In 1839, a group of gentlemen calling themselves the Alexandria Lyceum joined with the Alexandria Library Company to build a grand hall to provide a place for lectures, scientific experiments, and quiet reading. Eventually, the building itself became known as the Lyceum and, since that time, it has been a Civil War hospital, a private home, an office building, and the nation's first Bicentennial Center. In 1985, the Lyceum became Alexandria's History Museum, providing exhibitions, school programs, lectures and concerts, volunteer opportunities, and space for rental functions for the community.

A young physician named John Gorrie moved to Apalachicola in the early 1800s when it was a prominent port of trade, commerce, and shipping in Florida. Gorrie served as postmaster, city treasurer, town councilman, and bank director. Concern for his yellow fever patients motivated Gorrie to invent a method for cooling their rooms. He became a pioneer in the field of air conditioning and refrigeration by inventing a machine that made ice, and received the first U.S. Patent for mechanical refrigeration in 1851. A replica of his ice-making machine is on display at the museum, as well as exhibits chronicling the colorful history of Apalachicola, which played an important role in Florida's economic development.
