Chaim-Meir Gegner or Gegna (Yiddish: חײם מאיר געגנער, c. 1860–1916) was a Russian Jewish violinist, klezmer bandleader and composer from Bila Tserkva. He was one of the celebrity Jewish violinist-composer-bandleaders of 19th century Ukraine, which included such figures as Pedotser, Stempenyu and Alter Chudnover. Several of his sons emigrated to the United States and become professional musicians, including the violinists Naum and Jacob Gegna and the cellist Max Gegna.[1]
