German professor of physics.
Pringsheim came from the extremely wealthy German-Jewish family Pringsheim from Silesia and was the son of the mathematician Alfred Pringsheim (1850-1941) and his wife Hedwig Pringsheim (1855-1942), the daughter of the women's rights activist Hedwig Dohm. Pringsheim's sister, Katia Mann, was the wife of the writer Thomas Mann. Peter married to Emilia "Emmeke" Theodora Clément in 1923.
Like his father, he embarked on an academic career as a physicist. After graduating from high school in 1899 at the Wilhelms-Gymnasium Munich, he studied from 1900 to 1906 at the University of Munich and completed his studies with a doctoral thesis in the physics of gas discharges under Wilhelm Conrad Röntgen. After completing his studies, Peter Pringsheim worked as a post-doctoral student with Eduard Riecke in Göttingen and JJ Thomson in Cambridge, England. Pringsheim received the suggestion from Thomson to deal with the photoelectric behavior of alkali metals. When Pringsheim joined the Physics Institute at the University of Berlin under director Heinrich Rubens in 1908, he met Robert Wichard Pohl there, who was already working in this field. The result of this collaboration was the specialist book Die Photoelectric Phenomena in 1914.
The First World War broke out while attending a conference held in Australia by the British Association for the Advancement of Science, which is why Pringsheim was interned at Trial Bay Gaol in Australia as a German. He spent the entire war in an internment camp and was not released until 1919. During the internment period, Pringsheim was able to read specialist physical literature. He dealt with the field of fluorescence and phosphorescence and, when he returned to Berlin in 1919, brought with him an almost finished book manuscript based solely on a study of literature, which was then published in 1921 under the title Fluorescence and Phosphorescence in the Light of Newer Atomic Theory. His colleague Pohl has now completed his habilitation and in 1920 he was a professor at the University of Göttingen, as did another colleague at the Berlin institute, James Franck. This was to play a special role in Pringsheim's life.
Since Pohl was now in Göttingen, Pringsheim turned exclusively to his new field of work fluorescence and phosphorescence, which he worked on for life. As a result of his research and lectures, he became a außerordentlicher Professor in 1925 and persönlicher ordentlicher Professor der Physik at the University of Berlin in 1930.
Although baptized as a Protestant, he, like the other members of his family, was persecuted by the National Socialists (Nazis) because of his Jewish descent. In 1933, Peter Pringsheim was initially "on leave" and then "retired" on the basis of the law to restore the civil service, which was tantamount to a professional ban.
Presumably with the help of his Belgian wife, Pringsheim succeeded in getting Auguste Piccard, who was a physics professor at the Belgian Université Libre in Brussels, to accept him into his institute. Here Pringsheim initially worked as a third-party researcher from 1933 to 1937, and from 1937 as Professeur agréé.
After the German troops marched into Belgium, Pringsheim was arrested on the street on May 10, 1940 and taken to the French concentration camp Gurs. His wife Emilia had no information about her husband's whereabouts until the end of the war. With the help of high-ranking political figures, Pringsheim's brother-in-law Thomas Mann was able to get Pringsheim released from the camp on December 6, 1940. However, proof of employment at an American university was required for entry into the USA. His former colleague James Franck, now a professor at the University of Chicago, stood up for him, and eventually managed to find a third-party funded one-year job at the University of California. 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 position in Chicago, because not all positions were filled due to the war. Pringsheim accepted this offer and worked at the Franck Institute in Chicago until 1944. In 1943 he became a Fellow of the American Physical Society. Because of the now foreseeable end of the war and the imminent departure in case of return of the jobholder, Pringsheim took a job as Director of Scientific Research at Ray Control Laboratories in Pasadena, California on 1 September 1944. However, he was fired on July 9, 1946, as the company dissolved its research department, whereupon Franck gave him a job at the state research institute Argonne National Laboratory near Chicago. He worked there from 1947 to 1954 and only left when he was 73 years old.
Pringsheim returned to Belgium and lived there with his wife in Antwerp. In 1961 he received an honorary doctorate from the University of Giessen.
