Mihajlo (Michael) Idvorski Pupin

I found a mistake as a date of birth and due to misunderstanding of documents showing his born date and baptising date in serbian church papers and in both cases shown in two dofferent ways because of different callendars, gregorian and yulian. Date supposed to be 9. October.

Mihajlo Idvorski Pupin, Ph.D, LL.D. (Serbian Cyrillic: Михајло Идворски Пупин), also known as Michael I. Pupin, was a Serbian-American physicist and physical chemist. Pupin is best known for his numerous patents, including a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire (known as "pupinization"). Pupin was a founding member of National Advisory Committee for Aeronautics (NACA) on March 3, 1915, which later became NASA.
