Mihajlo Idvorski Pupin (Template:Lang-sr-Cyrl, Template:IPA; October 4, 1858<ref name="birth year">Although Pupin's birth year is sometimes given as 1854 (and Serbia and Montenegro issued a postage stamp in 2004 to commemorate the 150th anniversary of his birth), peer-reviewed sources list his birth year as 1858. See:

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 3 March 1915, which later became NASA,<ref>Template:Cite web</ref> and he participated in the founding of American Mathematical Society and American Physical Society.

In 1924, he won a Pulitzer Prize for his autobiography. Pupin was elected president or vice-president of the highest scientific and technical institutions, such as the American Institute of Electrical Engineers, the New York Academy of Sciences, the Radio Institute of America, and the American Association for the Advancement of Science. He was also an honorary consul of Serbia in the United States from 1912 to 1920 and played a role in determining the borders of newly formed Kingdom of Serbs, Croats and Slovenes.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>

Early life and education

Pupin's birthplace

Mihajlo Pupin was an ethnic Serb,<ref>Template:Cite book</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref> born on 4 October (22 September, O.S.) in the village of Idvor (in the modern-day municipality of Kovačica, Serbia) in the region of Banat, in the Military Frontier of the Austrian Empire, 1858. He always remembered the words of his mother and cited her in his autobiography, From Immigrant to Inventor (1923):<ref name=":2">Template:Cite book</ref>

Pupin went to elementary school in his birthplace, to Serbian Orthodox school, and later to German elementary school in Perlez. He enrolled in high school in Pančevo, and later in the Real Gymnasium. He was one of the best students there; a local archpriest saw his enormous potential and talent, and influenced the authorities to give Pupin a scholarship.

Because of his activity in the "Serbian Youth" movement, which at that time had many problems with Austro-Hungarian police authorities, Pupin had to leave Pančevo. In 1872, he went to Prague, where he continued the sixth and first half of the seventh year. After his father died in March 1874, the twenty-year-old Pupin decided to cancel his education in Prague due to financial problems and to move to the United States.

Studies in America and Ph.D.

Pupin c. 1935

For the next five years in the United States, Pupin worked as a manual laborer (most notably at the biscuit factory on Cortlandt Street in Manhattan) while he learned English, Greek and Latin. He also gave private lectures. After three years of various courses, in the autumn of 1879 he successfully finished his tests and entered Columbia College, where he became known as an exceptional athlete and scholar. A friend of Pupin's predicted that his physique would make him a splendid oarsman, and that Columbia would do anything for a good oarsman. A popular student, he was elected president of his class in his Junior year. He graduated with honors in 1883 and became an American citizen at the same time.

After Pupin completed his studies, with emphasis in the fields of physics and mathematics, he returned to Europe, initially the United Kingdom (1883–1885), where he continued his schooling supervised by John Tyndall at the University of Cambridge. He obtained his Ph.D. at the University of Berlin under Hermann von Helmholtz with a dissertation titled "Osmotic Pressure and its Relation to Free Energy".<ref name=":1">Template:Cite web</ref>

Professor at Columbia University

In 1889 Pupin returned to Columbia University, where he was offered a position as "Teacher of Mathematical Physics in the Department of Electrical Engineering".<ref>Template:Cite web</ref> Shortly afterwards he was appointed associate professor, and in 1901 professor of electromechanics.<ref name=":1" /> Pupin's research pioneered carrier wave detection and current analysis.<ref name="ieeeghn.org">Template:Cite web</ref>

First meeting of the NACA in 1915 (Pupin seated first from right)

