Selma Freud

Selma Freud is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Selma Freud rather than just read about it. In short: Selma Freud (b., 21 August 1877, Vienna, d. after 1933, probably in Israel) was an Austrian physicist and the founder of the first official Salvation Army corps in Vienna. She received her doctorate in physics from the University of Vienna in 1906 and was widely thought to be the first Austrian woman to do so, although she was in fact the second.

Key takeaways

  • Selma Freud belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Selma Freud to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Selma Freud from memory before moving on to harder problems.

Reference excerpt

Selma Freud (b., 21 August 1877, Vienna, d. after 1933, probably in Israel) was an Austrian physicist and the founder of the first official Salvation Army corps in Vienna. She received her doctorate in physics from the University of Vienna in 1906 and was widely thought to be the first Austrian woman to do so, although she was in fact the second. There is no record of Freud pursuing physics research beyond her dissertation. Instead, having been raised Protestant in a largely Catholic country, Freud trained with the Salvation Army in London in the early 1920s and in 1926 founded the first Austrian chapter of the Heilsarmee (the Army's German name) in Vienna in the face of local opposition there.

Life

Childhood Selma Freud was the daughter of a Viennese manufacturer, Simon Siegmund Freud, who operated a factory at Amerlingstrasse 19, Mariahilf, in Vienna's 6th district and who later owned a house (where Selma may have lived) at Hugo-Wolf-Gasse 1 on a corner of Loquaiplatz. She attended elementary school in Vienna and then an all-girls Lyzeum run by the Vienna Women's Employment Association (Frauenerwerbsverein). She then went to Prague to take the Matura (high school graduation exam), as women at the time were not allowed to take it in Austria.

University and graduate school The University of Vienna had begun admitting women in 1897, and Freud began her studies there in 1901, majoring in physics and minoring in mathematics. Her professors included the renowned physicists Franz Exner and Ludwig Boltzmann. Freud submitted her doctoral dissertation—"On the Influence of Temperature on the Photoelectric Sensitivity of a Negatively Charged Conductor"—in 1905 and passed her oral examinations that November. Professors Exner and Boltzmann approved her dissertation, and she was awarded her doctorate the following 1 February. Although Freud was thought for some time to have been the first woman to receive a doctorate from the University of Vienna, Olga Steindler (1879–1933) had already achieved that in 1903. Freud's fellow physics student and later renowned physicist Lise Meitner also received her doctorate on the same day as Freud. Freud's research on physics after graduation remains unknown, as the curriculum vitae originally attached to her handwritten dissertation was lost and no further records can be found. Austrian physicist Karl Przibram, discussing Meitner, later recalled, "Another physicist, Selma Freud, graduated with [Meitner] and worked in the same room as her on Türkenstraße, but apparently did no more scientific work."

The Heilsarmee (Salvation Army) Freud appears again in the historical record only in the 1920s, when she trained at Salvation Army headquarters in London. Women and men were treated equally in the London office, and Freud trained there as an officer (captain). In 1926, facing opposition from the local population and (Catholic) churches in Vienna, she established the first Heilsarmee outpost in Vienna—a "corps"—and held unofficial meetings. In May 1927, work was begun on the chapter's own building, and Salvation Army Lieutenant Commissioner Bruno Friedrich later presided over its opening, with Captain Lydia Saak the officer-in-charge. Also in 1927, at a meeting of the Vienna Evangelical Alliance, Freud presented a paper outlining her ideas about "the united front of the evangelical Christian communities with respect to the outside world" in which she discussed the Heilsarmee's "behavior towards Pentecostals, Adventists, [and] Bible students, whether they can be brought in later." Thus, was Freud considering a tremendous expansion of the participants in the Evangelical Alliance that would only occur half a century later, simultaneous to the founding of the Free Church in Austria, and then only including the Pentecostals. Freud continued to hold prayer and thanksgiving meetings and in 1928 also created a monthly official organ of the Salvation Army in Austria, "The War Cry" (Kriegsanruf), serving as editor from the first issue (July 1928) until May 1938, when Adolf Kossuth assumed the role. Freud also published several of her own articles in the Kriegsanruf. At the end of a trip report published on 27 September 1933, for example, she wrote. "In the next issue, my friends and comrades, I hope, God willing, to already be reporting on our healing work in the Holy Land." Whether Freud participated in the founding of another corps in Palestine or Jerusalem is not known.

Worked examples

Example 1 — a first encounter with Selma Freud

Start with the simplest possible case. Write down what Selma Freud claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Selma Freud before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Selma Freud ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Selma Freud

In research
Selma Freud appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Selma Freud in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Selma Freud is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1877 births, 1933 deaths, Austrian physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Selma Freud outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
