Maximilian Julius Otto Strutt (born October 3, 1903 in Surakarta , Indonesia , † July 15, 1992 in Rüschlikon , ZH) was a Dutch electrical engineer .

biography

Max Strutt started middle school in Yogyakarta, Indonesia, and graduated in Augsburg, Germany after moving to Europe. Strutt then studied electrical engineering at the Technical University of Munich from 1921 to 1923, then followed by the Technical University of Delft , the Netherlands . He then became an assistant to Prof. Fokker in 1926 and completed his doctorate in 1927 at the age of 24 with the dissertation (translated from Flemish) Skin effect and temperature distribution in electrical conductors .

Even before the formal award of the title of Dr. sc. techn. In 1927 he joined the research laboratories of Philips in Eindhoven, NL. An extremely fruitful creative period followed with important fundamental knowledge and inventions. His work on Lamésche and Mathieu functions in physics and technology, which appeared in 1932, serves as a good example. The work was reprinted 13 times up to the last edition in 1967. For around 20 years, including during World War II , he worked at Philips Research on topics such as electroacoustics, electron tubes , losses in dielectrics , high frequency circuits, antenna technology and high voltage lines. In addition to publications in professional journals, he has published several books and authored over 50 internal research reports . In contrast to many of his colleagues, he continued to write these internal reports in German, while most of his colleagues switched to English from around 1935 due to Germany's political role. A number of patents with Maximilian Strutt as the inventor can be found on Espacenet of the European Patent Office.

In 1948, the Swiss Federal Institute of Technology in Zurich appointed a full professor for theoretical electrical engineering. From 1957 he became a professor for higher electrical engineering. During this time, he taught many years of electrical engineering students, supervised 40 doctoral students (including the later ETH professors Werner Bächtold, George Guekos, Walter Guggenbühl, Hans Melchior) and suggested personalities in electrical engineering for awarding an honorary doctorate from the ETH (including Gustav Guanella ). After the invention of the transistor, he also devoted himself to semiconductor electronics and wrote corresponding specialist books. Some of the books he published served as teaching aids, such as lecture texts on theoretical electrical engineering (1951), electron tubes (1957), field theory (1964), lighting technology (1964), solid state technology (1965 + 1970), although his books published in English by far found widespread use in libraries worldwide. Several works were available in over 200 libraries.

He retired in 1974.
