Kehot Publication Society is the publishing division of the Chabad-Lubavitch movement. History Kehot was established in 1941 by the sixth Rebbe of Chabad-Lubavitch, Rabbi Yosef Yitzchak Schneersohn. In 1942, Rabbi Yosef Yitzchak appointed his son-in-law, Rabbi Menachem Mendel Schneerson (who became the seventh Rebbe in 1951) as director and editor-in-chief. Prior to the establishment of Kehot, printed editions of Chabad texts were limited. Since its founding, Kehot published many volumes of both Hasidic texts and general Jewish literature, growing significantly as an established publisher of Jewish books published in Hebrew, Yiddish, English, Russian, Spanish, French, Italian, Portuguese, Dutch, German, Persian and Arabic. Rabbi Menachem Mendel served as editor for many of the early Kehot publications. In a 1946, he wrote of his editorial work for Jewish holiday literature published in French and in English. He edited both Jewish educational literature for children as well as volumes of Hasidic discourses. Rabbi Menachem Mendel also worked on publishing old manuscripts from the previous Rabbis of Chabad. In the first years he mainly focused on the works of the fourth Chabad Rebbe, the Rebbe Maharash also writing a biography on his life. Rabbi Schneerson also published the encyclopedic work of Chaim Hezekiah Medini the Sdei Chemed, with rearranging it and adding indices In 1956 he began publishing the discourses of the First Lubavitcher Rebbe the Alter Rebbe, a project he later related as "time consuming".
