Milan Raspopović

Raspopovic was awarded the Sretenje Order (3rd class) in February 2015, "for special merits for the Republic of Serbia and its citizens in educational and pedagogical activities".

He is also an active writer and continued to revise and publish textbooks for elementary and high schools. In 2010, his books were printed in 200,000 copies, of which more than 150,000 copies were sold before December 2010.

The school held records for winning more than 400 medals at international competitions and Olympiads, and for graduating scientists with approximately 2000 PhD's among its alumni.

Raspopović introduced and developed scientific curricula for two new specializations in Mathematical Gymnasium Belgrade, in 1977: Technician for Nuclear Physics, and Technician for Laser Physics, which both led to the Assistant in Mathematical and Technical Sciences Diploma.

It was not unusual that most, and sometimes all, of the medals at Republics or Federal competitions in Serbia and in Socialist Federative Republic of Yugoslavia, in all categories and for every single grade, were won by students of Mathematical Gymnasium Belgrade. Consequently, Yugoslavian teams for International Olympiads consisted of mostly or only students from Mathematical Gymnasium Belgrade. In 1974, a turbulent year for Yugoslavia when the new Constitution of Yugoslavia was introduced, 7 out of 8 members of Yugoslavian National Team for International Mathematical Olympiad – IMO, were from Mathematical Gymnasium Belgrade. It caused political comment since Yugoslavia had six Republics and seven out of eight students for IMO came from Belgrade's Mathematical Gymnasium. The critics were answered when the Yugoslav team (7 out of 8 were MG students) came back from the IMO with five medals: two gold, one silver, and two bronze. Yugoslavia ranked 5th in the world, and USSR and Yugoslavia were the only 2 countries that won two gold medals that year. Mathematical Gymnasium was the absolute winner among all schools in the world, and remained at that position to the present day. In 2010, the Serbian national team for IMO had MG students only. They ranked 10th in the world as a country (Serbia) and took the first place in the world as a school.

In 1969 he introduced and taught electronics at the Mathematical Gymnasium until 1980.

Raspopović was professor in Mathematical Gymnasium Belgrade from the school's foundation days in 1966, and was elected Principal and Director in 1970. He served as Principal and Director until his retirement, effective from 2002. He was succeeded as a Principal by Ljubomir Protić of the Faculty of Mathematics, University of Belgrade.

Raspopović was the first professor of Physics at Mathematical Gymnasium Belgrade – Special Mathematical Gymnasium (a school of Special National Interest), and the creator of the school's unique physics and overall curriculum. He was one of the founders of the Mathematical Gymnasium Belgrade in Belgrade, along with Vojin Dajović, who was a professor at the Faculty of Natural Sciences and Mathematics, University of Belgrade. Their basic model was Kolmogorov School at Moscow University which had been launched in Moscow a year earlier, in 1965, under Lomonosov Moscow State University, by renowned mathematician Andrei Nikolayevich Kolmogorov, and which was later named after him.

Milan Raspopović (Serbian Cyrillic: Милан Распоповић) was one of the founders of Mathematical Gymnasium Belgrade (abbr. MG) in 1963, the first MG physics professor from 1966, and the creator of the MG Physics Curriculum. He was also an MG professor of electronics, and MG principal and director, elected to office in 1970. Raspopović served in parallel as both Principal and Director of Mathematical Gymnasium Belgrade for 32 years, until his retirement in 2002.
