Jew of the Week: Johann Kremenezky

The Man Who Powered Europe—and Zionism

Yonah Yosipovich Leibensohn Kremenezky (1850-1934) was born in Odessa, Ukraine to a Russian-Jewish family. He studied electrical engineering and worked on designing Russia’s first railways. In 1874, Kremenezky moved to Berlin to further his studies at the city’s Technical University. He then got a job working for Siemens, and was sent across Europe to build the continent’s first street lighting systems, starting in Paris and ending up in Vienna in 1878, where he settled permanently. Two years later, Kremenezky founded his own factory that produced lamps and batteries—the first of its kind in the Austro-Hungarian Empire. By 1883, he had become very well-known as a scientist-industrialist (a European Edison), and Crown Prince Rudolf personally asked him to help “electrify” his empire. Kremenezky did just that, laying electrical cables and setting up lighting systems, as well as building the empire’s first power plant. Meanwhile, his lamp factory designed all sorts of new lights, including ornamental bulbs and what we now know as “Christmas lights”. Kremenezky lights were a huge hit, exported around the world, even to the United States. For playing a key role in rebuilding and repowering Vienna after World War I, Kremenezky was awarded with the Ehrenbürgerrecht, the city’s highest decoration for citizens (a street in Vienna was named after him, too). Meanwhile, back in 1896, Kremenezky had met Theodor Herzl and the two became best friends. Kremenezky became a passionate Zionist, gave countless funds in support of the movement, as well as essential electrical know-how to power the future State. In 1898, he set a 500-franc prize for anyone who would write a fitting hymn for the Zionist movement. This eventually led to the adoption of HaTikvah as Israel’s national anthem. Around the same time, Hermann Schapira proposed the establishment of a Jewish National Fund that would legally purchase land in Israel and help settle Jews there. Schapira didn’t live to realize his dream, but Kremenezky was convinced and established the Jewish National Fund a couple of years later, serving as its first chairman. It was he who came up with the JNF “blue box” to collect charity. The JNF went on to play a central role in the establishment of Israel, purchasing over 50% of Israel’s landmass, developing some 250,000 acres of its land, building nearly 200 dams and reservoirs, and establishing over 1000 parks. Perhaps most famously, the JNF has planted over 260 million trees in the Holy Land, partly thanks to its Tu b’Shevat tree-planting drive which still runs to this day. A true friend, Kremenezky was the only one by Herzl’s bedside when he passed away, and financially supported Herzl’s family afterwards. When Kremenezky himself passed away, he was eulogized as a “simple, modest Jew, who did a great for the Zionist movement.” He was awarded the prestigious Wilhelm Exner Medal for excellence in scientific research and innovation, and multiple institutions and streets in Israel are named after him.

Jew of the Week: Judith Resnik

First Jewish Woman in Space

Judith Resnik - First Jewish Woman in Space

Judith Resnik, the First Jewish Woman in Space

Judith Arlene Resnik (1949-1986) was born in Akron, Ohio to Jewish-Russian immigrants from Ukraine. As a child she went to Hebrew school, then attended a public high school where she was the only female student to achieve a perfect SAT score. She went on to become an electrical engineer, eventually earning a Ph.D in the subject. Resnik first worked as a circuitry designer for tech giant RCA, as well as serving as a biomedical engineer for the National Institutes of Health (at the Laboratory of Neurophysiology) and a systems engineer for Xerox. In 1978 she joined NASA, going on her first space flight in 1984 on the maiden voyage of the space shuttle Discovery. That made her the first American Jew in space and the first Jewish woman in space. She quickly became beloved by the public for her on-board humour and space acrobatics. Resnik went on her second tour in space with the Challenger in January of 1986. Sadly, the mission ended quickly when the space shuttle tragically exploded in Earth’s atmosphere, killing all 7 crew members. It took nearly 6 weeks to find the crew compartment at the bottom of the ocean floor. Resnik’s body was among those that were identifiable. She was laid to rest in Arlington National Cemetery. That same year, the Institute of Electrical and Electronics Engineers (IEEE) established the Judith A. Resnik Award for outstanding contributions to space engineering. The moon’s Resnik Lunar Crater is named in her honour.

Jews of the Week: Nathan Rosen & Brian Podolsky

Podolsky and Rosen

Nathan Rosen (1909-1995) was born in Brooklyn and studied at MIT during the Great Depression. While still young, he published several famous papers, including ‘The Neutron’, which predicted the structure of the nucleus a year before it was discovered. Between 1935 and 1945 he was Albert Einstein’s personal assistant at Princeton. Together, they discovered (mathematically) a “bridge” connecting distant areas of space – now called a wormhole. With Einstein’s encouragement, Rosen moved to the nascent State of Israel and joined Haifa’s Technion in 1953. He later served as President of Ben-Gurion University, founded the Israel Academy of Sciences and Humanities, the Physical Society of Israel, and the International Society for General Relativity and Gravitation. Aside from all this, he is most famous for coming up with the well-known “EPR Paradox” together with Einstein and a fellow Jewish scientist named Podolsky (hence “EPR”).

Boris Yakovlevich Podolsky (1896-1966) was born in Russia to a poor Jewish family which immigrated to the U.S. in 1913. He served in the US Army and worked as an electrical engineer before returning to school and earning a PhD from Caltech. In 1933 he was given a fellowship at Princeton, which led to his collaboration with Einstein and Rosen on the EPR Paradox. Interestingly, some have suggested that Podolsky was a Soviet spy, codenamed “Quantum”, and helped the Soviets start their nuclear program during World War II. His major legacy, however, is in the great work he did on solving various complex physics problems of the day.
