This week on Up Close, we look at major Jewish sages, past and present.

Renowned scholar, commentator and translator Rabbi Adin Steinsaltz speaks about his work on the Talmud and his book about the late Lubavitcher Rebbe, My Rebbe, and Dr. Ronald Eisenberg, a physician specializing in radiology, discusses how a side-gig of sorts in digging deep into Jewish studies has yielded his encyclopedic work on Essential Figures in Jewish Scholarship.
