Originally, all of the sanctuary windows were glazed with clear glass. In 1898, the congregation voted to start installation of memorial stained glass windows created by the studios of Louis C. Tiffany, and commissioned a set of designs for all 20 windows. The last of 16 Tiffany windows was installed in 1929, just before the Great Depression dried up available funds. By the time the economic crisis had eased, Tiffany Studios had been liquidated (in 1937), and new Tiffany windows were unobtainable.
