Rabbi Chaim Yehoshua Kosovsky (1873-1960), the author of many books and essays. Was known as 'The Author of the Concordances' due to his great work on various concordances. A well-read, knowledgeable person. He was born in Jerusalem to his father, Rabbi Avraham Avly, a rabbinical judge of the first rabbinical court of the Ashkenazi community. He studied at Etz Chaim Talmud Torah and Yeshiva. As a youth, he was considered a unique prodigy so much so that he was given a room in the attic of the Hurva synagogue so he could study without interruption. When he was a youth, he insisted on speaking only Hebrew and due to his love of the language, composed, over the years, various concordances to enrich it. His compositions evoked admiration among religious circles and wider ones. The poet Bialik wrote to him: "Your great enterprises … evoke amazement and admiration. It is unbelievable that in the hand of one man had done all this".
