Named after him, and patented by him Pupin coil from 1894 enabled the calling and sending messages over long distances.

Training

Pupin emigrated with 19 from Austria - Hungary to the United States. He worked for several years in lower occupations, for example in the biscuit factory in the Cortlandt Street in Manhattan. In 1879 he began to study at Columbia College, where he had a reputation as an excellent student and athlete. In 1883 he graduated with honors, and was also an American citizen. He gained his doctorate in Berlin under Hermann von Helmholtz. In 1889 he returned to New York and became a professor of mathematical physics at the newly established Institute of Electrical Engineering at Columbia University. He searched among others via the carrier wave rectification and power flow analysis.

Scientific Work

In 1894 he patented what is now known as Pupin coil technology. American Telephone and Telegraph (AT & T) bought the patent and making him a rich man. Pupin's work was based on the seven years previously was basic work of Oliver Heaviside, an English physicist and mathematician.

Pupin was one of the first to Roentgen's experiments in the United States traced. In 1896 he invented the method, with a fluorescent substance coated sheet of paper next to place the photographic plate, which reduced the exposure time of more than an hour to a few seconds. He also led the first American study by the medical utility of X-rays. Shortly thereafter, in April 1896, he fell ill with pneumonia and nearly died of it. His wife, who nursed him, put to himself, and died. Research on X-rays, he gave up after his recovery.

In 1901 he became professor emeritus in 1931. He lived in New York City and Norfolk, Connecticut, where he was a country house in the Serbian style had built himself. For his work in electrical engineering in 1920, he received the Edison Medal.

The lunar crater Pupin and the building of the physics department at Columbia University in New York, the Pupin Physics Laboratories also known as Pupin Hall, are named after him.

Policy

In 1911 he was appointed consul of the Kingdom of Serbia in the United States. In his address to Congress, January 8, 1918 President Woodrow Wilson urged, inspired by conversations with Pupin, the restoration of Serbia and Montenegro and autonomy for the peoples of Austria -Hungary.

He also wrote The New Reformation (1927) and Romance of the Machine ( 1930) as well as various technical articles. Subject of many of his writings was his view that science support the belief in God and deepen. Pupin was active in the Serbian immigrant community in the U.S. and was the founder and first president of the Serbian National Defense Council of America ( Serbian National Defense Council of America ). In 1918 he published a book on Serbian sacral monuments under the title of Serbian Orthodox Church ( Serbian Orthodox Church ).

Patents

Pupin has published over 70 technical articles in relevant journals and held more than 30 patents.

Private life

He had four brothers and five sisters. After his emigration to the U.S., he changed his name to Michael Pupin Idvorsky and married in 1888 the American Sarah Catharine Jackson from New York with whom he had a daughter.
