 Anshe Sholom Bnai Israel Congregation began its long record of service to Chicago's Jews with a fight over a hat.One hot day in the summer of 1870, Duber (Dov Ber) Ginsburg, an immigrant from Mariampol, Lithuania, appeared for services at the Bais Medrash Hagodol synagogue wearing a straw hat, but the leaders of the shul took exception to its frivolity and threw him out.Offended, Ginsburg assembled a minyan from his old-country friends, and founded a competing shul, Ohave Sholom Mariampol, at Polk and Dearborn Streets.
