This world famous inventor, best known by designing the modern alternating current electricity supply system, was born in Croatian village Smiljan in the Lika region. He moved to the United States in 1884 to work for Thomas Edison in New York. Although his work fell into relative obscurity after his death, in 1960 the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor.

Ivan Vucetic was the founder of dactylography , the science of using fingerprints to uniquely identify someone. Vucetic was born on the Croatian island of Hvar in the Dalmatia region in 1858, then part of the Habsburg Monarchy.

Rudjer Boskovic, born in 1711, was a physicist, astronomer, mathematician, philosopher, diplomat, poet and a polymath from Dubrovnik. He produced a precursor of atomic theory and made many contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.
Also known as Ivan Lupis, Vukic was born in Rijeka in 1813, and is best known for developing the first prototype of the self-propelled torpedo. British machine engineer Robert Whitehead perfected the design, which then became the standard equipment of navies across the world.

Marcel Kiepach from Krizecvi patented a dynamo for vehicle lighting. It was an electric generator combined with the mechanical drive of the vehicle itself. This transformer for low voltage was widely implemented according to the “Kiepach-Weiland System”. Kiepach also patented a maritime compass that indicates north regardless of the presence of iron or magnetic forces.
No car would be the same today if it weren’t for Josip Belusic, a Croatian inventor from Istria. He designed the first electric speedometer. He displayed his invention at the World’s Fair in Paris in 1889, the same one where the Eiffel Tower was first introduced.
