Peter Pringsheim ( March 19, 1881 - 20 November 1963 in Antwerp, Belgium) was a German professor of physics.
Pringsheim came from the extremely wealthy Silesian merchant family of Jewish descent Pringsheim and was the son of the mathematician Prof. Dr. Alfred Pringsheim (1850-1941) and his wife Hedwig Pringsheim (1855-1942), the daughter of the woman's rights activist Hedwig Dohm. Pringsheims sister Katia Mann, wife of writer Thomas Mann. He was married with Emmeke (also Emilia) Clément since 1923.
Like his father, he suggested as a physicist, an academic career. After graduating from high school in 1899 at the Wilhelmsgymnasium He studied from 1900 to 1906 at the University of Munich and graduated with a PhD in physics of gas discharges from Wilhelm Conrad Röntgen. After studying Peter Pringsheim worked as a post-doctoral fellow with Eduard Riecke in Göttingen and JJ Thomson in Cambridge, England. Thomson Pringsheim was given the suggestion to deal with the photoelectric behavior of the alkali metals. As Pringsheim 1908 entered the Physics Institute of the University of Berlin under director Heinrich Rubens, he met on Robert Pohl, who has worked in this field. Result of this collaboration was the textbook The photoelectric phenomena of the 1914th
During the visit, one held in Australia Conference of the British Science Association of the First World War broke out, which is why Pringsheim was interned in Australia as German. He had to spend the entire war in an internment camp, was further detained after the war and released in 1919. In the period of internment it was Pringsheim possible to read physical literature. He dealt with the branch fluorescence and phosphorescence, and brought, when he returned in 1919 to Berlin, an almost ready-BASED solely on literature study book manuscript, which was then published in 1921 under the title fluorescence and phosphorescence in the light of recent atomic theory. His colleague Pohl says he still and 1920 Professor at the University of Göttingen, as well as another colleague at the Berlin Institute, James Franck. This was to play a special role in the life Pringsheims. Then Pohl was now in Göttingen, Pringsheim turned himself exclusively to his new job field fluorescence and phosphorescence, which he edited for life. As a result of his research and teaching in 1925 he planned, known as associate professor and 1930 personal associate professor of physics at the University of Berlin.
Although evangelical baptized, he was like the other members of his family persecuted by the Nazis because of his Jewish ancestry. Peter Pringsheim in 1933 initially "on leave" on the basis of the Law for the Restoration of the Professional Civil Service, and then "retired", which was equivalent to a prohibition.
Probably with the help of his Belgian wife succeeded Pringsheim that Auguste Piccard, a physics professor at the Université Libre de Bruxelles, was admitted him to his institute. Here Pringsheim initially worked from 1933 to 1937 as third-party funds researchers in 1937 agré as Professeur. In Brussels Pringsheim had a young employee E. Hirschlaff, who had followed him from Berlin and also worked in the USA for Pringsheim, and later a professor at the University of London was.
After the invasion of German troops in Belgium Pringsheim was arrested on 10 May 1940 on the road and finally to the French concentration camp at Gurs. His wife Emilia had to end of war no information about the whereabouts of her husband. With the help of high-ranking personalities from politics could Pringsheims brother Thomas Mann achieve it, that Pringsheim was released from the camp on December 6, 1940. But the proof of a job at an American university was required for entry into the United States. His former colleague James Franck, now a professor at the University of Chicago, stood up for him, and finally succeeded at the University of California to find a third-party funded and limited to one year of employment. One half of his salary was paid by the Emergency Committee in Aid of Displaced Foreign Scholars, the other half by Thomas Mann personally.
Before the end of the year Franck Pringsheim offered a job in Chicago, as a result of the war, not all positions were filled. Pringsheim accepted this offer and worked until 1944 in Franck's Institute in Chicago. Because of the now foreseeable end of the war and the impending retirement in case of return of the jobholder, Pringsheim took on 1 September 1944, a position in the industry. However, he was released on 9 July 1946, as the company broke up their research department, prompting him Franck mediated a job at the State Research Institute Argonne National Laboratory, near Chicago. He worked there from 1947 to 1954 and retired from only 73 years old.
Pringsheim returned to Belgium, where he lived with his wife in Antwerp. In 1961 he received an honorary doctorate from the University of Giessen.
