Michael Pupin: Biography
Born: 4 October 1858
Died: 12 March 1935
Early Life
Michael Idvarsky Pupin was born on 4 October 1858 in the village of Idvor, Banat, now part of Serbia. In his youth, he served as a shepherd. His parents were illiterate, but Pupin was educated at the local school in Idvor. His education progressed in Panchevo and then Prague. In 1874, with the support of his parents but with very little money, he immigrated to New York.
Immigration and Education
Like many poor immigrants, Pupin found that his early experiences in the United States were not easy. He drove mules, worked on farms, and was employed by a cracker factory while he learned English and saved what money he could. Making use of the resources of the Cooper Union in his spare time, he qualified for entrance to Columbia College in 1879 buy passing the entrance exam with high honors. He graduated from Columbia with honors in 1883. He held the John Tyndall fellowship at the university and was president of his class. He became a U.S. citizen the day before graduation. Pupin then spent two years at Cambridge University and continued his education in 1885 at the University of Berlin, studying and conducting research in experimental physics under Hermann Von Helmholtz. He obtained his Ph.D. in Berlin in 1889.
Career at Columbia University
Pupin returned to New York that year to assume the position of teacher of mathematical physics at Columbia; he and Francis Bacon Crocker comprised the faculty of the newly-created department of electrical engineering there. Though the department could make no claims to having the most modern or even sufficient equipment - the laboratory building was known as "the cowshed" - Pupin completed some of his most important work during these early years at Columbia. In 1894, he studied wave propagation in a vibrating string, noting that these waves did not dissipate as rapidly in a string which had weights suspended from it at equal intervals as in an un-weighted string. He applied this finding to long distance telephony, ascertaining the correct spacing of inductance ("loading") coils along telephone lines to remove the barrier of distance from telephone communication. Other important inventions followed. In 1896, he developed a method of rapid x-ray photography, requiring an exposure of only a fraction of a second, rather than that of an hour or more, by placing a fluorescent substance between the photographic plate and the object to be photographed.
He remained with Columbia for life, progressing through the ranks to instructor in 1890, adjunct professor in 1892, professor in 1901 and professor emeritus in 1931. During his long career, he numbered Gano Dunn, Robert Millikan, Edwin Armstrong and Irving Langmuir among his students.
