ON THE BOOKSHELF:
From Immigrant to Inventor
by Michael Pupin / Paperback: 436 pages / Kessinger Publishing (March 1, 2003)
A Pulitzer Prize winning book, Pupin's main objective in this narrative was to describe the rise of idealism in American science and particularly in physical sciences and the related industries. He was a witness to this gradual development and everything he describes was an attempt to qualify as a witness whose testimony has competence and weight.

Inventions and Patents
Michael Pupin has, U.S..  patented 24 inventions. The first one in 1894. and the last in 1923. Inventions are in the fields of telephony, telegraphy and radio. He became world famous inventing the process of pupinisation, which made very long distance transmission of text and speech possible. So, this process was given his name.

Pupin the Scientist
Michael Idvorsky Pupin was American physicist who devised 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. He invented the tuned oscillating circuit, which made possible the simultaneous transmission of several messages. POP-UP ADS.
