This is a list of Romanian Inventions and Discoveries of Romanian people or inventors/discoverers of Romanian heritage in alphabetical order.
A Ion I. Agârbiceanu: designer of the first gas laser in Romania. Andrei Alexandrescu: pioneering work on policy-based design implemented via template metaprogramming; co-inventor of D programming language. Ana Aslan: inventor of Gerovital, an anti-aging product widely used by famous personalities, such as Charles de Gaulle, John F. Kennedy, Indira Gandhi, Charlie Chaplin and Salvador Dalí. Gheorghe Atanasiu: inventor of infrared monochromator and creator of the method of optical determination of heat of dissociation. Ion Atanasiu: known as the originator of cerimetry, an analytical method based on cerium (IV) as titration reagent.
B
Aurel Babeș: discovered the vaginal smear as screening test for cervical cancer. Victor Babeș: he discovered a parasitic sporozoan of the ticks, named Babesia (of the genus Babesiidae), and which causes a rare and severe disease called babesiosis; he also discovered cellular inclusions in rabies-infected nerve cells. Emanoil Bacaloglu: he is known for the "Bacaloglu pseudosphere". This is a surface of revolution for which the "Bacaloglu curvature" is constant. Radu Bălescu: he worked on the statistical physics of charged particles (Bălescu-Lenard collision operator). Alexandra Bellow: made substantial contributions to the fields of ergodic theory, probability and analysis. George de Bothezat: inventor of the quadrotor helicopter (The Flying Octopus). He is considered one of the founders of aircraft flight dynamics. Ștefan Burileanu: inventor of the Burileanu antiaircraft cannon.
C
Ion Cantacuzino: his discoveries were relevant in the treatment of cholera, epidemic typhus, tuberculosis, and scarlet fever. Elie Carafoli: a pioneering contributor to the field of aerodynamics. Alexandru Ciurcu: invented alongside Just Buisson the reaction engine. Henri Coandă: aircraft designer, discovered the Coandă effect of fluidics. George Constantinescu: founded the Theory of Sonics, based on which he developed a number of applications including a synchronization gear. He is also known as the inventor of a mechanical torque converter, he applied to an experimental automobile as automatic transmission. Justin Capră: engineer and inventor; machines on which he worked included a jetpack, 72 fuel-efficient cars, 15 unconventional engines and seven aircraft, among others.
D Carol Davila: invented the Davila tincture used for the treatment of cholera, an opioid-based oral solution in use for symptomatic management of diarrhea. Anastase Dragomir: he invented the parachuted cell, a dischargeable chair from an aircraft or other vehicle, designed for emergency escapes, an early version of the modern ejection seat.
E Lazăr Edeleanu: he was the first chemist to synthesize amphetamine.
F Alexandru Froda: discovered Froda's theorem.
G Mihai Gavrilă: theoretical quantum physicist, discoverer of atomic dichotomy in ultra-intense, high frequency laser fields. Tudor Ganea: discovered the Eilenberg−Ganea conjecture. Billy Gladstone: among his inventions is the "Ludwig Gladstone Cymbal”, a rare jazz instrument. Rodrig Goliescu: he built the avioplan, the first fixed-wing aircraft with a tubular fuselage and the "Aviocoleopter", the first vertical take-off and landing aircraft. Corneliu E. Giurgea: coined the term nootropics, after discovering Piracetam and describing it as such.
H
Spiru Haret: he made a fundamental contribution to the n-body problem in celestial mechanics by proving that using a third degree approximation for the disturbing forces implies instability of the major axes of the orbits, and by introducing the concept of secular perturbations in relation to this. Horia Hulubei: he is the first physicist to obtain X-ray spectra in gases. He has important contributions in neutron physics and in the study of nuclear reactions.
I Theodor V. Ionescu: the inventor of a multiple-cavity magnetron in 1935, a hydrogen maser in 1947, 3D imaging for cinema/television in 1924 and hot deuterium plasma studies for controlled nuclear fusion in 1969, member of the Romanian Academy since 1955.
L Traian Lalescu: discovered the Lalescu sequence. Constantin Levaditi: alongside Karl Landsteiner, he discovered in 1909 the presence of the polio virus in tissues other than nervous.
M Preda Mihăilescu: known for his proof of Catalan's conjecture. Meinhard E. Mayer: an early contributor to the theory of vector-bosons (W and Z bosons) and electro-weak unification, which later became the Standard Model, and an early advocate of the use of fiber bundles in gauge theory. Mina Minovici: famous for his extensive research regarding cadaverous alkaloids, putrefaction, simulated mind diseases, and criminal anthropology. Grigore Moisil: discovered Łukasiewicz-Moisil algebras, and he was elected a Member of the Romanian Academy Florentina I. Mosora: Romanian biophysicist who worked at first in the "Carol Davila" School of Medicine of the University of Bucharest, and subsequently in Belgium at the University of Liege; specialized in Nuclear Medicine, she applied nuclear medicine techniques and invented new methodology for the clinical investigation of type 2 diabetes.
N
Mihai Nadin: he founded the world's first program in Computational Design. Costin D. Nenițescu: he found new methods for the synthesis of pirilium salts, of carbenes, tryptamine, serotonin, two new syntheses for the indole nucleus, and a new method of polymerisation of ethylene.
O
Hermann Oberth: along with the Russian Konstantin Tsiolkovsky and the American Robert Goddard, one of the founding fathers of rocketry and astronautics. Ștefan Odobleja: had supposedly established many of the major themes of cybernetics regarding cybernetics and systems thinking ten years before the work of Norbert Wiener was published in 1948.