He was an early investigator into X-ray imaging, but his claim to have made the first X-ray image in the United States is incorrect.<ref>Nicolaas A. Rupke, Eminent Lives in Twentieth-Century Science and Religion, p. 300, Peter Lang, 2009 Template:ISBN.</ref> He learned of Röntgen's discovery of unknown rays passing through wood, paper, insulators, and thin metals leaving traces on a photographic plate, and attempted this himself. Using a vacuum tube, which he had previously used to study the passage of electricity through rarefied gases, he made successful images on 2 January 1896. Edison provided Pupin with a calcium tungstate fluoroscopic screen which, when placed in front of the film, shortened the exposure time by twenty times, from one hour to a few minutes. Based on the results of experiments, Pupin concluded that the impact of primary X-rays generated secondary X-rays. With his work in the field of X-rays, Pupin gave a lecture at the New York Academy of Sciences. He was the first person to use a fluorescent screen to enhance X-rays for medical purposes. A New York surgeon, Dr. Bull, sent Pupin a patient to obtain an X-ray image of his left hand prior to an operation to remove lead shot from a shotgun injury. The first attempt at imaging failed because the patient, a well-known lawyer, was "too weak and nervous to be stood still nearly an hour" which is the time it took to get an X-ray photo at the time. In another attempt, the Edison fluorescent screen was placed on a photographic plate and the patient's hand on the screen. X-rays passed through the patients hand and caused the screen to fluoresce, which then exposed the photographic plate. A fairly good image was obtained with an exposure of only a few seconds and showed the shot as if "drawn with pen and ink." Dr. Bull was able to take out all of the lead balls in a very short time.<ref>William R. Hendee, E. Russell Ritenour, Medical Imaging Physics, p. 227, John Wiley & Sons, 2003 Template:ISBN.</ref><ref>Pupin, pp. 307–308</ref>

Pupin coils

Pupin's 1899 patent for loading coils, archaically called "Pupin coils", followed closely on the pioneering work of the English polymath Oliver Heaviside, which predates Pupin's patent by some seven years. The importance of the patent was made clear when the American rights to it were acquired by American Telephone & Telegraph (AT&T), making him wealthy. Although AT&T bought Pupin's patent, they made little use of it, as they already had their own development in hand led by George Campbell and had up to this point been challenging Pupin with Campbell's own patent. AT&T were afraid they would lose control of an invention which was immensely valuable due to its ability to greatly extend the range of long-distance telephones and especially submarine ones.

World War I research

When the United States joined the First World War in 1917, Pupin was working at Columbia University, organizing a research group for submarine detection techniques.<ref>Template:Cite web</ref> Together with his colleagues, professors Wils and Morcroft, he performed numerous experiments with the aim of discovering submarines at Key West and New London. He also conducted research in the field of establishing telecommunications between places. During the war, Pupin was a member of the state council for research and state advisory board for aeronautics. For his work he received acclamation from President Warren G. Harding, which was published on page 386 of his autobiography.<ref>Template:Cite webTemplate:Cbignore</ref>

Yugoslavia borders

Pupin in 1916

By World War I, Pupin was as well-known for Serbian nationalism as science. He wrote that the assassination of Franz Ferdinand in June 1914 "was ... prepared in Vienna" when Austro-Hungarian rule in Bosnia and Herzegovina began in 1878. Pan-Serb ideology was, Pupin said, "a natural heritage of every true Serb".<ref name="pupin19140713">Template:Cite magazine</ref> As a politically influential figure in America, Pupin participated in the final decisions of the Paris peace conference after the war, when the borders of the future kingdom (of Serbs, Croats and Slovenians) were drawn. Pupin stayed in Paris for two months during the peace talk (April–May 1919) on the insistence of the government.<ref name="doiserbia.nb.rs">Template:Cite journal</ref>

According to the London agreement from 1915. it was planned that Italy should get Dalmatia. After the secret London agreement France, England and Russia asked from Serbia some territorial concessions to Romania and Bulgaria. Romania should have gotten Banat and Bulgaria should have gotten a part of Macedonia all the way to Skoplje.<ref name="doiserbia.nb.rs"/>

