Rav Reuven Margulios Margoilyos Hayam

Rav Reuven Margulios (1889-1971). His published works range from biographies and history books to discussions of the behavior of Talmud sages, including behavior which is seemingly unusual, and explain it in light of those sages' halachic opinions. It truly appears that there was no section of Shas or Midrash, no Rishon or Acharon, and no aspect of kabbalah which was not at Rav Margalios's finger tips. His works include Malachei Elyon (an encyclopedia on angels), Margoliyos Hayam (a commentary on Meseches Sanhedrin), Nefesh Chayah (a commentary on Shulchan Aruch), Nitzotzei Zohar (a commentary on the Zohar and Tikunei Zohar), Olelos (essays on Tanach, Shah, the siddur and history), and many others.
