A rich history of invention From the beginning Romanians have been doing things first – including the first recorded human settlement in Europe through to the earliest recorded salt mines 6050BC. Although a small country, there has been a number of Romanian inventions that have changed the world. You will be amazed that you have never heard of these inventors. They make me proud to be a Romanian!

Henri Marie Coanda

Henri Marie Coandă was a Romanian academician and engineer, aviation pioneer, physicist, inventor and discoverer of the effect that has his name. He was the son of General Constantin Coandă, Prime Minister of Romania in 1918.

Inventions and discoveries: - 1911: In Reims, Henri Coandă presents an aircraft with two coupled engines that operated a single propeller. - 1911-1914: Henri Coandă designs several “classic” (propeller) aircraft known as Bristol-Coandă. In 1912, one of them won first prize at the International Military Aviation Competition in England.

With the help of engineer Gustave Eiffel and scientist Paul Painlevé, who helped him obtain the necessary approvals, Henri Coandă performed the experiments and built in Joachim Caproni's workshop the first jet aircraft, in fact a jet aircraft, without propeller, originally called Coandă-1910, which he presented at the second International Aeronautical Show in Paris 1910.

Petrache Poenaru

Poenaru was born on January 10, 1799, in Bănești, Vâlcea County. Fortunately, for the intelligence he showed, the Romanian grew up with more wealthy relatives and was able to continue his studies. In 1827 he received a price for becaming the initiator of the pen. The difference with the previous pens was that it removed the scratches that the pen made on the paper or the ink spills that stained, while ensuring a continuous flow of ink.

Petrache Poenaru can be credited for other things he did, including the fact that he was the first Romanian to travel by train. Being abroad and having access to more information, he hears about the new invention: the train. One month after the launch of the first railway route between Liverpool and Manchester, built in September 1830, Poenaru buys a ticket, and the comments on this new discovery indicate the importance that this meaning of transport has had and still has. "I made this journey with a new mean of transport, which is one of the wonders of the industry… twenty connected carriages, loaded with 240 people are pulled at once by a single steam car…".

Professor Paulescu has been discovering insulin since 1921. The substance that, year after year, saves the lives of millions and millions of people with diabetes.

Nicolae Constantin Paulescu, born on November 8, 1869 in Bucharest, was a Romanian scientist who discovered the antidiabetic hormone secreted by the pancreas, and who was later named insulin.

Nicolae Paulescu has carried out a remarkable scientific research activity in the field of physiology, especially regarding the metabolism of carbohydrates. In 1906 he developed an original method of extirpating the pituitary gland in dogs trans-temporally, which will later be applied in pituitary surgery in humans.

Ana Aslan

Ana Aslan born 1 January 1897, Braila, Kingdom of Romania – died 20 May 1988, Bucharest, Socialist Republic of Romania. She was a Romanian biologist and physician, specialist in gerontology, academician from 1974 and the director of the National Institute of Geriatrics and Gerontology (1958 - 1988).

Ana was the youngest of four children, two brothers and two sisters, born to Margarit and Sofia Aslan. Ana was said to be a very intellectual child, learning to read and write already by age four. At the age of 13, her father died, and her family then moved to Bucharest, Romania. It was in Bucharest where she began her studies. She graduated from the Central School of Bucharest in 1915.

After graduating from the Faculty of Medicine in 1922, she began working with Daniel Danielopolu who supervised her doctoral thesis. She obtained her M.D. degree in cardiovascular physiology in 1924. Her focus was on physiology and the process of ageing. While experimenting on the effects that procaine had on arthritis, Aslan discovered other beneficial effects of this drug. It was this discovery that led to a three-year study and eventual invention of her drug called Gerovital (H3)

Ion Cantacuzino saved the Romanian Army from a real disaster when in 1913, during the Second Balkan War, Romanian troops invaded Bulgaria. Although they occupied the Quadrilateral without a fight, a cholera epidemic broke out among the Romanian troops. The number of deaths was limited thanks to Ion Cantacuzino, who immunized troops with a vaccine he had also discovered. In addition, Romania was, thanks to Ion Cantacuzino, the second country in the world to introduce the vaccination of newborns against tuberculosis. Other diseases such as typhus, typhoid fever or malaria have made fewer and fewer victims from year to year, also thanks to vaccination programs designed by the Romanian scientist.

Ion Cantacuzino was born in 1863, in Bucharest, and was one of the descendants of the Byzantine emperor John IV Cantacuzino. His whole life has been devoted to ensuring the protection and safety of the health of the population, the development of the medical sciences in general, and the prevention and control of infectious diseases, in particular. Even if medicine was not one of his options, Ion Cantacuzino reached a brilliant career in this field, his merits being recognized internationally.
