A couple of weeks ago I was talking with a friend about famous mathematicians. First I have to say that he is from Italy and we had a wonderful talk about Italian mathematicians. During the talk we discussed about French mathematicians, Russian ones, British ones and more. At some point during the discussion he asked me about Romanian mathematicians ( for those of you that don’t know I am from Romania) and I couldn’t answer his questions, I didn’t know any mathematicians. At that point I felt bad and quite ashamed I didn’t know anyone, so I decided to do some research and find out more about Romanian mathematicians and here are my favorite ones. Enjoy ^_^

**1. Titu Andreescu **– is an associate professor of mathematics at the University of Texas at Dallas. He is also firmly involved in mathematics contests and olympiads, having been the Director of American Mathematics Competitions, Director of Mathematical Olympiad Program, Head Coach of the USA International Mathematical Olympiad, Team and Chairman of the USA Mathematical Olympiad. He has also authored a large number of books on the topic of problem solving and olympiad style mathematics.

During the 1980s, Titu Andreescu served as a coach for the Romanian IMO team and in 1983 was presented with the national award of “Distinguished Professor”. In 1984 he was appointed as “Counselor of the Romanian Ministry of Education”. After emigrating to America, Andreescu became involved in Coaching the American IMO team. His most notable success in came in 1994 when the American team obtained a perfect score at the Hong Kong International Mathematical Olympiad, the first time that any team had achieved this. In recognition of this, Titu was awarded a Certificate of Appreciation from the Mathematical Association of America for “outstanding service” as coach of the USA Mathematical Olympiad Program. Moreover, he started a lot of programs for children: AwesomeMath Program, Metroxplex Math Circle and Math Rocks! Program.

**2. Alexandra Ionescu Tulcea – **is a mathematician from Bucharest, Romania, who has made substantial contributions to the fields of ergodic theory, probability and analysis.

During her marriage to Ionescu Tulcea (1956–1969) she and her husband wrote a number of papers together, as well as the research monograph on Lifting Theory. Some of her early work involved properties and consequences of lifting. Lifting theory, which had started with the pioneering paper’s of John von Neumann and later Dorothy Maharam, came into its own in the 1960s and 70’s with the work of the Ionescu Tulceas and provided the definitive treatment for the representation theory of linear operators arising in probability, the process of disintegration of measures. The Ergebnisse monograph became a standard reference in this area.

**3. Grigore Constantin Moisil – **was a Romanian mathematician, computer pioneer, and member of the Romanian Academy. His research was mainly in the fields of mathematical logic, (Łukasiewicz–Moisil algebra), algebraic logic, MV-algebra, and differential equations. He is viewed as the father of computer science in Romania.

Moisil published papers on mechanics, mathematical analysis, geometry, algebra and mathematical logic. He also introduced some many-valued 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.

**4. Octav Onicescu – **was a Romanian mathematician, member of the Romanian Academy, and founder of the Romanian school of probability theory and statistics. He will the last on my list today due to the fact that he was born in the same city I was born ( Botoşani ) and also he went to the same high-school as me (August Treboniu Laurian Lyceum). During school, every year I participated in the mathematical competition named with his name and I always enjoyed it.

In 1924, he started teaching the first college-level probability theory course in Romania. From 1928 on, he was professor at the Faculty of Sciences of the University of Bucharest, and was appointed full professor in 1931. In 1930, he organized the School of Statistics and established an Institute of Calculus, serving as its director for many years. He was elected corresponding member of the Romanian Academy in 1933, and became full member on February 4, 1965. He was in charge of the Probability Theory section of the Institute of Mathematics of the Romanian Academy.

I hope you found this article interesting. These are not all the Romanian mathematicians, but are the ones that I have found more interesting. Thank you for your support. Thank you for your help and support. Thank you for reading. You can find me on Facebook, Tumblr, Google+, Twitter, Instagram and Lettrs, I will try to post there as often as possible. *Don’t forget that maths is everywhere! Enjoy! *

As a collector of stamps on the subject of mathematics there are very many envelopes and stamps about Romanian mathematics (say in comparison with Italy). If anyone is interested I can send some scans.

This is incredible 🙂 I would love to see some scans with Romanian mathematicians 😉 if there is not much to ask can you also send me some other scans with maybe your favourite ones. Email: lthmathematics @gmail.com
