A mining school called "Berg Schola", the world's first institute of technology was founded in Selmecbánya, Kingdom of Hungary{{cite web |url=http://oldwww.uni-miskolc.hu/uni/univ/booklet/MandU.html |title=Miskolc and the University |access-date=2014-01-28 |url-status=dead |archive-url=https://web.archive.org/web/20120301055508/http://oldwww.uni-miskolc.hu/uni/univ/booklet/MandU.html |archive-date=2012-03-01 }} (today Banská Štiavnica, Slovakia), in 1735. Its legal successor is the University of Miskolc and the University of Sopron in Hungary.

BME University is considered the world's oldest institute of technology which has university rank and structure. It was the first institute in Europe to train engineers at university level.{{cite web |url=http://www.moveonnet.eu/directory/institution?id=HUBUDAPES02 |title=Budapesti Műszaki és Gazdaságtudományi Egyetem (Budapest University of Technology and Economics) — moveonnet |access-date=2012-06-11 |url-status=dead |archive-url=https://web.archive.org/web/20121119002524/http://www.moveonnet.eu/directory/institution?id=HUBUDAPES02 |archive-date=2012-11-19 }}

Among Hungary's numerous research universities, the Eötvös Loránd University, founded in 1635, is one of the largest and the most prestigious{{Cite book|title = Language Planning and Policy in Europe|url = https://books.google.com/books?id=ei6TGveKcuEC|publisher = Multilingual Matters|date = 2005-01-01|isbn = 978-1-85359-811-1|language = en|first1 = Robert B.|last1 = Kaplan|first2 = Richard B.|last2 = Baldauf}} public higher education institutions in Hungary. The 28,000 students at ELTE are organized into eight faculties, and into research institutes located throughout Budapest. ELTE is affiliated with 5 Nobel laureates, as well as winners of the Wolf Prize, Fulkerson Prize and Abel Prize, the latest of which was Abel Prize winner Endre Szemerédi in 2012.

Semmelweis University in the recently released QS World University Rankings 2016 listed among the world's best 151–200 universities in the categories of medicine and pharmacy. According to the international ranking in the field of medicine Semmelweis University ranked first among the Hungarian universities. The "Modern Medical Technologies at Semmelweis University" project ensuring institution's place among the leading research universities in four main areas: Personalised medicine; Imaging processes and bioimaging: from molecule to the human being; Bio-engineering and nanomedicine; Molecular medicine.

Budapest University of Technology and Economics's research activities encouraged and is present on all levels from the B.Sc. through to the doctoral level. During the 1980s the BUTE was among the first in the Eastern bloc to recognise the importance of participating in research activities with institutions in Western Europe. Consequently, the university has the most well-established research relationships with Western European universities. There are many famous alumni at university: Dennis Gabor who was the inventor of holography got his Nobel Prize in Physics in 1971, George Oláh got his Nobel Prize in Chemistry in 1994. Nowadays the university has 110 departments, 1100 lecturers, 400 researchers.

University of Szeged internationally acknowledged, competitive research activities are essential parts of its educational mission, and it is particularly important to ensure the institution's position as a research university. Its research and creative activities include basic and applied research, creative arts, product and service development.

University of Debrecen with a student body of about 30 thousand is one of the largest institutions of higher education in Hungary and its priority areas of research include: molecular science; physical, computational and material science; medical, health, environmental and agricultural science; linguistics, culture and bioethics.

University of Pécs is one of the leading research universities in the country with a huge professional research background. The Szentágothai Research Centre of the University of Pécs is covers all aspects of education, research and innovation in the fields of biomedical, natural and environmental sciences. The infrastructure, instrumentation and expertise of the 22 research groups operating on the premises provide an excellent basis to become a well-known, leading research facility in Hungary as well as in Central Europe with an extensive and fruitful collaboration network.

Hungarian Academy of Sciences's research network also contributes significantly to research output of Hungary. It comprises 15 legally independent research institutions and more than 130 research groups at universities co-financed by the academy. This research network focusing above all on discovery research is unparalleled in Hungary, accounting for one-third of all scientific publications produced in the country. Citation indices of publications posted by the academy's researchers surpass the Hungarian average by 25.5%. The research network addresses discovery and targeted research, in cooperation with universities and corporations. The main components of the network are the MTA Szeged Research Centre for Biology, the MTA Institute for Computer Science and Control, the MTA Rényi Institute of Mathematics, the MTA Research Centre for Natural Sciences, the MTA Institute of Nuclear Research, the MTA Institute of Experimental Medicine, MTA Wigner Research Centre for Physics, the MTA Centre for Energy Research and MTA Research Centre for Astronomy and Earth Sciences (involved with Konkoly Observatory).{{cite news| url=http://mta.hu/english/mtas-research-centres-and-institutes-106085| work=Hungarian Academy of Sciences | title=MTA's Research Centres and Institutes}}

