Yiddish culture is experiencing a renaissance in ? of all places ? Madison. At its peak, Yiddish culture displayed incredible diversity in its music and literature, Henry Sapoznik told a crowd Sunday in his opening remarks at A Biselle (?A little bit of?) KlezKamp, a daylong program of Yiddish language, music, dance and arts on the UW-Madison campus. One of the great historical facts about Yiddish, not widely acknowledged, is that in 1916, UW-Madison was the first university in the world to offer a class on Yiddish language, said Sapoznik, director of the UW-Madison?s year-old Mayrent Institute for Yiddish Culture, which put on KlezKamp.
