Rachel Shalon

Rachel Shalon is a engineering 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 Rachel Shalon rather than just read about it. In short: Rachel Shalon (Hebrew: רחל שלון, born Rachel Znamirowska) (March 1904 - Sept. 1988) was the first woman engineer in Israel (and formerly in the British Mandate of Palestine) and a professor of structural engineering. Shalon was first of all Technion graduates, male and female, to reach the rank of full professor.

Reference excerpt

Rachel Shalon (Hebrew: רחל שלון, born Rachel Znamirowska) (March 1904 - Sept. 1988) was the first woman engineer in Israel (and formerly in the British Mandate of Palestine) and a professor of structural engineering. Shalon was first of all Technion graduates, male and female, to reach the rank of full professor.

Early life and education Rachel Znamirowska was born in Kalush, Poland on the eve of Passover 1904 to Gittel and Hanoch Znamirowski, a Hassidic family. Her father was a lumber merchant, and she grew up in Kalush. Her father taught her, and her siblings the importance of independence. As a young girl, she was determined to learn Hebrew even though her father forbade it. Aged fifteen, she decided that she wanted to attend a Jewish school in Warsaw, due to the antisemitism in the private school she attended. Her parents did not want her to leave home, so she went on a hunger strike and was eventually allowed to move to her aunt's home in Warsaw, where she graduated from high school with honors in mathematics. She then studied chemical engineering at Warsaw's polytechnic institute, but due to antisemitism she experienced there, she intended to continue her studies in the Czech Republic instead. Before she moved colleges, in 1925 she joined a group of Jewish students on a tour of Eretz Yisrael, at the time Mandatory Palestine, where the Hebrew University had recently opened. She decided to make Aliyah and stay there, to her parents' chagrin, and they told her that they would stop supporting her financially. She studied structural engineering in the Technion, and worked in the laboratories of the Nesher cement factory during her studies, graduating in 1930.

Career From 1931 and until her retirement in 1973 Shalon was a member of the academic staff at the Technion, in the faculty for civil engineering. Over the years she was appointed as vice president for Research, Vice President for Academic Affairs, and Dean of the School for Graduate Studies. In 1956 Shalon was made a professor and in 1965, she was appointed Rector of the Technion. At this time only around 8% engineering students at the Technion were women and Shalon said, "I have closer and more intimate ties with the female students; they also turn to me with personal problems, as a woman speaks to another". Alongside her academic work she was a member of the Hagana organization and, upon the establishment of the State of Israel, served as an officer in the Israel Defense Forces with the rank of a Major. Shortly after the establishment of the State of Israel, Shalon was appointed as chairperson of the professional committee for building within the Scientific Council at the Prime Minister's Office. She remained in this position until 1956, quitting in protest of insufficient funds aimed at research of construction. At this time Shalon established the Building Research Station, which she headed for 20 years. Shalon was a member of the Council for Higher Education in Israel. In 1954 she established the local chapter of Soroptimist organization, later becoming president of its European federation. In 1959 Shalon was elected as president of the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) and in 1962 as member of the executive in the International Council for Construction Research. Together with her husband, engineer Uriel Shalon, she established a fund for construction of student dorms in the city. In 1960, Shalon was interviewed by Ada Cohen for Maariv, a very popular commercial newspaper in Israel at the time, in an article titled “Mrs. Professor”.

Awards and honours Honorary citizen of Haifa In 1980, Shalon was among the torch lighters in the official Independence Day celebrations In 1988, she received an honorary doctorate from the Technion

Personal life In 1930 Rachel Znamirowska married Uriel Shalon, also an engineer, and became known as Rachel Shalon. Professor Rachel Shalon's niece Marjem Chatterton (née Znamirowska/Znamerovschi) also studied engineering at the Technicon in 1934-1939 and became a leading structural engineer in both Israel and Zimbabwe.

Images Four images taken in Professor Shalon's office in 1963 by Boris Carmi are held by the National Library of Israel. They show the piece of concrete and vase of flowers on her desk mentioned in the 1960 Maariv article.

Worked examples

Example 1 — a first encounter with Rachel Shalon

Start with the simplest possible case. Write down what Rachel Shalon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Rachel Shalon 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 Rachel Shalon 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 Rachel Shalon

In research: Rachel Shalon appears in engineering 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 Rachel Shalon 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: Rachel Shalon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1904 births, 1988 deaths, 20th-century Israeli engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Rachel Shalon 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.
