Ger, or
Gur (or
Gerrer when used as an adjective) is a
Hasidic dynasty originating from Ger, the
Yiddish name of
Góra Kalwaria, a small town in
Poland. The founder of the dynasty was Rabbi
Yitzchak Meir Alter (1798–1866), known as the
Chiddushei HaRim after his primary scholarly work by that title.
