He is the Kaliver Rebbe.
[Rabbi] Menachem Mendel Taub (born 1923) is the Rebbe of the Kaliv Hasidic dynasty. Born in Transylvania in 1923, he is seventh in a direct paternal line to the founder of the dynasty, Rabbi Yitzchak Izak of Kaliv, a disciple of the Rebbe Reb Elimelech of Lizhensk.
An extremely talented Rabbi who recently moved his headquarters from Bnei Braq to Jerusalem. He speaks quite a few languages, and as a survivor of Auschwitz, he regularly speaks passionately about the Holocaust and Jewish unity. As a twin, Dr Mengele experimented on him and his sister (who didn't survive).
As a Chassidic Rebbe, he regularly conducts tischen where his Chassidim will join him for his meal. This particular picture is likely on Tu B'Shvat when Rebbes are known to distribute fruit.
And, video caption aside, he is NOT anti-Zionist!
