Kilmer.","why_significant":"The nomination argues the house is an outstanding example of monumental late nineteenth century residential architecture in Binghamton. It is also tied to the Kilmer family, whose patent medicine business and civic roles shaped the city's economy and cultural life. It is one of the largest and most unusual houses in the Riverside neighborhood.","narrative":"Built in 1898 at 9 Riverside Drive in Binghamton, this large stone mansion was designed by local architect C. Edward Vosbury for Jonas M. Kilmer, who ran the family patent medicine business with his son Willis Sharpe Kilmer. The house rises two and one-half stories with an irregular form, gables, turrets, a round three-story tower, glazed ceramic tile gable ends and a high hipped roof. Inside, a central hall organizes the rooms, which have wood paneling, exposed beams, Renaissance-inspired plasterwork and a former third-floor ballroom. The Kilmer family kept the house until 1950, when Temple Concord bought it. A synagogue was added in 1964 and joined to the house by a connector using the old porte-cochere. The house is recognized as an outstanding example of monumental late nineteenth century residential architecture, and it recalls a family prominent in Binghamton's business, banking and newspaper life. Neighboring Vosbury-designed mansions have been demolished.","period_of_significance":"1898","architect_builder":"Charles Edward Vosbury, architect","architectural_style":"Late 19th and 20th century revivals (eclectic Victorian era design combining Queen Anne elements with masonry construction)","criteria":["A"],"status_note":"The house was bought by Temple Concord in 1950 and is now used for religious and school purposes.
