my favorite artcroll biographies are those written about the great sefaradi gedolei hador like rav ezra attia and rav yosef chaim. what a good read. i also enjoyed the one about rav soleiman eliyahu very much. also, the one about rav bentzion abba shaul was compelling. also, artcroll wonderful biography about rav yotzchak nissim was simply awe inspiring. artcrolls wonderful biography about rav yehuda tzadka should win a pulitzer this year. i particularly enjoyed the biography that artcroll published about Rabbi Chaim Falagi.
Oh, wait, artcroll never published any of those. hmmmmmmmmmm…..
