THE GREATEST CROATIAN SCIENTISTS & TECHNICIANS
Faust Vrančić (1551. – 1617.) Faust Vrančić from Šibenik is a unique
person in the Croatian technique. His greatest work Machinae novae was
published in Venice in 1595. One of the most revolutionary constructions
described in that book, which should certainly be pointed out, was the mill working by the power of wash and tide, really praiseworthy idea. His construction of a parachute, called Homo volans, was completely adequate for the man.
Apart from this book, Vrančić was also famous for creating technical terminology in Croatian language
Marin Getaldić (1568. – 1626.)
He was Croatian mathematician and physicist.
With his work Some ideas about parable and Promoted Archimedes.
he proved for the first time that all forms of parables are suitable for construction of parable mirrors.
Ruđer Bošković (1711. – 1787.) He was one of the greatest Croatian
scientists of all times. He was philosopher, mathematician,
physicist and technician. His masterpiece The theory of
natural philosophy (1758), relationship in nature, which is, as he said himself “based on the law of forces, the only one existing in nature”.
Ferdinand Kovačević (1838. – 1913.) In 1869 he was appointed
vice-president of the The Telegraphic Inspector’s Office Of Croatia and Slavonia in Zagreb
He invented duplex connection which was recognized by The Inovation Office in Vienna in 1892
David Schwartz (1850. – 1897.) inventor of the metal stearable air
balloon or the first zeppelin. he wanted to make stearable aircraft. first inventor who put gasoline engine
into his prototype. he went to Germany, where together
with the factory owner Karl Berg, he found new aluminum alloy called dural (the Schwartz aluminum).
While he was expected to arrive in Berlin, he died in Vienna
His wife sold his invent to Count Zeppelin whose social position contributed that Schwartzplane was recorded in history of inventions as zeppelin
Nikola Tesla (1856. – 1943.) great inventor who worked in the field of electro
technique. His first great invention was the discovery of the
rotating magnetic field. In the year 1884 he worked in Edison’s laboratory He wanted to apply his system of alternating
current (contrary to Edison’s direct current), so he started his own career.
He founded his own laboratory to develop machines of alternating current (which were invented by Tesla himself).
He licensed his invention of system production, transfer and usage of alternating current, system which is used even nowadays.
The American factory owner Westinghouse bought Tesla’s inventions and built the great power plant on the Niagara Falls.
His final aim was wireless transfer of energy, which was also the only idea that he didn’t succeed to realize.
In 1889 he constructed his first high-frequency generators, producing very high voltage in that way.
Andrija Mohorovičić (1857. – 1936.) prominent scientist in the field of seismology,
meteorology and climatology. he reached worldly important discovery. He realized that 54 km deep in the earth
seismic waves suddenly change the speed of spreading.
In that way he discovered the discontinuity line, the border between upper layer of the Earth and the thicker one below.
This discontinuity was called the Mohorovičić’s discontinuity to his honour or the moho layer, expression about the speed change the Mohorovičić’s law
One of the craters on the invisible side of the Moon was also called after him.
Slavoljub Penkala (1871. – 1922.) expert in chemistry and inventor. we will mention few worldly famous
his inventions : ball-pointed pen, fountain pen, pen-holder, rotating tooth brush, wood protective liquid Krepax
He made a sketch for construction of glider hovercraft as well as of helicopter forty five years before the Englishman Cockerel.
top of his work was the construction of the first airplane in Croatia in 1910.
