Hildegard Stücklen

Hildegard Stücklen (3 May 1891, in Berlin, Germany – 15 December 1963, in Germany) was a German-American physicist who dealt with spectroscopy. She worked initially as a lecturer and tutor in Switzerland in the 1930s and later moved to teach at women colleges in Massachusetts and Virginia after emigrating to the United States.

Life and career
Stücklen, the daughter of factory owner Hermann Stücklen, was assistant to Eduard Riecke and earned her doctorate in 1919 at the University of Göttingen with Robert Wichard Pohl with a dissertation on the question of the apparent form of the firmament. Then she went to Zurich, interrupted by a year in Delft (1921). In 1931 she qualified as a lecturer at the University of Zurich, where she was a private tutor. While Stücklen worked at the University of Zurich, she worked with chemist Jeanne Eder and physician Mariette Schaetzel in 1933. In October 1933, Stücklen was threatened to leave Switzerland to return to Germany. Jeanne Eder allowed Stücklen to receive a fellowship from the Rockefeller Fund which allowed her to emigrate to the United States in 1934. In 1934 she emigrated to the United States with the help of the Swiss Association of University Women and a National Research Council Fellowship. Stücklen taught at the Mount Holyoke women's college in South Hadley, Massachusetts until 1939. In 1943, Stücklen then taught physics at the private women's college Sweet Briar in Sweet Briar, Virginia where she retired in 1956. She retired in 1956 but spent four more years as chairman of the Wilson College Physics Faculty in Chambersburg, Pennsylvania. After retiring again in 1960, she returned to Germany, where she died in 1963.

In the US, she collaborated frequently with Hertha Sponer, who had an experimental laboratory at Duke University, not far from Sweet Briar College.
