(l-r Rabbi Morris Sherer, Rav Yitzchok Hutner, Rav Yaakov Kamienecki, Journalist R' Gershon Ber Jacobson.) Sruli Besser says: "There are many things about Rabbi YY Jacobson that are special; it's an honour to tell the story of a chassid who's capturing the hearts & minds of all sorts of listeners. The backstory of his father is incredible - this picture, of Reb Gershon Jacobson with Rav Hutner, Rav Yaakov and Rabbi Sherer, is thrilling; it captures the flavor of a different time."

Rabbi Goren was some 12 years younger than Rav Hutner, but they were acquaintances. The latter only leaving the Holy Land in approximately 1930. The former already being a talmid in the Chevroner Yeshiva at that time. And RYH again spending a year or so in the Holy Land some years later. Maybe they attended Rav Kook's shiurim together? The man in the middle is hitherto unknown. At least to me. UPDATE: Friday. Reb YD Miller tells us that this is Rabbi Menachem Tzvi Eichenstein, (1910-1981) Chief Rabbi of St. Louis.
