 At the urging of the Brisker Rav, Schwadron became a spokesman for the Peylim organization, which promoted the spiritual rescue of Jewish children who had emigrated from Yemen and Morocco and were being housed in absorption camps.In 1952, Schwadron began giving a Friday-night lecture to the public at the Zikhron Moshe shtiebel near the Geula neighborhood of Jerusalem.It was this lecture, which continued for the next 40 years, that earned Schwadron the title of "Maggid of Jerusalem."
