Fort Myers's premier attraction pays homage to two of America's most ingenious inventors: Thomas A. Edison, who gave the world the stock ticker, the incandescent lamp, and the phonograph, among other inventions; and his friend and neighbor, automaker Henry Ford. Donated to the city by Edison's widow, his once 12-acre estate has been expanded into a remarkable 25 acres, with three homes, two caretaker cottages, a laboratory, botanical gardens, and a museum. The laboratory contains the same gadgets and gizmos as when Edison last stepped foot into it. Visitors can see many of his inventions, along with historic photographs and memorabilia, in the museum. Edison traveled south from New Jersey and devoted much of his time here to inventing things (there are 1,093 patents to his name), experimenting with rubber for friend and frequent visitor Harvey Firestone, and planting hundreds of plant species collected around the world. Next door to Edison's two identical homes is Ford's "Mangoes," the more modest seasonal home of Edison's fellow inventor. The property's oldest building, the Edison Caretaker's House, dates to 1860. Tours are guided or audio self-guided. One admission covers homes of both men; museum and laboratory-only tickets and botanical-garden tour tickets are also available.
