The station was activated in 1885. In 1916 the keeper's wife gave birth to a baby that summer at the station. According to the Alabama Lighthouse Association web site, the keeper brought a dairy cow to the station and corralled it on a section of the lower deck because his wife was unable to nurse the newborn baby. All had to be evacuated when the station survived but was damaged by a hurricane that year. The light was automated in 1935.
Middle Bay Light was deactivated in 1967. The lighthouse was placed on National Register of Historic Places on December 30, 1974.[1] In 1984 the lighthouse was stabilized by Middle Bay Light Centennial Commission in preparation for the centennial celebration. In 1996 the Coast Guard loaned the original Fresnel lens to the Ft. Morgan Museum for public display. In 2002 restoration efforts were begun to repair the lighthouse.
The Fresnel Lens was named for Augustin Jean Fresnel, a French physicist who, in 1828, demonstrated the wave theory of light and changed the entire world's lighthouse illumination to the Fresnel System. The Fresnel lens collected the light radiated at random from a small light source and directed the rays to the horizon.[2]
Whale oil was the first fuel used and the lighthouse tenders worked in shifts making sure that the lamps did not go out and smoke the lens. In later years kerosene was used and eventually they were converted to electricity.[2]
