Abe Schwartz (1881–1963) was a well-known klezmer musician of the 1920s. Schwartz was born outside of Bucharest, Romania, and moved to the United States in 1899. He soon distinguished himself as a talented arranger and composer of music, as well as a violinist, pianist, and bandleader. The famous klezmer clarinetist Naftule Brandwein played for a time in Schwartz's ensemble, notably on popular songs like Brandwein's own "Firn Di Mekhutonim Aheym" (Leading the In-Laws Home) and Schwartz's "Di Grine Kuzine" (The Greenhorn Cousin). These compositions are still played today by klezmer revivalists.
