It is a well-known fact that the scientists from Slavic countries are responsible for a great number of inventions. Thus, it is impossible to list them all, so we picked those you might not have heard about. Everyone knows about Nikola Tesla and his alternating current, but did you know that a sugar cube originally comes from the Czech Republic? Let’s take a look at some of the less popular inventions from Slavic countries.
1. Sugar Cube
A sugar cube is a simple invention widely used all over the world. But not many people know that it was first developed by Jakob Christof Rad, a director of a sugar factory in the Czech Republic.
2. Hive Frame
A hive frame is a core part of a beehive, responsible for holding the honeycomb within the hive. It was invented by Petro Prokopovych, a Ukranian biologist who was also the founder of the commercial beekeeping.
The radiator is a type of a heat exchanger used for the purpose of cooling and heating. It is mostly used in cars and buildings. The first radiator was developed by a Russian businessman and inventor Franz San Galli in 1855.
4. Hair Clippers
Hair clippers are a tool commonly used to cut hair and beard. The first manual hair clippers were invented by a Serbian barber Nikola Bizumić. As a matter of fact, he went all the way to London to get resources for his invention.
5. Modern Contact Lenses
Although the idea of contact lenses was first introduced by the great Leonardo Da Vinci, Czech chemists Otto Wichterle and Drahoslav Lím are responsible for the development of soft contact lenses that provided significantly more comfort than the previous versions.
Esperanto is a popular artificial language constructed by a Polish ophthalmologist Ludwik Zamenhof. His goal was to create an international language that is easy to learn. However, the idea wasn’t as successful as he planned, since only 10 million people worldwide know the language today.
7. Hot Water Bottle
Slavoljub Penkala was a famous Croatian innovator, mostly known for his invention of the mechanical pencil. But what really made him extraordinary is that he is credited with a total of 80 different patents. One that stands out the most is the modern hot water bottle, produced with PVC or natural rubber.
Although materials similar to plastic date all the way back to the 1600 BC, a Serbian inventor Ognjeslav Kostović Stepanović is credited for creating first real plastic in the early 20th century. At the time his creation was called ‘arbonite’.
9. Sailor Cap
Sailor cap is a type of hat worn by sailors in many parts of the world. It was first introduced by Russian Navy in 1811, and it has been a crucial part of the official uniform since then. It was designed for practical reasons, to withstand marine conditions, but it developed into a globally accepted symbol of sailors.
10. Objective Lens
In mid 19th century, a Slovak inventor Joseph Petzval produced a design for an improved photographic objective that would decrease the required exposure time from 30 minutes to less than a minute. A few years later his design started being produced, and the quick snapshots of people and nature were finally available to photographers.
11. 3-D Holography
The Holographic method was developed by a Hungarian physicist Dennis Gabor. However, the method wasn’t put into real practice until 1962, when a Russian inventor Yuri Denisyuk developed the first optical holograms that pictured 3D objects.
12. Modern Parachute
Croatian bishop Faust Vrancic wrote a book Machinae Novenae in 1616, where he included about fifty drawings of various machines. One of them was a developed version of the Leonardo Da Vinci’s simplistic version of the parachute. According to a legend, he tested his invention by jumping from a church in Venice.
13. Powdered Milk
The reason powdered milk was created is that it can be preserved much longer than the regular milk. In 1802, a Russian doctor Osip Krichevsky invented the first contemporary manufacturing process for powdered milk. Thirty years later another Russian scientist, M. Dirchof started organizing its commercialized production.