According to the HVCA (Hungarian Venture Capital and Private Equity Association) report joint efforts of the venture capital and private equity industry and the Hungarian government, the access of Hungarian enterprises to venture capital and private equity funding could be significantly increased. During the past two decades these financial intermediaries have also played an increasingly important role in the Hungarian economy. During this period, venture capital and private equity funds invested close to 4 billion US Dollars into more than 400 Hungarian enterprises.

However, so-called buyout transactions have accounted for about two thirds of the total volume of those investments, which were aimed at the acquisition of shares in mature companies that have been operating profitably for several years. The volume of investments in early and expansive stage companies was significantly lower. Only about 30% of the total volume of investments was directed at companies in the expansive stage and less than 5% at early stage companies. This is also reflected by the fact that over the last two decades slightly more than 10% of the total volume of venture capital and private equity investments came from funds focusing on early stage companies. The remaining close to 90% was invested by private equity funds focusing on more mature companies with greater economic strength. As for the number of transactions, companies in the expansive stage were targeted by the largest number of venture capital and private equity investments: such investments accounted for almost 60% of Hungarian transactions. Nearly a third of transactions involved early stage companies. Buy-out deals represented approximately 10% of transactions by number. Several factors have contributed to this growth. These include tax exemptions on Hungarian venture capital, funds established in conjunction with large international banks and financial companies and the involvement of major organizations desirous to capitalize on the strengths of Hungarian start up and high-tech companies. In recent years, the share of venture capital invested in the growth stages of enterprises has flourished at the expense of early stage investments.{{cite news| url=http://cee-startups.com/hungary-2/venture-capital-and-private-equity-industry-in-hungary-extract-of-the-hvca-report-on-the-vc-and-pe-industry-in-hungary/| work=Balázs Szabó | title=Venture Capital and Private Equity industry in Hungary}}

Since the first Hungarian won a Nobel Prize in 1905, the country has added a further 14 to its cache.{{cite news| url=http://mta.hu/english/hungarys-nobel-prize-winners-106018| work=Hungarian Academy of Sciences | title=Hungary's Nobel Prize Winners}} With scientists, writers and economists all honored in the prestigious awards:

Hungary has excelled at the scientific Olympiads, ever since the beginnings.

Best result is in maths with absolute cumulative 4th place until 2019, behind China, Russia and US. Per capita result is a world leader.{{Cite web|url=https://www.youtube.com/watch?v=38xeYPAUPd0|title=Top 20 Country by International Mathematical Olympiad Gold Medal (1959–2019)|date=11 December 2019|via=YouTube}}

Results in physics is just somewhat weaker. 9th place (3rd best in Europe). Per capita result is also a world leader.

Chemistry (1968–2019) results give 8th place and 4th place in Europe. This is also a world leader per capita.

However the results have weakened lately.

In August 1939, Szilárd approached his old friend and collaborator Albert Einstein and convinced him to sign the Einstein–Szilárd letter, lending the weight of Einstein's fame to the proposal. The letter led directly to the establishment of research into nuclear fission by the U.S. government and ultimately to the creation of the Manhattan Project. (Szilárd, with Enrico Fermi, patented the nuclear reactor).

Important names in the 18th century are Maximilian Hell (astronomer), János Sajnovics (linguist), Matthias Bel (polyhistor), Sámuel Mikoviny (engineer) and Wolfgang von Kempelen (polyhistor and co-founder of comparative linguistics). Physicist and engineer Ányos Jedlik invented the first electric motor (1828), the dynamo, self-excitation, the impulse generator, and the cascade connection of capacitors. An important name in 19th-century physics is Joseph Petzval, one of the founders of modern optics. The invention of the transformer (by Ottó Bláthy, Miksa Déri and Károly Zipernowsky), the AC electricity meter, and electricity distribution systems with parallel-connected power sources decided the future of electrification in the war of the currents, which resulted in the global triumph of alternating current systems over the earlier direct current systems.

