It was believed to have been designed by Albert Pretzinger, brother of the owner and head of the Dayton architectural firm Peters and Burns. It was built for Rudolph Pretzinger, a successful Dayton druggist.","narrative":"Built in 1889 at the corner of South Main and Apple Streets in Dayton, this two-story brick house is a well-preserved Queen Anne residence. It sits on a steep hillside behind a cut limestone retaining wall, with a rockface limestone foundation. A round corner tower with a candle-snuffer roof anchors the facade, beside a projecting pavilion with paired semicircular arches, a Palladian window and strapwork. The roof is complex, with a central hip and side gables. Rudolph Pretzinger, a German-born pharmacist, had it built for his bride, Fannie Welty. He founded a Dayton drugstore in 1876 and later manufactured Pretzinger's Catarrh Balm. He lived in the house until his death in 1909, and his widow stayed until about 1920. The design is attributed to his brother Albert, an architect who led the firm of Peters and Burns. Later the house served as the hospital administrator's residence and was vacant when nominated.","period_of_significance":"1889","architect_builder":"Probably Albert Pretzinger (stated as undoubtedly designed by Rudolph's brother, Albert)","architectural_style":"Queen Anne","criteria":[],"status_note":"Described as vacant at the time of nomination; formerly the residence of the Miami Valley Hospital Administrator.
