Siddur Torah Or, prayers according to Nusach HaAri and following the rulings of Ba'al HaTanya, published by the worldwide Chabad Chassidism association. Brooklyn, [1941].
The well-known edition of Siddur Torah Or, edited by Rabbi Avraham David Lavat. Reputedly, the Rebbe the Rayatz gave this edition as a gift to his son-in-law, Rebbe Menachem Mendel Schneerson of Lubavitch, the Chabad Rebbe, and he used it every day.
Later, more editions of Siddur Torah Or were printed but the 1941 edition has several variations from the others. For example, at the end of the 1941 edition, another section appears with Rosh Hashanah and Yom Kippur prayers containing piyyutim and the repetition of the Shatz (leader of the prayers) which seldom appear in a siddur, but rather in machzorim for the High Holidays.