Kövesligethy made several assumptions on the matter-radiation interaction. Based on these assumptions, he derived a spectral equation with the following properties: the spectral distribution of radiation depends only on the temperature, the total irradiated energy is finite (15 years before Planck!), the wavelength of the intensity maximum is inversely proportional to the temperature (eight years before Wien!). Using his spectral equation, he estimated the temperature of several celestial bodies, including the Sun. As a byproduct he developed a theory of the spectroscopic instruments

{{Main|Hungarian mathematics}}

Hungary is famous for its excellent mathematics education, which has trained numerous outstanding scientists. Famous Hungarian mathematicians include father Farkas Bolyai and son János Bolyai, designer of modern geometry (non-Euclidean geometry) 1820–1823. Together with John von Neumann, János Bolyai is considered to be the greatest Hungarian mathematician ever. The most prestigious Hungarian scientific award is named in honor of János Bolyai. John von Neumann was a pioneer in quantum theory, game theory and digital computing, and he was the key mathematician on the Manhattan Project. Mathematician Paul Erdős is famed for publishing in over forty languages, and his Erdős numbers are still tracked.[http://www.hungemb.com/damascus/hungarians_to_universal_culture.htm The Contribution of Hungarians to Universal Culture] {{webarchive|url=https://archive.today/20070502084555/http://www.hungemb.com/damascus/hungarians_to_universal_culture.htm |date=2007-05-02 }} (includes inventors), Embassy of the Republic of Hungary, Damascus, Syria, 2006.

Many Hungarian scientists, including Zoltán Bay, Victor Szebehely (practical solution to the three-body problem; Newton the two-body problem), Mária Telkes, Imre Izsak, Louis W. Parker, Erdős, von Neumann, Leó Szilárd, Eugene Wigner, Theodore von Kármán and Edward Teller, emigrated to the United States and made valuable contributions there. (Some Hungarian scientists went to Germany instead: engineer/scientist István Szabó (1906–1980), for example.{{Cite book | url=https://books.google.com/books?id=EBfzBQAAQBAJ&pg=PA185 |title="The shoulders on which we stand"-Wegbereiter der Wissenschaft: 125 Jahre Technische Universität Berlin|isbn = 978-3-642-18916-6|last1 = Knobloch|first1 = Eberhard|date = 2013-03-11|publisher=Springer }}

Locomotive engine and railway vehicle manufacturers before World War One (engines and wagons, bridge and iron structures) were the MÁVAG company in Budapest (steam engines and wagons) and the Ganz company in Budapest (steam engines, wagons, the production of electric locomotives and electric trams started from 1894).{{cite web |url= http://www.sztnh.gov.hu/English/feltalalok/kando.html |title=HIPO HIPO – KÁLMÁN KANDÓ (1869–1931) |publisher=Sztnh.gov.hu |date=2004-01-29 |access-date=2013-03-25}} and the RÁBA Company in Győr.

The Ganz Works identified the significance of induction motors and synchronous motors commissioned Kálmán Kandó (1869–1931) to develop it. In 1894, Kálmán Kandó developed high-voltage three-phase AC motors and generators for electric locomotives. The first-ever electric rail vehicle manufactured by Ganz Works was a 6 HP pit locomotive with direct current traction system. The first Ganz made asynchronous rail vehicles (altogether 2 pieces) were supplied in 1898 to Évian-les-Bains (Switzerland), with a {{convert|37|hp |adj=on}}, asynchronous-traction system.

The M1 line became an IEEE Milestone due to the radically new innovations in its era: "Among the railway’s innovative elements were bidirectional tram cars; electric lighting in the subway stations and tram cars; and an overhead wire structure instead of a third-rail system for power."Budapest’s Electric Underground Railway Is Still Running After More Than 120 Years [https://spectrum.ieee.org/budapests-electric-underground-railway-is-still-running-after-more-than-120-years]

The spread of the Industrial Revolution in Hungary, along with the technological changes brought about by progress, made it clear by the end of the 19th century that the end of horse-drawn transport was approaching. Around 1818, Farkas Bolyai and Péter Bodor presented their steam carriage in Marosvásárhely, in 1819, József Horti-Horváth showcased the flywheel omnibus, Ányos Jedlik stirred the interest with his electric-powered vehicle model and carriage. Developments continued in the latter half of the century: in 1876, György Wessely received a patent for a self-propelled steam carriage, and Ferenc Preiner also demonstrated a steam-powered carriage. By 1890, Ferenc Korda had created the first battery-operated electric car in Hungary. János Csonka had a significant impact on further development in the industrial sector of petrol engines; in addition to inventing the carburetor, he designed a petrol engine driven mail collection car for the Hungarian Post. The vehicle was manufactured by the Ganz company and was put into circulation in November 1900.[https://mek.oszk.hu/02100/02185/html/784.html Antal Emanuel: Magyarország a XX. században (2000)]

Power plants, generators and transformers

In 1878, the Ganz company's general manager András Mechwart (1853–1942) founded the Department of Electrical Engineering headed by Károly Zipernowsky (1860–1939). Engineers Miksa Déri (1854–1938) and Ottó Bláthy (1860–1939) also worked at the department producing direct-current machines and arc lamps.

