Balthasar Ludwig “Louis” Schmidt (1835-1908) was one of the original Schmidt immigrants to come from Machtlos, Germany and settle in America. Louis ended up in Washington, DC, where he operated a popular restaurant/tavern on Seventh Street NW from 1875 until his death (after which the business was carried on by his son Milton until Prohibition put them out of business).
