Among the most remarkable, yet barely known, sages of the 1900s is surely Rav Reuven Margaliot. His works cover all areas of Torah study, and in a style which is truly unique.
Many of Rav Margaliot's works adopt the tools of "Bible criticism" in the service of true Torah study. It truly appears that there was no section of the Talmud, no midrash, no rishon (medieval commentary), no acharon (post-medieval commentary), and no aspect of kabbalah which was not at Rav Margaliot's finger tips.
