Today, 219 years ago, in the year 1801, Rabbi Shmuel Falkenfeld, was accepted as rav in Poznań.
Rabbi Shmuel Falkenfeld, better known as the Beis Shmuel Acharon, was the younger brother of Rabbi Yosef HaTzadik, the famous son-in-law of the Noda beYehuda. R’ Yosef was rav in Poznań. Around 6 months after R’ Yosef’s passing, the Poznań community decided to give over the mantle of leadership to his younger brother the Beis Shmuel Acharon.
