The landmark Emerson Tower, often referenced as the Bromo-Seltzer Tower, a 15-story skyscraper erected in 1911 in Baltimore, Maryland. It was designed by Joseph Evans Sperry for "Captain" Isaac E. Emerson, the creator of Bromo-Seltzer, a brand of antacid to relieve pain occurring together with heartburn, upset stomach, or acid indigestion. It was the tallest building in Baltimore from 1911 until 1923. The design was inspired by the Palazzo Vecchio in Florence, Italy. Photo by Carol Highsmith, 2018.