In autumn 1884, Károly Zipernowsky, Ottó Bláthy and Miksa Déri (ZBD), three engineers associated with the Ganz factory, had determined that open-core devices were impracticable, as they were incapable of reliably regulating voltage.Hughes, p. 95 In their joint 1885 patent applications for novel transformers (later called ZBD transformers), they described two designs with closed magnetic circuits where copper windings were either a) wound around iron wire ring core or b) surrounded by iron wire core.{{cite book|url=https://archive.org/details/historyoftransfo00upperich|last=Uppenborn|first=F.

The ZBD patents included two other major interrelated innovations: one concerning the use of parallel connected, instead of series connected, utilization loads, the other concerning the ability to have high turns ratio transformers such that the supply network voltage could be much higher (initially 1,400 to 2,000 V) than the voltage of utilization loads (100 V initially preferred).{{cite web|title=Hungarian Inventors and Their Inventions|url=http://www.institutoideal.org/conteudo_eng.php?&sys=biblioteca_eng&arquivo=1&artigo=94&ano=2008|publisher=Institute for Developing Alternative Energy in Latin America|access-date=Mar 3, 2012|url-status=dead|archive-url=https://web.archive.org/web/20120322223457/http://www.institutoideal.org/conteudo_eng.php?&sys=biblioteca_eng&arquivo=1&artigo=94&ano=2008|archive-date=2012-03-22}}{{cite web|title=Bláthy, Ottó Titusz|url=http://www.omikk.bme.hu/archivum/angol/htm/blathy_o.htm|publisher=Budapest University of Technology and Economics, National Technical Information Centre and Library|access-date=Feb 29, 2012}} When employed in parallel connected electric distribution systems, closed-core transformers finally made it technically and economically feasible to provide electric power for lighting in homes, businesses and public spaces.{{cite web|title=Bláthy, Ottó Titusz (1860–1939)|url=http://www.hpo.hu/English/feltalalok/blathy.html|publisher=Hungarian Patent Office

Light bulbs, radio tubes and X-ray

Tungsram is a Hungarian manufacturer of light bulbs and vacuum tubes since 1896.

On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for the world's first tungsten filament lamp. The tungsten filament lasted longer and gave brighter light than the traditional carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries.{{cite web |url=http://www.tungsram.hu/tungsram/downloads/tungsram/tu_short_history_1896-1996.pdf |date=4 Aug 1998 |access-date=2023-06-15 |title=Rövid történet |language=en, hu |trans-title=A Short History |archive-url=https://web.archive.org/web/20050530094858/http://www.tungsram.hu/tungsram/downloads/tungsram/tu_short_history_1896-1996.pdf |archive-date=30 May 2005}} Their experiments also showed that the luminosity of bulbs filled with an inert gas was higher than in vacuum. The tungsten filament outlasted all other types (especially the former carbon filaments). The British Tungsram Radio Works was a subsidiary of the Hungarian Tungsram in pre-WW2 days.

Despite the long experimentation with vacuum tubes at Tungsram company, the mass production of radio tubes begun during WW1,See: The History of Tungsram 1896–1945" Page: 32 and the production of X-ray tubes started also during the WW1 in Tungsram Company.See: The History of Tungsram 1896–1945" Page: 33

signal generators, oscilloscopes and pulse generators

The signal generators, oscilloscopes and pulse generators manufactured by Orion's instrumentation class have done a good job for the domestic industry as well as for export.

Home appliances

The Orion Electronics was founded in 1913. Its main profiles were the production of electrical switches, sockets, wires, incandescent lamps, electric fans, electric kettles, and various household electronics.

Industrial Refrigerators

In 1894, Hungarian inventor and industrialist István Röck started to manufacture an industrial ammonia refrigerator which was powered by electric compressors (together with the Esslingen Machine Works). At the 1896 Millennium Exhibition, Röck and the Esslingen Machine Works presented a 6-tonne capacity artificial ice producing plant. Until nationalisation after the Second World War, large-scale refrigerator production in Hungary was in the hands of Röck and Ganz Works. In 1906, the first Hungarian cold store (with a capacity of 3,000 tonnes, the largest in Europe) opened in Tóth Kálmán Street, Budapest.[https://web.archive.org/web/20220506202421/https://mek.oszk.hu/02100/02185/html/703.html The development and heyday of mechanical science (Hungarian) Link]
