The College of Music of Cincinnati was founded in 1878 by George Ward Nichols and funded with a lead donation from Reuben Springer. The famed conductor Theodore Thomas was immediately hired as the director, a fitting choice since Thomas had been informally involved in education all his life by bringing symphonic music to people throughout the United States. Initially classes were held in Dexter Hall, which was adjacent to the newly-constructed Music Hall.  

The 3rd courthouse was quickly built in 1873, a grand French Renaissance-style building, with a clock and bell tower rising 113 feet into the sky. It had a mansard roof, and was constructed of brick with iron cornices. Its size was a disadvantage when fire broke out in 1901; ladders and water could not reach the upper floors where the fire began. Documents were however safe in fireproof vaults built to protect them.

The Victoria, one of the oldest continually operated theaters on the continent, was opened to the public as the Turner Opera House on New Year's Day, 1866, at a cost of $225,000. Its initial offering was the James Sheridan Knowles drama "Virginius, starring Edwin Forrest – a play strongly associated with the famous actor. According to press clippings of that era, the theater was referred to as "the best [sic] theater west of Philadelphia". General admission was $1.

The site of the church that served as venue for Mark Twain and George W. Cable is now the location of the Duquesne Club. The church was sold to the Duquesne Club in 1886. The church bought a lot on the corner of Wylie Ave. and Congress in 1888.

Magnificent, majestic and massive, Detroit’s old Federal Building and Post Office was a towering palace of government that was more than three decades in the making, took seven years to build — and only 34 years to outgrow.

Wheeler Opera House, on the other hand, was a fabulous place (The Wheeler narrative is right after another hall called White’s). It became known all over the theatrical world for its modern arrangements, its magnificent decorations and its stage and lighting facilities. Jeff Wheeler, wealthy business man and sportsman, was proud of this monument to his family name.
