Abraham Lewin was born in 1893, in Warsaw. His family belonged to the Chassidic movement. He had no degrees, but owing to his intellectual capacities Lewin was named professor of Hebrew and Jewish Studies in 1916, at the great Yehudya Secondary School for Girls. He abandoned his Orthodox ideas and became a Zionist. In 1925 and 1926, he made two trips to Palestine and gave a series of conferences in the presence of Hechalutz activists. In the 30s, he received his teaching certificate and published an essay on Jews forcibly enrolled in the Czar's armies. After the German invasion, classes continued secretly in the Yehudya School. Abraham Lewin now became one of the leaders of the Jewish Self-Help Committee, directing one of the five districts. He was also a member of Oneg Shabbat, founded by Emmanuel Ringelblum. His Journal covers the period from 26 March 1942 to 16 January 1943 and is considered as one of the major chronicles of the Warsaw Ghetto during the last period of his life in OBW (the shop of Alexander Landau) Hidden inside the Oneg Shabbat's crates, only the last part was recovered. Abraham Lewin continued his writing, even during the hardest times, when his wife was deported to Treblinka. He was murdered some time between January 18 and 22 January 1943.
