In his second lecture for Torah in Motion on Rabbi Moses Kunitz, professor Marc B. Shapiro says: “Even among great Torah scholars, it is usually the case that their reputation declines naturally. Rav Isser Zalman Meltzer, Rav Herzog, Reb Moshe Feinstein, Rav Shlomo Zalman Auerbach. Reb Moshe Feinstein has nowhere near the significance he had in his lifetime. If he did, they would not have put this eruv up in Brooklyn. When he was alive, he was able to stop that.”
“Rav Soloveitchik, Yechiel Yaakov Weinberg, the Chazon Ish, the Ohr Somayach, their reputation just grows and grows.”
