Jew of the Week: Victor Goldschmidt

Father of Geochemistry

Victor Moritz Goldschmidt (1888-1947) was born in Switzerland, the son of a Jewish-Austrian chemist. The family moved to Norway in 1901 and Goldschmidt went on to study chemistry and geology at what would become the University of Oslo. He got his Ph.D at just 23 years of age, and won a prestigious award for his dissertation. That same year he became an associate professor. In 1929, Goldschmidt became the chair of minerology at the University of Göttingen, but resigned six years later to protest anti-Semitism, returning to Oslo. One of his key discoveries was the mineralogical phase rule, followed by a longer list of the Geochemical Laws of the Distribution of Elements. For this ground-breaking work (and for literally writing the first textbook on geochemistry), he has been called the “Father of Geochemistry”. By 1942, the Nazis had occupied Norway and arrested Goldschmidt. He was taken to the Berg concentration camp where he fell severely ill. He was about to be deported to Auschwitz when a group of colleagues intervened and convinced the Nazis that his scientific knowledge would be useful to them. Goldschmidt was eventually able to escape to Sweden, and from there he was smuggled to England by a British intelligence unit. He assisted the British war effort, was elected to the Royal Society, and continued his work at the Macaulay Institute for Soil Research. He would return to Norway following the war, but died soon after. Goldschmidt received many awards, including being knighted by the king of Norway. The region of Goldschmidtfjella in Norway is named after him, as is the mineral goldschmidtite (KNbO3).

The fact that the universe had a beginning, that it obeys orderly laws that can be expressed precisely with mathematics, and the existence of a remarkable series of “coincidences” that allow the laws of nature to support life – do not tell us much about what kind of God must be behind it all, but they do point toward an intelligent mind that could lie behind such precise and elegant principles.

Jew of the Week: Renata Reisfeld

The Renowned Chemist Who Survived the Holocaust—and Entebbe

Renata Sobel (b. 1930) was born in Chelm, Poland. Orphaned at a young age, she was raised by her grandparents. When the Nazis occupied Poland, the family managed to escape and spent the war years in the harsh conditions of Siberia. Young Renata was unable to receive a formal education. After the war, she was engaged to Eliezer Reisfeld—on the condition that he allow her to pursue an education. As a child, Renata was inspired by a biography of Marie Curie and wished to become a scientist, too. The young family made aliyah to Israel in 1950 and settled in Jerusalem. There, Renata Reisfeld took up studies at the Hebrew University. Despite having no knowledge of Hebrew or English, she was the first to complete the entrance exam into the prestigious chemistry program that had only 23 spots. Reisfeld earned her Ph.D, then went to Oregon State University for post-doctoral work. One of Reisfeld’s main areas of research has been photovoltaic cells, and she played a big role in helping to bring down the cost of solar panels to make renewable solar energy possible on a large scale. She is also an expert on nanotechnology and solid state lasers. By 1975, Reisfeld had become the head of the chemistry department at Hebrew University. The following year, she was invited to speak at a conference in Paris. Her flight from Tel-Aviv made a stop in Athens, where Palestinian and German hijackers took control of the plane and diverted it to Entebbe, Uganda. Because she was one of the few hostages that spoke English, she represented the group of 102 passengers, and spoke with Idi Amin. The dictator took a liking to her, and when she asked him to take the hostages out on a tour of Uganda, Amin agreed! Eventually, the hostages were rescued in a daring raid by Israeli commandoes (which took the life of Yoni Netanyahu, brother of Benjamin Netanyahu). All in all, Reisfeld has published a whopping 532 scientific papers, together with four books, and her work has been cited over 30,000 times, making her among the world’s most prolific and renowned chemists. She has been awarded multiple honorary doctorates and scientific medals from around the world. Although officially retired, and now in her 90s, Reisfeld is still coming up with new inventions, the most recent being her fluorescent-transparent glass.

Sometimes things happen about which the leaders of the generation remain silent. This does not mean that nothing is to be done… On the contrary: when aware that you are able to do something about it, you are obligated to do so.

Jew of the Week: Raphael Mechoulam

“Godfather of THC”

Raphael Mechoulam

Raphael Mechoulam (b. 1930) was born in Bulgaria to a wealthy Sephardic-Jewish family. The family was forced to flee the country due to rampant anti-Semitism, ultimately surviving the Holocaust and settling in Israel in 1949. During his IDF service, Mechoulam worked as a chemical engineer and helped to develop insecticides. Falling in love with scientific research, he continued to study chemistry after his military service, earned his Master’s from the Hebrew University, then his PhD from the Weizmann Institute. After studies at the Rockefeller Institute in New York, Mechoulam returned to Israel to teach at both of his former universities. His primary field of research is cannabis. In fact, it was Mechoulam who first discovered, isolated, and synthesized THC, the primary active ingredient in cannabis. He would later discover and synthesize other important cannabinoids (a term he coined). Mechoulam was one of the pioneers of medicinal cannabis, and has said that medicinal cannabis could probably replace “ten to twenty percent of all pharmaceuticals”. More recently, he discovered endocannabinoids—molecules similar to THC that are naturally produced by the body, playing a key role in immunity and in regulating human emotions. All in all, Mechoulam published over 350 scientific papers. In 2016, he received a lifetime achievement award at Harvard’s School of Medicine. He was also the subject of an eye-opening documentary called The Scientist. Now a nonagenarian, Mechoulam continues to do research at his Jerusalem lab.

Jewish time sees us as travellers on the road to a destination not yet reached; wayfarers on a journey begun by our ancestors, to be continued by our children.
