Machines" (later the Department of Informatics) at the Faculty of Mathematics at University of Bucharest

In 1962 Gr. C. Moisil founded the Computing Center of the University of Bucharest (CCUB) at the Faculty of Mathematics.

In 1968 CCUB, with Moisil's major efforts acquired an American computing system IBM 360/30 and was used to train many generations of computer scientists, contributing to the IT program in Romania.

During 1970/1971, computer science departments (mathematical profile), computer and automation sections (engineering profile) and economic informatics (economics) sections were set up in Bucharest, Cluj, Iaşi and Timişoara.

"The greatest regret of my life is to haven't had any" Grigore C. Moisil

Grigore C. Moisil was born in Tulcea, Romania, in 1906 and died in 1973. His life dedicated to mathematics and computer sciences, consecrated him as an outstanding scientist and professor. He created a school of thought with students and colleagues who continued his work, developing computer science and technology in Romania.

He was a member of the Romanian Academy, of the Academy of Bologna, and of the International Institute of Philosophy. Moisil was a professor of mathematical logic and computer science at the University of Bucharest, and taught in various universities in Europe and America. His early contributions were in mathematics and later he devoted his scientific activity to mathematical logic and computer science. He pioneered the application of mathematical logic to computer science.

In the 1950s, Prof. Moisil developed a new structural theory of finite automata and proposed what he called "the trivalent Lukaszewiczian algebra applied to the logic of switching circuits", an important contribution to the development of computer science in those early years. Some of his books were translated in several languages. At a time when cybernetics was thought of as "reactionary bourgeois science directed against working class" Prof. Moisil used his scientific authority to personally encourage the Romanian scientists to build the first computer, that appeared in 1957.

In 1941, a position of professor at the University of Bucharest opened up, and Moisil applied for it. However, Gheorghe Vrânceanu, Dan Barbilian, and Miron Nicolescu also applied for the position, and Vrânceanu got it. Moisil approached the Ministry of Education, arguing that it would be a great opportunity for mathematics in Romania if all four could be appointed.
 As a result of his appeal, all four mathematicians were hired. Moisil moved to Bucharest, where he became a Professor in the School of Mathematics (later the School of Mathematics and Computer Science) at the University of Bucharest, on 30 December 1941. From 1946 to 1948, Moisil took a leave of absence, being named plenipotentiary envoy to Ankara. While in Turkey, he gave several series of mathematics lectures at Istanbul University and Istanbul Technical University.

In 1959 Gr. C. Moisil founded the specialization/section "Computing Machines" (later the Department of Informatics) at the Faculty of Mathematics at University of Bucharest, and in 1962 founded the Computing Center of the University of Bucharest (CCUB) at the Faculty of Mathematics.
Main Work by Grigore C. Moisil

In 1929 he defended his Ph.D. thesis, La mécanique analytique des systemes continus (Analytical mechanics of continuous systems), before a commission led by Gheorghe Ţiţeica, with Dimitrie Pompeiu and Anton Davidoglu as members. The thesis was published the same year by the GauthierVillars publishing house in Paris, and received favourable comments from Vito Volterra, Tullio LeviCivita, and Paul Lévy.

Professor Moisil published papers on mechanics, mathematical analysis, geometry, algebra and mathematical logic. He developed a multidimensional extension of Pompeiu's areolar derivative, and studied monogenic functions of one hypercomplex variable with applications to mechanics.

Moisil also introduced some manyvalued algebras, which he called Łukasiewicz algebras (now also named Łukasiewicz–Moisil algebras), and used them in logic and the study of automata theory. He created new methods to analyze finite automata, and had many contributions to the field of automata theory in algebra.

Moisil had important contributions in the creation of the first Romanian computers. He played a fundamental role in the development of computer science in Romania, and in raising the first generations of Romanian computer scientists. In 1996, he was awarded by exception posthumously the Computer Pioneer Award by the Institute of Electrical and Electronics Engineers Computer Society.

Professor Moisil famous quotations:

"The most powerful explosive is not the toluene, neither the atomic bomb, but the human idea."

"Science takes its revenge like a woman, not when you attack it, but when you neglect it."

"Unlike the wine, science shouldn't be let to age."

"What's a pessimist? An optimist well informed."

"Nobody should be afraid of abstract things and very abstract things, especially in mathematics; mathematics, precisely because it's mathematics, is abstract. More abstract a thing is, it includes larger fields and so it is aplicable on more concrete situations."

"I don't have a good opinion about children who follow only their parents advice. To have his own personality, the child  and this is valid for student and teacher, too  should part company with his parents and he should act as he wants."

"I believe that one can have professional success only if he is a modest man with daring ideas. We mustn't be misled when we notice that "people who meddle" have success. This apparent success is the one which will bring after a while failure."

"But of course that you need to have in your ideas a great daring and perseverance for the achievement of the purposes for which you aspire through work."

"Mediocrity doesn't forgive the intelligent people for being superficial in appearance and profound in reality."

"The double historical role of foolishness:
1) The foolishness turns the revolution into evolution.
2) the foolishness allows the communications between two intelligence."

“In 1965 Lotfi A. Zadeh published "Fuzzy Sets", his pioneering and controversial paper, that now reaches almost 100,000 citations. All Zadeh’s papers were cited over 185,000 times. Starting from the ideas presented in that paper, Zadeh founded later the Fuzzy Logic theory, that proved to have useful applications, from consumer to industrial intelligent products. We are presenting general aspects of Zadeh’s contributions to the development of Soft Computing(SC) and Artificial Intelligence(AI), and also his important and early influence in the world and in Romania. Several early contributions in fuzzy sets theory were published by Romanian scientists, such as: Grigore C. Moisil (1968), Constantin V. Negoita & Dan A. Ralescu (1974), Dan Butnariu (1978). In this review we refer the papers published in "From Natural Language to Soft Computing: New Paradigms in Artificial Intelligence" (2008, Eds.: L.A. Zadeh, D. Tufis, F.G. Filip, I. Dzitac), and also from the two special issues (SI) of the International Journal of Computers Communications & Control (IJCCC, founded in 2006 by I. Dzitac, F.G. Filip & M.J. Manolescu; L.A. Zadeh joined in 2008 to editorial board). In these two SI, dedicated to the 90th birthday of Lotfi A. Zadeh (2011), and to the 50th anniversary of "Fuzzy Sets" (2015), were published some papers authored by scientists from Algeria, Belgium, Canada, Chile, China, Hungary, Greece, Germany, Japan, Lithuania, Mexico, Pakistan, Romania, Saudi Arabia, Serbia, Spain, Taiwan, UK and USA.”
