Thank you for time and comment! Tesla was Serbian origin, but from the Lika region of present day Croatia ( at the time of his birth Croatia was part of Austro-Hungarian empire).
First part of the text mentioned just a part of it:
Nikola Tesla (1856–1943) was a brilliant inventor, engineer, and futurist whose groundbreaking contributions laid the foundation for much of modern technology. Born in Smiljan, present-day Croatia, Tesla's insatiable curiosity and extraordinary mind led him to transform the world through his pioneering ideas.
Cheers, Damir
