Mihajlo Pupin (Serbian physicist and physical chemist.

Born October 4, 1858
Idvor, Serbia
Died March 12, 1935 (aged 76)

Pupin is best known for his landmark theory of modern electrical filters and 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 president of the Institute of Radio Engineers in 1917 and the American Institute of Electrical Engineers in 1925-1926. Pupin was president of the American Association for the Advancement of Science (AAAS), the New York Academy of Sciences, member of the French Academy of Science, and the Serbian Academy of Science.

In 1920, he received AIEE's Edison Medal For his work in mathematical physics and its application to the electric transmission of intelligence. Columbia University's Pupin Hall, the site of Pupin Physics Laboratories, is a building completed in 1927 and named after him in 1935. A small crater on the Moon was named in his honor. The Mihajlo Pupin Institute, an engineering and technological research insititution, was founded in 1946 in Belgrade.)
