Biography

Clara von Simson, the daughter of Georg von Simson, a Berlin banker, and a great-granddaughter of the temporary president of the Frankfurt National Assembly in 1848/49, Eduard von Simson. She attended a private schooling, followed by a Höhere Töchterschule and an English college. She studied mathematics and physics briefly in Heidelberg and physics and chemistry at the Friedrich Wilhelm University in Berlin from 1918 to 1923. In 1923, she received her doctorate in the field of experimental physics on the subject of X-ray structure investigations. She completed her dissertation Röntgen-Untersuchung an Amalgamen under supervisision of Franz Simon, Max von Laue, and Max Bodenstein. From 1927 to 1930, she was an assistant at the Physical Chemistry Institute in Berlin. In April 1931, she became temporary lecturer in mathematics and physics at the Pedagogical Academy Dortmund, but stopped at her own request and became a private scholar. Due to the National Socialists, she was not allowed to attend the Physical Colloquium starting in 1935 and she started to live on translations. She was supported by her promoter Max von Laue, to whose circle of friends she belonged. From 1939 to 1945, she worked for the Patent Attorney Office Wüsthoff in Berlin and supported politically and racially persecuted in her free time.

Politically unencumbered, she was again able to work at the Technical University of Berlin directly in 1945, became a senior engineer in thermodynamics in chemistry at the Chair of Inorganic Chemistry and habilitated there as the first woman in physics (thermal conductivity of ammonium chloride) in 1951. In 1949/50, she was visited her former doctoral supervisor Franz Simon for a research stay in Oxford. Franz Simon had emigrated to Oxford. In 1952, she left the TU Berlin and became director of the Lette Association which was devoted to the education of women. She remained the director until 1963.

Politics

Since 1949, von Simson was a member of the FDP (or originally LDPD). As a FDP member, she was part of the Berlin House of Representatives from 1963 to 1971. In parliament, she was a member of the committees for science and art and education. From 1958 to 1977 she was a member of the board of trustees of the Friedrich Naumann Foundation. The last nine years of this time, she was the chairwoman. Together with Agnes von Zahn-Harnack, Gertrud Bäumer, Elly Heuss-Knapp, and Marie-Elisabeth Lüders, she belonged to a circle of friends around Freda Wuesthoff, who protested with her Arbeitsprogramm für den dauernden Frieden against nuclear weapons.

She found her last resting place on the Friedhof III der Jerusalems- und Neuen Kirchengemeinde (de). The honorary grave of the city of Berlin is located in the abbot 4/3. The estate of Clara von Simson is in the archive of Liberalism of the Friedrich Naumann Foundation in Gummersbach.

Honors

Clara von Simson was appointed honorary senator of the TU Berlin in 1966 and she was appointed city elder of Berlin in 1973. In 1967, she received the Cross of Merit 1st class of the Federal Republic of Germany. In 1978, she received the Great Federal Cross of Merit.

The Clara von Simson Prize is awarded by the TU Berlin for the best theses of female students especially in natural and technical sciences. Furthermore, a street in Berlin-Charlottenburg in the Spreebogen is named after her. Furthermore, an association to promote the Lette Association is named after her.
