The land that includes the Adelsberger House site traces to March 1816, when William Lemon bought nearly 255 acres covering what is now downtown Waterloo for $2 per acre, then in January 1817 sold his claim to George Forquier and his wife Ann for $127.29, the amount of Lemon’s first installment. George Forquier, with his friend and business partner Daniel P. Cook, helped plan the town of Waterloo. In July 1836 Forquier sold the southeastern quarter of Section 25 to his brother-in-law David Ditch and sister Hannah Ditch, and they later subdivided it and sold Lot #51 to Jesse Wiswell in May 1842 for $200. Tax Lot #51, now the property holding Hopskeller and the Waterloo Chamber of Commerce, made Wiswell the first owner of this specific parcel. In August 1853 Jesse and Sarah Wiswell sold the lot for $500 to William and Cecilia Adelsberger, who soon built a substantial two-story brick home just south of the public square, probably begun in late 1853 or early 1854 and completed by 1855. Although the original floor plan is unknown, the soft brick exterior is original, the foundation suggests four first-floor rooms, and later renovation revealed evidence of two former fireplaces, a sealed coal chute window facing Main Street, a razed outbuilding likely used as a summer kitchen, and a large underground cistern built of the same soft brick. In April 1858 the Adelsbergers sold the home to John Moeller for $3,800. John Moeller and his wife Catharine added the western wing in 1872 and the eastern wing in 1910, the latter now used by the Waterloo Chamber of Commerce; these additions were built for their daughters as they began their own families. The home remained in the Moeller family until 1925, when it was sold to Dr. Justin and Julia McConnell. Dr. McConnell used the second floor as a dental office through the 1960s, while the lower floor became apartments during the 1920s and 1930s. Just before 1970 Glenn Grosse, a great-grandson of John Moeller, bought the property, which then served as a residence, rental apartments, and offices. From 1994 Nancy and Glenn Grosse operated it as the Echoes of the Past antique shop until renovation into Hopskeller Brewing Company began in the summer of 2014.
