Aharon Yehuda Leib Shteinman (1914-2017) was born in what is now the city of Brest, Belarus. To avoid being conscripted into the Polish army, the young yeshiva student fled to Switzerland with some classmates. He continued his diligent studies in a Swiss yeshiva until being arrested during World War II and sent to a labour camp. Shteinman was the only member of his family to survive the Holocaust. He settled in Israel after the war. There, the young rabbi quickly made a name for himself as a Torah prodigy, and was soon appointed rosh yeshiva, head of a Torah academy. He would serve as a rosh yeshiva for the next five decades, while also establishing a number of children’s schools for the underprivileged. Meanwhile, Rav Shteinman wrote profusely, authoring dozens of bestselling books and discourses on Torah, Talmud, and Jewish thought, as well as being recognized as an expert in the field of education. While abstaining from politics himself, Rav Shteinman was the spiritual leader of Israel’s Degel HaTorah party, playing an influential role in government. In his 90s, and in frail health, the Rav decided to journey around the world to strengthen Jewish communities. Countless thousands gathered to greet him and hear his wise words in Los Angeles, New York, Mexico City, Buenos Aires, Manchester, Odessa, Berlin, Gibraltar, Paris, and many more small towns. On these trips, he would give as many as 10 talks a day.
Rav Shteinman was known for his extreme piety, humility, and modesty. His daily diet was nothing but a cucumber, a boiled potato, and one small bowl of oatmeal. He lived in a tiny apartment, with little furniture but walls lined end to end with books. He slept on the same thin mattress that was given to Jewish refugees upon arrival in Israel for some 50 years. Streams of people lined up at his open door each day seeking counsel and blessings. Rav Shteinman stood only for truth, even when it brought him adversity. This was particularly clear when he supported the Nachal Charedi, an IDF unit for yeshiva students. Even after some backlash from ultra-Orthodox communities, the Rav stood his ground and continued his support. He was widely recognized as the gadol hador, the world’s chief rabbi. Sadly, the great rabbi passed away yesterday, at 103 years of age. (His condition had turned critical two weeks ago after the tragic death of his 72-year old daughter from a heart attack, even though no one had told him of her passing.) Rav Shteinman wrote in his will that it would suffice to have just ten men to carry out his funeral, and requested no eulogies. Nonetheless, the funeral procession brought over 600,000 people. Israel’s President Reuven Rivlin stated that Rav Shteinman “bore the entire weight of the Jewish people’s existence on his shoulders… he knew how to convey his ideas gently, in a pleasant manner, and with a great love of the Jewish people… He was a man whose wisdom was exceeded only by his humility.”

The streets of Bnei Brak fill with hundreds of thousands of mourners for Rav Shteinman’s funeral procession.


Arno Allan Penzias (b. 1933) was born in Munich. As a six year old, he was evacuated from Nazi Germany through the British Kindertransport rescue operation which saved 10,000 Jewish children. He was later reunited with his parents, who brought the family to New York. Penzias grew up in Brooklyn and went on to study physics. He graduated among the top of his class, then served two years in the US Army as a radar officer. From there, he got a research position at Columbia University’s Radiation Lab, where he helped to develop the maser (a “microwave laser”). After earning a Ph.D in physics from Columbia, Penzias got a job at Bell Labs to do astronomy research with microwave receivers. He was soon joined by Robert Wilson. The two noticed their antenna picking up an inexplicable signal. After ruling out all forms of interference, and carefully cleaning the antenna, the weak signal persisted. The two collaborated with another physicist, Robert Dicke, to show that this signal was the cosmic microwave background (CMB) radiation, the remnants of the universe’s birth, as predicted by the Big Bang Theory. The existence of CMB confirmed that the universe had a beginning, with a burst of radiation, and simultaneously confirmed ancient Jewish teachings about the universe’s origins. The Zohar, a famous mystical commentary on the Torah that was first published some 700 years ago, explains that the universe began with a nikuda hada d’zohar, a singular point of radiance, from which all things were formed. The Zohar explains that this ever-expanding radiance continues to fill the universe, based on the words in the Biblical Book of Daniel (12:3) which describes the “radiance of the firmament”. In fact, this is how the book got its name, Zohar meaning “radiance”. Penzias’ and Wilson’s monumental discovery brought about a beautiful harmony between Torah and science, at once confirming both the modern Big Bang Theory and the holy words of the ancient Jewish Sages. The two physicists won the 1978 Nobel Prize in Physics. Penzias continued his work at Bell Labs for a total of 37 years, rising to the position of Vice President of Research. He was made a Fellow of the American Academy of Arts and Sciences, and the National Academy of Sciences. Penzias later moved to Silicon Valley to advise venture capitalists and tech start-ups. Despite being in his 80s, he is still a venture partner at New Enterprise Associates, and says he has “no plants to retire”.
