Was Kroatien für die Welt getan, entdeckt, etc. hat

Marcel Kiepach (February 12, 1884 - August 12, 1915) was a Croatian inventor. The works and inventions of this child prodigy belong to the areas of electronics, magnetism, acoustics, transmission of sound signals, and transformers.
Marcel was born in Križevci as a descendant of the noble family Kiepach, which came to Križevci in the early 19th century and became influential in the town. He studied economics in Berlin and electrical engineering in Charlottenburg.
In Berlin on March 16, 1910, as a boy of sixteen, Marcel patented a maritime compass that indicates north regardless of the presence of iron or magnetic forces. He patented an improved version in London on December 20, 1911. This second version was a remote maritime compass device, consisting of ampermeters as the indicating instruments located in different parts of the ship, resistant to magnetic forces or magnetic masses in their vicinity.
In France, he patented a dynamo for vehicle lighting. It was an electric generator combined with the mechanical drive of the vehicle itself. His "small transformer" for low voltage was widely implemented according to the "Kiepach-Weiland System". He also patented a power switch. He was active in various other areas of mechanics and electronics. He held correspondence with famous world scientists and inventors.
When World War I broke out, Kiepach volunteered. He died at the Russian front when he was 21. His remains were brought to Križevci in 1917, where they were laid in the family tomb in the Town Cemetery.
His two patents were included in the big exhibition Centuries of Natural Science in Croatia: Theory and Application (June-October 1996, Klovićevi Dvori Gallery). Prof. Vladimir Muljević lectured about his work at the 4th international symposium on new technologies 1993. Today, Križevci have the Marcel Kiepach Innovation Society. The town museum keeps many of his documents and family photographs. In 2004, Križevci held an exhibition about the Kiepach family.
 
Franjo Hanaman (born June 30, 1878 in Drenovci near Županja, Austria-Hungary – died January 23, 1941 in Zagreb, Kingdom of Yugoslavia - Croatia today).
Franjo Hanaman was born in Croatian family as a second child of father Gjuro Hanaman and Emilija Mandušić.[1] He was a Croatian inventor, engineer, and chemist, who gained world recognition for inventing the world's first applied electric light-bulb with a metal filament (tungsten) with his assistant Aleksandar Just, independently of his contemporaries. They were granted the Hungarian Patent #34541 on December 13th, 1904 on Budapest.[2] His invention of tungsten filament was also applied in improoving early diodes and triodes.
 
David Schwarz (* 20. Dezember 1850 in Zalaegerszeg; † 13. Januar 1897 in Wien) war ein kroatisch-ungarischer Erfinder, jüdischer Abstammung.
Schwarz schuf das erste flugfähige starre Luftschiff. Es war auch das erste Luftschiff, dessen Außenhaut vollständig aus Metall bestand. Kurz nach seinem Tod kaufte Ferdinand Graf von Zeppelin das Patent von der Witwe des Verstorbenen.

Gaja Alaga (Lemeš, 1924 - Zagreb, 1988) was a Croatian theoretical physicist who specialised in nuclear physics.
He was born in noble family of Bunjevac Croats in the village of Lemeš (today Svetozar Miletić) in northwestern Bačka in Kingdom of SHS (today in autonomous province Vojvodina, Serbia).
He was an academician of the Croatian Academy of Sciences and Arts since 1968 and a professor at the University of Zagreb, on Prirodoslovno-matematički fakultet. He worked in the Institute "Ruđer Bošković" in Zagreb (the capital city of Croatia), the Niels Bohr Institute in Copenhagen, the University of California, Berkeley, and Ludwig-Maximilians University in Munich.
In 1955, cooperating with Kurt Alder and Ben Roy Mottelson, Alaga discovered the K-selection rules and intensity rules for beta and gamma transitions in deformed atom nuclei. This discovery was key to the development of new nuclei models which confirmed that subatomic particles can distort the shape of the nucleus. These models challenged Aage Niels Bohr, Ben Roy Mottelson and Leo James Rainwater's earlier (1975 Nobel Prize-winning) theory that the nucleus has a perfect spherical shape.
Also in 1955, the journal Physical Review published Alaga's rules for beta and gamma transitions for heavily damaged atomic orbits. Both discoveries are known as Alaga rules, and are now in everyday use among nuclear scientists and in scientific literature.
He was the editor of the scientific magazine Fizika from 1978 until his death in 1998.
He died in Zagreb in 1988.
 
ihr seid schon komisch, einerseits behaart ihr darauf das tesla kroate war, anderseits zählt ihr hier dutzend in australien und usa geborenen und lebenden forscher auf, die nicht mal einen kroatischen pas haben........

Da liegt ein hauch von eifersucht in der luft
