Iris Runge (1888-1966) was a German applied mathematician, physicist, and inventor. In her family there were many scientists. Her father was the famous professor in applied mathematics at Göttingen University, Carl Runge (1856-1927). He was a specialist in numerical analysis and one of his results was “Runge-Kutta’s approximation formula”, which is used to solve differential equations numerically. Iris Runge also came to work with numerical analysis later, when she became one of the first “industrial mathematicians.” So she followed in her father’s footsteps, but nevertheless she had a very independent mind through all her life. This independence was very appreciated, both in her family, and at her work.

Iris R. was employed as a mathematical problem-solver at the German corporations, Osram and Telefunken. At first she worked at Osram with research and calculations on incandescent light bulbs. Later she was transferred from Osram to Telefunken, where she worked with radio tubes (electron tubes). Iris R. just loved to calculate and solve problems, and the more complicated problems, the better! This we know from her letters to her family. She was so proficient at her work that, although she was a woman in a man’s world, she became highly respected as a specialist.

Iris Runge was a pioneer, both as an industrial mathematician and as a woman. At her time, it was still hard for women to get a chance to work professionally.

Among the special fields, with which Iris R. worked at Osram and Telefunken, we can mention:

  1. Numerical analysis (mathematics) – before the computers
  2. Applied statistics. She co-authored one of the first textbooks on statistical quality control in mass production. The book was only published in German, so although it was an important and pioneering work, it did not receive the international attention, it ought to have got
  3. Optics
  4. Material science (physics)
  5. Electronics
  6. Besides all this, Iris Runge also made some inventions in physics, electronics, and technology.

An intellectual family in wartimes and before and after

Iris Runge’s family was very culturally interested and they had many English-speaking contacts, because they mastered English. It was really an internationally-oriented family.

But already in the 1930s, there came much political turmoil in Germany because of Hitler and the Nazis. Iris Runge and her family were very conscious and active socially and politically.

During World War II, Iris Runge was forced to stay at Osram and Telefunken. She was not happy with her work anymore, because some of the electronics she worked with could be used in the war. She was not a Nazi. She contemplated emigration to the United States, like her sister and brother-in-law, the great mathematician, Richard Courant (1888-1972), who was a Jew. She had hoped to be able to get an assistantship with the famous Belgian-American historian of science, George Sarton (1884-1956). But this job did not materialize, because he could not get the money for it. So she was forced to stay on at Osram and Telefunken in order to earn a living.

Iris Runge’s brother, Wilhelm Runge (1895-1987), was a pioneer in radar technology, and because radar was very important in the war, he had to work directly under a military contract – and to be a member of the Nazi party. But it is unclear whether he was a confirmed Nazi or not.

We can compare Wilhelm Runge with another German military engineer, the rocket pioneer Wernher von Braun (1912-1977). He was definitely a confirmed Nazi, and he used concentration camp prisoners as slave workers. This has been shown in a TV documentary about Wernher von Braun and the Russian rocket pioneer, Sergei Korolev (1907-1966). After the war, Wernher von Braun was headhunted to the United States, where he became the leader of NASA’s space program. He became very popular in America.

To return to our heroine, Iris Runge, she worked at the crossroads of mathematics, physics, technology, and industry.

After the war, it became difficult for German scientists in military-related jobs to continue their work in Germany in private businesses, because the allied occupation authorities had misgivings about this. Some of the scientists emigrated to the United States (as Wernher von Braun), or to the Soviet Union. Many of those, who chose to remain in Germany, continued their work at the universities. Iris Runge herself also had a university career after the war. She ended as a professor of physics at Humboldt University in Berlin. After the construction of the Berlin Wall in 1961, this university was situated in Eastern Berlin.

Although some of Iris Runge’s work with radio tubes (electron tubes) could be used by the military, the civilian possibilities for applications were even greater. Just think of the radio, television and all other electronics. The electronics of Iris Runge and many others heralded our modern IT-society.

Iris Runge was indeed a pioneer, both professionally, and as a woman scientist in a man’s world.

Williamina Paton Fleming

Thanks to librarian Sam Kome, who passed along this clipping from the Library of Congress archive of an article about Fleming in a newspaper from North Dakota October 18, 1906. Willison, Williams County, N.D.  The headline notes that “Mrs. Fleming has discovered six out of nine new stars.”

Mary Putnam Jacobi

Thank you to Chemist Katherine Van Heuvelen, who pointed out this book:

Headstrong_book_cover

in which Jacobi is the first woman featured.  According to the the book, Jacobi was the “first woman admitted to France’s École du  Médecine.”

An Amazon review by InvisibleMonkeyhouse notes “The pivotal line of this book is delivered by Hertha Ayrton, who was a scientist, an author, a close friend of Marie Curie, and the inventor of a fan that dispersed noxious gas away from soldiers. She is quoted as saying: “Personally I do not agree with sex being brought into science at all. The idea of ‘women and science’ is entirely irrelevant. Either a woman is a good scientist or she is not; in any case she should be given opportunities, and her work should be studied from the scientific, not the sex, point of view.”

Sylvia Miller

Sylvia Miller in 1973 and today

Thank you to Kathy Kobayashi, who forwarded this LA Times article featuring a new book about the women who worked as programmers at JPL by Nathalia Holt, “Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars.”  See the article for a recent interview with Sylvia Miller.

The picture above, from the LA Times Article is captioned “Sylvia Miller, pictured on the left in 1973, was one of the last human computers hired by NASA’s Jet Propulsion Laboratory in 1968. She is now one of the female subjects in a newly released book by Nathalia Holt titled “Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars.” Miller went on to have a 40-year career at JPL and retired in 2008.

Thanks to physicist Karen Daniels, who pointed out this LA Times article about the retirement of U.S. Geological Survey seismologist Lucy Jones.  The article notes that  “She’s retiring from the USGS this month to help officials develop science-based policies related to climate change, tsunamis and other kinds of natural disasters.”

The article discusses her interesting educational history and career, which included an undergraduate degree in Chinese language and literature that led to her becoming the first American scientist to enter China in 1979 to study earthquakes.
