Jew of the Week: Erwin Chargaff

Discovering DNA Structure

Erwin Chargaff (1905-2002) was born in what is now Chernivtsi, Ukraine (then part of the Austo-Hungarian Empire). His family was of the little-known Bukovinian Jewish community that blended elements of Ottoman, Romanian, Austrian, and Ukrainian culture and had a mix of Ashkenazi and Sephardi heritage and practice. During World War I, the family moved to Vienna, where Chargaff went on to study chemistry. In 1925, he took a job as professor of organic chemistry at Yale University. He moved to the University of Berlin in 1930 to head the chemistry lab for the bacteriology and public health department. During this time, he made some important findings about bacterial membranes and lipids. When the Nazis came to power, Chargaff was forced to resign and fled to Paris. After spending a couple of years doing research at the Pasteur Institute, Chargaff returned to the States to become a professor at Columbia University for the next four decades. This is where he did some of his most famous work, including on the mechanism of blood clotting. His main focus, however, was on the chemistry of mysterious DNA. He soon discovered that DNA always contained equal amounts of the nitrogen bases adenine and thymine, and equal amounts of cytosine and guanine, suggesting that the two sets pair up. (This would become known as the first of “Chargaff’s Rules”.) His 1950 paper was instrumental in allowing Watson and Crick to solve the puzzle of DNA structure just a few years later. In fact, it was a conversation that Chargaff had with Watson and Crick in 1952 which led them to deduce DNA’s double-helix structure. Not surprisingly, Chargaff protested when Watson and Crick won a Nobel Prize while he was excluded. Chargaff did win many other prizes, including the Pasteur Medal, the Heineken Prize, and the National Medal of Science. After retiring from Columbia, he continued to do research at the Roosevelt Hospital until the age of 87! Chargaff was highly critical of genetic engineering and biotechnology, saying that it would inevitably be abused and lead to a “molecular Auschwitz”. (Many today would say he was right!) Chargaff is often considered one of the fathers of biochemistry, and “Chargaff’s Rules” are still a fundamental concept taught in biology classes today.

There are two nuclei that man should never have touched: the atomic nucleus and the cell nucleus. The technology of genetic engineering poses a greater threat to the world than the advent of nuclear technology.

Jew of the Week: Nathan Birnbaum

The First Zionist (and the First Modern Ba’al Teshuva)

Nathan Birnbaum (1864-1937) was born in Vienna to a traditional Jewish family of Hungarian and Galician heritage. He studied law and philosophy at the University of Vienna, where he founded Kadimah, the first nationalist Jewish student association. He also started a new magazine called Selbstemanzipation! (“Self-Emancipation!) In fact, it was in an 1890 article for his magazine that Birnbaum coined the terms “Zionism” and “Zionist”. Two years later, he coined the term “political Zionism”, as distinct from the religious Zionism that has always existed in Judaism. Birnbaum’s writings were hugely popular and helped ignite the modern Zionist movement. They also played a role in inspiring Theodor Herzl. At the First Zionist Congress in 1897, Birnbaum was elected Secretary General. However, he soon had a change of heart when he saw how Zionism was becoming too secular and too political. Instead, he began to advocate for “Jewish cultural autonomy”, also called golus (or galut) nationalism. He hoped Jews would be recognized as a distinct and semi-autonomous people within the countries in which they dwelled. Birnbaum ran for Austrian parliament and while he did win the election, corruption and anti-Semitism prevented him from taking his seat. Birnbaum was a huge proponent of “Yiddishism”, and to make Jews proud of their culture and language. In 1908, he convened the first Conference for the Yiddish Language, and even traveled to America to promote the revival of Yiddish. During this trip, he had a meeting with US President Teddy Roosevelt. Birnbaum eventually realized that true salvation for the Jews can only come from adherence to Torah and Jewish law. In 1916, he became a ba’al teshuvah and began to live a strictly Orthodox life. Three years later, he became the General Secretary of Agudas Yisroel (originally an umbrella organization for Eastern European Orthodox Jews, and today also a political party in Israel). He wrote a popular text called Gottesvolk (“God’s People”), where he outlined his plan for reviving Judaism and laid out a vision of the ideal Jewish community. He argued passionately against “modern paganism” and warned about the dangers of godless secularism, quite accurately foreseeing how it could destroy society. He affirmed that settling and living in Israel was still important, of course, but for spiritual reasons, not political ones. When the Nazis came to power in 1933, Birnbaum fled with his family to the Netherlands, where he lived out the last few years of his life. Today there is a street in Jerusalem named after him. He has been called a “prophetic personality” and the “first modern ba’al teshuvah”.

When one stands in prayer, he should place his feet together side by side. He should set his eyes downwards as if he is looking at the ground, and his heart upwards as if he is standing in Heaven.

Jew of the Week: Gamliel Cohen

Father of Israeli Espionage

Gamliel Jamil Cohen (1922-2002) was born in Damascus to a religious Syrian-Jewish family, and grew up in the city’s Jewish Quarter. Yearning to live in the Holy Land and inspired by the Zionist vision, he left Damascus at the age of 21 and literally walked to Israel. He joined a kibbutz started by Ashkenazi immigrants. Despite being the odd one who was darker-skinned and spoke no Yiddish, Cohen quickly fell in love with the sense of unity and brotherhood, as well as the important pioneering work of developing the Jewish ancestral homeland. His uniqueness caught the attention of the Palmach, the commando unit of the pre-IDF defence force, the Haganah. The Palmach sought to launch an intelligence unit that could infiltrate Arab governments, and were looking for talented and dedicated Arab Jews. In 1944, Cohen became their first recruit. Together with Iraqi Jew Shimon Somech, they created the first unit of Mista’arvim (recently popularized by the show Fauda). The term itself came from the name of the ancient Mizrachi Jewish communities living in Arab lands that were distinct from, and pre-dated, the Sephardic Jews that joined them after the Spanish Expulsion of 1492. After several years of training, Cohen moved to Beirut in 1948 and set up Israel’s first official intelligence outpost, living undercover as Yussef el-Hamed, a textile shop owner. By this point, his operation was overseen by the newly-formed Mossad. Cohen’s trailblazing work and espionage innovations paved the way for more famous later spies like Shula Cohen and Eli Cohen. In 1954, Cohen married a fellow Syrian Jew who also worked for the Mossad. Together, they moved to Paris undercover as Arabic journalists. Cohen managed to get hired by the Syrian Embassy in Paris, from which he sent critical intelligence to the Israeli government. In 1958, the Cohens moved to Vienna to continue their work as “journalists”. In addition to infiltrating the embassies of Arab states, they also found information on neo-Nazi groups and exposed war criminals in hiding. Cohen retired from active duty in 1964 and went on to train the next generation of Israeli spies. In his last years, he wrote the book Undercover: The Untold Story of the Palmach’s Clandestine Arab Unit. Almost all of Cohen’s work remains classified. He has been called the “father of Israeli espionage”.
