Fannie assisted her husband in maintaining and servicing several lighthouses in the
Chesapeake Bay area:
York Spit Light (1904–1908),
Old Plantation Flats Light (1908–1912),
Cherrystone Bar Light (1912–1913),
Hog Island Light (1915–1922), and Turkey Point Light (1922–1947). All of the lighthouses the family was stationed at prior to 1922 were in Virginia.
Turkey Point Light Station Beginning in 1922, C. W. Salter served as the station keeper of Turkey Point Light, with Fannie once again assisting him with the day-to-day tasks. C. W. died suddenly on February 11, 1925, following an acute attack of
appendicitis. Upon his death, Fannie fully took over her husband's duties at the age of 43 and officially applied for his position shortly after. It was customary at the time for the family of the keeper to continue operating the station. The Salters had been preceded by three female keepers:
Elizabeth Lusby 1862, and
Rebecca Crouch 1895, who both took over following their husbands' deaths and served until their own deaths; Rebecca Crouch's daughter,
Georgiana Brumfield, wanting to follow in her footsteps, took over the duties from 1895 to 1919, retiring after spending 54 years on the homestead. Despite over 20 years of assisting with day-to-day operations of a lighthouse, she was initially denied the role by the
Civil Service, who cited her age as preventing her from being able to perform the necessary tasks. Salter petitioned
Senator Ovington Weller to appeal the decision. Weller then asked
President Calvin Coolidge, who overruled the Civil Service's decision and personally appointed her as official keeper at Turkey Point. Though U.S. presidents had appointed keepers in the past, Salter was the first female keeper with a presidential appointment to that point or since.
United States Lighthouse Service After her official appointment, Salter was issued a manual and learned how to use a
radiotelephone. She was on duty 24 hours a day, 7 days a week, and received a salary of $1,140 her first year in service, . Prior to being
retrofit for electricity, three brass oil lamps were cleaned and filled daily. At dusk, Fannie would fill one of the lamps with fuel, climb the tower, trim and light the wick, and place the lamp within the lens. She would recheck it about one hour later, and again at 10 pm before going to bed. Her bedroom in the keeper's quarters faced the tower, so she could ensure the light was functioning properly. If the light extinguished in the middle of the night, she would immediately wake up and have it reignited or replaced by one of the emergency lamps kept onsite. In 1928, the
United States Lighthouse Service (USLHS) authorized $25 per month () for a laborer to go to the station and manually wind the
fog bell striking mechanism. This charge was reduced to $15 per month in 1932 (). Once, during a particularly foggy day, the fog bell mechanism failed, and Salter had to manually strike the fog bell four times per minute for nearly an hour to help a steamer safely navigate the
Chesapeake and Delaware Canal. During this time, she missed the phone call from her son-in-law announcing the birth of her first granddaughter.
United States Coast Guard The U.S. Coast Guard absorbed the USLHS in July 1939, making all keepers, including Salter—the only woman employed by the USLHS at the time—civilian members of the Coast Guard. During
World War II, the Coast Guard had
shortwave radio systems installed in a number of lighthouses on the east coast to listen for
U-boat activity. Salter learned to maintain radio watch in addition to her other duties. They also had existing lighthouses electrified in place of the oil or
kerosene used in the past, with Turkey Point being upgraded in 1943. This upgrade meant that Salter could just flip a switch to power a 100-watt bulb that, in combination with the lens, could produce 680
candlepower of light, though a kerosene backup was maintained at all times in the event of a power outage. Still, there was work to be done, as each lens needed to be cleaned daily and polished at least once per week to be able to maintain the visual clearance needed for vessels to safely navigate the area. == Additional duties ==
