Emerson Tower often referenced as Emerson Bromo-Seltzer Tower or the Bromo Tower is a 15-story, landmark 88 m (289 ft) clock tower erected in 1907–1911 at 21 South Eutaw Street, at the northeast corner of Eutaw and West Lombard Streets in downtown Baltimore, Maryland. It was the tallest building in the city from 1911 to 1923, until supplanted by the Citizens National Bank building (later First National Bank of Maryland, then occupied by MECU - Municipal Employees Credit Union) at the southeast corner of Light and Redwood (German) Streets. It was designed by local architect Joseph Evans Sperry (1854-1930) for Bromo-Seltzer (headache pain remedy) inventor Isaac Edward Emerson (1859-1931).
