Scientist and inventor. The most significant invention from 1896 is known as “Pupin’s Theory”, which solved the problem of increasing the range of telephone currents by installing inductive coils, named after him “Pupin’s Coils”. Thanks to his inventions in analog telephony, long-distance and international telephone traffic works. During his scientific and experimental work, Pupin gave important conclusions important for the fields of multiple telegraphy, wireless telegraphy and telephony, then radiology, and he has great merits for the development of electrical engineering.<\/p>\n
