Aryeh Yehuda Leib, son of Shneur Zalman and Nehama Teitelbaum, a descendant of Rabbi Moshe Isserles, was born on December 25, 1912 in Polack in what is now Belarus.
In 1932, as a young Beitar member, led a course in self-defense in many cities around Poland, and he was a commander in Brit HaHayil. During a demonstration in the city of Baranovichi, he was attacked by an axe-wielding Shomer HaTza’ir member, giving him a severe head wound. As a result, he spent a year hospitalized in Warsaw.
On September 8,1935 he made aliyah and started working as a porter at the Haifa Port, then as a ghaffir in Zikhron Yaakov. He joined the IZL and took part in retributive attacks in response to Arab terror, as well as smuggling weapons for the underground. In addition, he tried to save Polish Jewry, writing a pamphlet on their behalf. In 1937, after blowing a shofar at the end of Yom Kippur by the Western Wall, he was sentenced to six months in Jerusalem’s Kishleh, where he wrote Notes from Prison.

In 1940, after the split, he followed Yair. In 1941, he was arrested and sent to Mizra. There he wrote Ami-Shaddai, HaMered Ba. After Yair’s murder, he was sent to Acre for more than two years, much of it in solitary confinement. In 1944, he was deported to Eritrea and then Sudan, where he wrote Moshe.
