P.T. Barnum played a significant role in the history of public aquariums in the United States by recognizing the commercial potential of exhibiting living aquatic animals to the public.1

In 1856, he opened the first display aquarium at his American Museum in New York City. Operating as a private enterprise, this exhibit was part of his broader career as a showman, where he utilized his signature style of sensational publicity and exhibition to attract large audiences to his various attractions. By integrating living aquatic displays into his museum, Barnum helped introduce the concept of the public aquarium to American audiences, predating the widespread establishment of such institutions that would follow in the 20th century.123
