During 1855-1856 Jacob Maurer of Hesse Darmstadt, Germany, constructed a three-story building with two ground-floor storefronts and residences above. He opened for business in 1856, selling hardware on the west side and dry goods on the east side. In 1863 he sold the east side to Jacob Stoltz for a dry goods and grocery store while continuing to own the west storefront for his hardware business. Ownership of the building's east and west sides was often split afterward, with different owners and businesses occupying each side. Maurer added onto the west storefront in 1863, changing the building's configuration, and further additions followed. In 1937 the New Era Oil Company's lubrication garage was added behind the east storefront, and in 1939 building owner John T. Thomas removed the top two stories of the original building. During the building's first hundred years, its storefronts housed a wide range of businesses, including the Francis Stoltz hardware store, shoemaker Charles Deobald, grocer and dry goods merchant Julius C. Koska, tinsmith J.H. Doering, Mayer Marglous's dry goods, Star Tire Store, Sutton's Sweet Shop, Lill's Wall Paper and Stationery, Char-Main Tavern, Kohl's Sweet Shop, and Belleville Office Supply. By 1959 Paul Reis had moved Grimm and Gorly Florist into the east side and bought that property in 1962; after purchasing New Era Oil's grease palace in 1967, he connected the storefront with the garage. In 1999 Jeffrey Bair bought Grimm and Gorly and its building. Travel agencies came to the west side in 1972, and travel agent David Bollone bought that storefront in 1986 before later selling the business and property to Kenneth Fischer. In 2011 the Bairs restored single ownership of the building when Zachary Bair bought the west side, and in 2014 he opened the Pour@322 and Cupcakes Too coffee shop there.
