During my visit today with Chief Rabbi Shapira, he told me the following story to which he was a personal witness.
When Rabbi Soloveitchik came to visit Israel, the one and only time during his life, in the 1930s, it was the last year of the life of Rabbi Kook, the Elder.
Rabbi Soloveitchik spoke in several places – at Mercaz Harav, at the Harry Fischel Institute, and at several other yeshivot. At every lecture that he gave, Rabbi Kook’s son, Rabbi Zvi Yehuda Kook, attended and listened attentively.
When Rabbi Shapira asked the younger Rav Kook why he was doing so, he answered as follows: His father had received Rabbi Soloveitchik and they “talked in learning.” When Rabbi Soloveitchik left, the elder Rav Kook told his son that the experience of speaking with Rabbi Soloveitchik reminded him of his earliest years, when he was a student at the Yeshiva of Volozhin, during the time that Rabbi Soloveitchik’s grandfather, Rabbi Hayyim Soloveitchik, first began to give shiurim. I believe, the elder Rav Kook said, that the power of genius of the grandfather now resides with the grandson – and therefore, he said to his son, you should not miss a single sheur by Rabbi Soloveitchik.
