Aryeh was born to Binyamin and Malka on 17.5.1915 in Vilnius, Lithuania, in the Tushia Hebrew Gymnasium, where he acquired a general and Jewish education. When he finished his studies, he went to a training farm to learn how to raise bees. The family lived in a large home which the grandfather, Rabbi Binyamin, had built. The father was pleasant and good-natured, while the mother was an excellent baker who was well-educated and generous to those in need. His brother Hayim finished his studies at Vilnius University.

In 1935, Aryeh made aliyah to study at Jerusalem’s Hebrew University, majoring in philosophy and minoring in Hebrew literature and studies of the Land of Israel. In Jerusalem, he immediately found his place with his teachers, his fellow students and his coworkers. In 1936, as the riots broke out, he was sent to guard the city’s neighborhoods.

In 1942, Aryeh enlisted in the British Army, and he was sent to Egypt for professional training. He was a surveyor for Unit 744 of the Royal Engineering Corps and Unit 1039, who served in the Port of Alexandria. While he was serving in the British Army, he joined Lehi. The activity in Egypt was intensive: recruiting members, organizing chapters, firearms smuggling, and more. In 1944, before the Lord Moyne assassination, the two Eliyahus would receive any help they needed for their mission from Aryeh.

On 17 May 1945, Aryeh was arrested by the military police and taken by rail to be interrogated in the Land of Israel. Along the way, he jumped out, showing up a few days later to meet Lehi Central Committee member Yitzhak Shamir. After their discussion, Shamir gave him the leadership of Lehi’s recruitment division.

When the State was established, Aryeh joined the IDF, serving in Battalion 82 of the 8^th Brigade, under the command of Yitzhak Sadeh.

After the war ended, he became the secretary of the clerks’ union of the Histadrut in Tel Aviv. A few years later, he and his wife, Zipporah née Kempler, established a farm in Kfar Shedma.

Their daughter, Millie Gallon, followed in her parents’ footsteps, completing her studies in agriculture. She and her family, with her four children, were among the founders of the settlement of Yakir in Samaria. Their older daughter Hannah was killed in a road accident while she was a university student.
