[2] Krohn is known as the author of a series of "Maggid" books inspired by the stories of Rabbi Sholom Schwadron, who was known as the "Maggid of Jerusalem" for the inspirational mussar talks he gave every Friday night from 1952 to 1992 to the public at the Zikhron Moshe shtiebel in Jerusalem.
When Schwadron announced that he was leaving after Passover 1965 to travel back to Israel by boat, the entire family saw him off at the pier.
[4] A few days later, Krohn's father said he missed his guest so much that he decided to greet him when his boat docked in Israel.
[5] Avrohom Zelig Krohn was diagnosed with a terminal illness after this event, and died the following year.
[6] He showed sensitivity towards Krohn's widow, remembering his own mother's struggles to raise her orphaned children.
Along with Esther Jungreis, Krohn has served as a guest speaker at the annual Shavuot retreat hosted by Gateways since 2005.
[12] Krohn's wife, Miriam, is one of the principals of Shevach High School in Kew Gardens Hills, Queens, New York.
