Chabad history: Rabbi Yisrael Arie-Leib (Label) — Rebbe's brother
Community
🧠 Childhood of a child prodigyLeibl was born in 1906 in Mykolaiv. From early childhood, he impressed those around him with his phenomenal abilities. Already at the age of three, he knew whole chapters of the Mishnah by heart, being an absolute autodidact with a brilliant photographic memory. His mother, Rebbetzin Hana, often said that she had to literally pull him away from his books by pulling his sleeve to force him to eat. His father, Reb Levi-Yitzchak, said of him: "He has the head of Tsemach-Tzedek" (the Third Lubavitch Rebbe, who was famous for his outstanding intellect).There was a unique division of thinking styles in the Schneerson family. Contemporaries recalled that when the three of them communicated, the father spoke the language of mysticism and the Cabal, the Rebbe spoke the language of Hasidism, and the Label analyzed everything through the prism of philosophical research.🕵️♂️ Escape, someone else's name and the self-sacrifice of the familyIn 1930, when a ring of Soviet intelligence services began to squeeze around the family of Rabbi Levi-Itzhak, Label was forced to flee. He crossed the border according to the documents of Mark (Mordechai) Gurariy, a Hasidic young man who had recently drowned in the river. From then until the end of his life, Israel Arie-Leib lived under this name.In Berlin, he fell seriously ill with typhus. The Rebbe and Rebbetzin Khaya-Mushka gave him their bed in a tiny apartment and nursed him until he fully recovered. Later, when Leibl needed documents to repatriate to Eretz Yisrael while in Paris, Rebetzin Chaya-Mushka showed incredible self-sacrifice. She personally went to Nazi Germany, risking her life to obtain for him the necessary certificates from the state institutions of the Third Reich.🌴 Living in Tel Aviv: modesty and insightArriving in Eretz Israel in 1935, he settled in Tel Aviv. For most, he was a humble librarian and the owner of a small shop on Nahalat Benyamin Street. Only a few knew who he really was.When the Rebbe published his first work, the Ayom Yom calendar, in 1943, the Label received one copy. After reading it, he enthusiastically said that he had always known about the light mind of his brother, but did not even know about such a scale, and that it was a pity that the world did not yet know what was hidden behind the pages of this book. It was Label who, realizing the scale of his brother's personality, asked the influential Hasidim to do everything possible so that after the departure of Rebbe Raiats, it was our Rebbe who would become the next Rebbe.⚛️ Secret Mission: Nuclear ProjectThe most intriguing part of Israel Arie-Leib's biography begins in the late 1940s. According to testimony, he became the first research scientist at the Weizmann Institute in Rehovot. He had no formal higher education in physics, but his ingenious mind was thinking in formulas.In 1950, with the support of future Israeli President Zalman Shazar and Prime Minister David Ben-Gurion, he was sent to Liverpool. Officially — to complete studies at the university. Unofficially, he wrote a unique article on nuclear physics, which he sent to the British Atomic Energy Commission. It was only on the basis of this article that he was invited to join their work. Historians believe that the Label was part of a top-secret group that laid the foundation for Israel's future nuclear program.💔 Sudden withdrawal and 12 years of secrecyHis life ended tragically early. In 1952, at the age of 43, he died in Liverpool of a heart attack. Shortly before his death, he spoke for two hours with the chief rabbi of Liverpool, and the rabbi agreed to give the details of this conversation only personally to the Lubavitcher Rebbe, which indirectly confirms the secrecy of his scientific activities.Label's death was a heavy blow to the Rebbe. But he was even more worried about his mother, Rebbetzin Khan, who had already lost her husband in exile in Kazakhstan and her youngest son, Dov-Ber, killed by the Nazis. The Rebbe made an unprecedented decision: he hid the death of her son from the mother. For 12 years, until the death of Rebbetzin Hana, the Rebbe regularly wrote letters to her on behalf of the Label and sent them through Europe so that they would bear the appropriate postmarks.InheritanceAfter Label's death, Rebbe handed over his notebooks on higher mathematics to the American professor Rosenblum for publication. The Rebbe noted an interesting detail: his brother liked to derive all the formulas independently, and only then looked for confirmation in the scientific literature.The body of Israel Arie-Leib, on the personal and very detailed orders of the Rebbe, was transported to Israel and buried in the ancient cemetery at Safed. Today, thousands of Hasidim come to his grave on the anniversary, remembering a man who combined Hasidic depth and outstanding scientific genius.source: 📖 Lubavitsky Calendar (https://t.me/+8KbDy9dQVqAxZWE8)
