Sigmund Freud and Lubavitcher Rebbe RaSHaB

During the celebration of the birthday of Rabbi Shalom Dov-Ber Schneersohn, the 5th Lubavitcher Rebbe (known by the acronym RaSHaB) on the 20th of Marcheshvan past week, Hasidim spoke about a visit by RaSHaB with his son Rabbi Josef Yitzchak Schneersohn (known by the acronym RaYaTZ) to Vienna to see non other but Dr. Sigmind Freud! I could not believe that the event could have taken place because of timing. The only politically possible window of the first decade of the past century preceded Dr. Freud's fame. The details apparently became clear after the publication of Diaries (R'Shimos) of the late Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson in 1997. This paper sheds lights on the mysterious sojourn by RaSHaB .
