Eugen Heinrich Josef Nesper (5 July 1879 – 3 May 1961) was a German radio pioneer and high-frequency technician.
[1] Eugen Nesper was born in Meiningen, and studied electrical engineering and economics until 1902 at the Technische Hochschule (technical high-school) in Charlottenburg.
He experimented in wireless telegraphy in 1897 in Potsdam-Babelsberg, under the supervision of Professor Adolf Slaby (1849–1913) and his assistant Georg Graf von Arco (1869–1940).
After three years as an assistant, Nesper received his doctorate at the University of Rostock.
Nesper gained fame with a number of publications on the radio technology, both in scientific journals such as Der Radio-Amateur and Elektrotechnische Zeitschrift, as well as with numerous books of his own, including the standard work Wege zum Detektorlautsprecher (Methods of the Detector-Loudspeaker), which appeared in 1946 and was revised substantially in 1949.
