Spyro Kyropoulos
Spyro Kyropoulos ( Greek Σπυρίδων Κυρόπουλος ), occasionally Spiro ( Σπύρος ; * 1887; † 1967 in the USA ), was a Greco-German physicist. The Nacken -Kyropoulus method for growing crystals is named after him. Later he also worked in the field of lubricants .
Life
Although the family name suggests a Peloponnese origin, the biography of his son Peter Kyropoulos, who like his father worked at the California Institute of Technology in the 1950s , indicates that the family comes from Macedonia .
Spyro Kyropoulos received his doctorate in Leipzig in 1911 and completed his habilitation in Göttingen in 1931, the same year the venia legendi for physical technology was awarded. In 1936 Kyropoulos emigrated with his family to the USA because of strong differences to the National Socialist political system.
On August 17, SA men gathered in front of the house of the Jewish family Graefenberg . They insulted Ms. Kyropoulos, who lived in the neighboring house. When they then entered her house, she stood up against them with a club and said, "I will beat you all down, you pig people, and if there is no man to protect the Jews, then I will sacrifice myself." . Although the media downplayed the case as hysteria, her husband's venia legendi was withdrawn on February 11, 1936 due to the Reichshabilitation regulations. It was the only documented case of a protest against the deportations of Jews in Göttingen.
Spyro Kyropoulos and his wife left Germany. Then Kyropoulos was a Research Fellow at the California Institute of Technology from 1937 to 1949, and then Research Associate from 1949. In 1940 he became a Fellow of the American Physical Society .