In a difficult situation during the negotiations on the borders of Yugoslavia, Pupin personally wrote a memorandum on 19 March 1919 to American president Woodrow Wilson, who, based on the data received from Pupin about the historical and ethnic characteristics of the border areas of Dalmatia, Slovenia, Istria, Banat, Međimurje, Baranja and Macedonia, stated that he did not recognize the London agreement signed between the allies and Italy.Template:Citation needed

Mihajlo Pupin foundation

National Home Mihajlo I. Pupin, Pupin's Foundation in his hometown of Idvor (Vojvodina, Serbia). Today is the part of the Memorial Complex in Idvor, which is dedicated to the life and work of Mihajlo Pupin and protected as a cultural monument of exceptional importance.<ref>Template:Cite web</ref>

In 1914, Pupin formed "Fund Olimpijada Aleksić-Pupin" within the Serbian Academy of Sciences and Arts<ref>Template:Cite web</ref> to commemorate his mother Olimpijada for all the support she gave him through life. Fund assets were used for helping schools in old Serbia and Macedonia, and scholarships were awarded every year on the Saint Sava day. One street in Ohrid was named after Mihajlo Pupin in 1930 to honour his efforts. He also established a separate "Mihajlo Pupin fund" which he funded from his own property in the Kingdom of Yugoslavia, which he later gave to "Privrednik" for schooling of young people and for prizes in "exceptional achievements in agriculture", as well as for Idvor for giving prizes to pupils and to help the church district.<ref name="glas-javnosti.rs">Template:Cite web</ref>

Thanks to Pupin's donations, the library in Idvor got a reading room, schooling of young people for agriculture sciences was founded, as well as the electrification and waterplant in Idvor.<ref>Template:Cite web</ref> Pupin also donated over 500 publications to Belgrade University Library.<ref>Template:Cite web</ref> His gifts included scientific books and subscriptions in preparation of the opening of the new building in 1926, and continued with numerous volumes from his private collection in 1932 and 1933.<ref>Template:Cite web</ref> Pupin established a foundation in the National Museum of Serbia in Belgrade. The funds of the foundation were used to purchase works of Serbian artists (including Uroš Predić, Paja Jovanović, Konstantin Danil, among others) for the museum, and for the printing of certain publications.<ref>Template:Cite web</ref> Pupin invested a million dollars in the funds of the foundation.<ref name="glas-javnosti.rs"/>

In 1909,<ref>Template:Cite web</ref> he established one of the oldest Serbian emigrant organizations in the United States called "Union of Serbs – Sloga." The organization had a mission to gather Serbs in immigration and offer help, as well as keeping ethnic and cultural values. This organization later merged with three other immigrant societies.<ref>Template:Cite web</ref>

Other emigrant organizations in to one large Serbian national foundation, and Pupin was one of its founders and a longtime president (1909–1926).

He also organized "Kolo srpskih sestara" (English: Circle of Serbian sisters) who gathered help for the Serbian Red Cross, and he also helped the gathering of volunteers to travel to Serbia during the First World War with the help of the Serbian patriotic organization called the "Serbian National Defense Council" which he founded and led. Later, at the start of the Second World War this organization was rehabilitated by Jovan Dučić and worked with the same goal. Pupin guaranteed the delivery of food supplies to Serbia with his own resources, and he also was the head of the committee that provided help to the victims of war. He also founded the Serbian society for helping children which provided medicine, clothes and shelter for war orphans.<ref>Template:Cite web</ref>

Pupin Hall

Pupin Physics Laboratories at Columbia University

Columbia University's Physical Laboratories building, built in 1927, is named Pupin Hall in his honor. It houses the physics and astronomy departments of the university. During Pupin's tenure, Harold C. Urey, in his work with the hydrogen isotope deuterium demonstrated the existence of heavy water, the first major scientific breakthrough in the newly founded laboratories (1931). In 1934 Urey was awarded the Nobel Prize in Chemistry for the work he performed in Pupin Hall related to his discovery of "heavy hydrogen".<ref name="Urey Nobel Prize Motivation">Template:Cite web</ref>
