History runs deep at Chicago-based Alpha Baking Co. Inc. Its iconic S. Rosen’s brand traces its roots back to 1909, when Samuel Rosen moved to Chicago in his early 20s, and began baking his Old World hearth rye breads and delivering them throughout the city via horse and buggy. He had been honing his craft since age 9, when he left his home in Poland to apprentice with a baker in Germany, eventually making his way to New York at age 13.
