Argentina advances to the 2022 World Cup final and prepares to face France. Not only good at football, in the world of science and technology, Argentina has a number of important discoveries.
In many areas of life, Argentine inventions have changed the world, from the simple to the sophisticated. Here are some of the most influential inventions from Argentina.
1. Fingerprint identification
In 1892, Inspector Eduardo Alvarez made the first criminal fingerprint identification. He can identify Francisca Rojas, a woman who killed her two sons and slashed her own throat in an attempt to put the blame on someone else. These findings are used until now, especially in the investigation process.
2. The first artificial heart transplant
The award went to the Argentine physician and inventor Domingo Santo Liotta, who was born in the province of Entre Rios and his colleague Denton Cooley. They developed an artificial heart in 1969, made of plastic fibers and a type of polyester.
3. Collective
A group of taxi drivers in 1928 complained about how little work they had. By accident, they came up with the idea for a vehicle called the colectivo while hanging out at the La Montaña cafe in Rivadavia and Carrasco.
They had the idea of adapting taxi cars to carry more than one passenger. On September 24 of that year, the collectivo became a type of transportation, a kind of typical Argentinian mini bus.
During its development, the term collectivo was used in Argentina, Colombia, Chile and Paraguay for this type of public vehicle. Its name comes from vehÃculos de transporte colectivo, which reflects its origin as a shared taxi.
4. The traffic light sounds
Traffic lights alone are not safe enough for the blind. This is because the blind can only estimate when it is safe to walk, or rely on the help of others who are nearby. Mario Dávila thought of making this innovation in 1983 to help blind people walk independently safely.
5. Ballpoint pen
We must thank Argentina for the invention of the pen. This innovation is very useful and used until now. Its inventor, László József Biró is from Hungary. But he was on Argentine soil when his innovations made the fountain pen a success. László's invention became part of Argentina's national identity and is celebrated as one of the world-changing inventions on Argentina's Inventor's Day every year.
