The 5th Gerrer Rebbe
Under the leadership of the fifth Gerrer Rebbe, Rabbi Yisrael Alter, known as the Beis Yisrael, Ichud Mosdos Gur (the Union of Gerrer Institutions) was established as the responsible body for funding all the educational institutions affiliated with Ger in Israel. Currently there are about 100 such institutions.
The Beis Yisrael put great emphasis on purity and holiness, and rebuilt Ger after its virtual destruction in World War II.
