"Brewery.â€”About 1845, Jacob Zelt came to Washington and commenced brewing. Four years later he removed to the west end of Belle Street, and purchased the property he at present owns, and started the brewing in a small way, and by degrees it has been brought to its present capacity. In 1873 the business was placed in charge of his sons, Louis and Adam, who now conduct it. They manufacture about three hundred barrels of beer annually." From.
