On the evening of June 11, 1816, local businessmen and socialites were invited to Rembrandt Peale’s Museum for a demonstration under the glow of artificial light.

At the corner of North Holliday Street and East Baltimore Street stands a monument to the first gas street lamp in the United States. Erected in 1997, the lamp is a replica of the early 19th century original. During a candlelit period in American history the forward-thinking Peale aimed to form a business around his gas light innovations, the exhibition targeting potential investors.
