"ELIAS HEIDELBERGER was born in the province of Baden, Germany, May 11, 1825. He attended school until he was fourteen years of age, when he learned the trade of baking, which trade he followed until he was twenty-one years old, and worked in Prussia, Bavaria, France and other places. In 1847, he came to America and located in Delphi, Indiana, where he began peddling successfully, and was soon able to open a store, which he did in 1851, and on the 15th of November of that year, he married BARBARA FORMAN, of Delphi, by which union were four children - ROSA, FANNIE, LOUIS and CLARA. He sold his business in Delphi to engage in the dry goods trade with his brothers, MOSES and LOUIS, at Pittsburg, Carroll County, which after three years, they transferred to Rock Island, Illinois, comprising of dry goods, notions, furnishings, etc. In 1860, he closed this out, went to Chicago for a time, and afterward resumed peddling in Indiana. In 1863, he began a store at Francesville, Pulaski County, thence moving to Rensselaer, where he continued business for ten years. After living in Attica, Franfort and LaFayette for varying periods, he sold again in 1875, and resumed traveling through Indiana in the general produce trade. In December, 1882, he came to Monon, and began a general store with others, under the firm name of LEOPOLD, HEIDELBERGER & CO."
