R’ Moshe Ernster shlit”a opened his beis hamedrash in Sanhedria Hamurchevet in 1974. He immediately opened a kollel there which was somewhat novel in requiring the bnai kollel to sign in and out.
His oldest son, R’ Velvel was the Rav in a Viznitzer shteibel in a nearby neighborhood. When R’ Moshe established a Viznitzer settlement in Tzfas and relocated there, R’ Velvel assumed the role of Rav in Sanhedria Hamurchevet. He is not the SIL of the Veitzener Rov of Chicago, but a SIL of the Uheler Rov (brother to the Veitzener).
The extended Ernster family is well known, and are a bunch of really wonderful people. The Ernster home in Yerushalayim was a open home, full of guests every Shabbos. R’ Moshe was a known baal tzedokoh when I was there long ago.
His second son, R’ Menachem is a SIL of the Yeshuos Moshe, and is Rosh Hayeshiva of Viznitz in Bnei Brak. Third son is R’ Yisroel in Boro Park. Fourth son is R’ Eliezer in E”Y. The one son-in-law is R’ Yisroel Eliezer Adler (his mother was another daughter of the Imrei Chaim), who was recently named Dzikover Rebbe. The Ernster family is known for its achdus, and, as such, is a model for rebbishe families world over who can learn from them.
