EARLY LIGHTS
Since man has traveled on the water, it has been necessary to ensure safe passage into harbors. The first light to assist these early mariners would have been a large fire placed on the hillside to direct them to the harbor.
Pharos of Alexandria, Egypt can be considered to be one of the first lighthouses in the world. This light was constructed over 2,300 years ago and stood over 400 feet high. The light would have been a large open fire with a giant mirror behind it to reflect the glow. The light was lit for over 1000 years and stood unlit for an additional 500 years. During the centuries, invaders and Mother Nature slowly destroyed the once great Pharos. An earthquake finally toppled this Wonder of the World; nothing of it remains today.
Lighthouses were first established in the United States along the coast where there were important commercial ports. Since there was no centralized government, many communities would establish their own lighthouse and maintain them. Localism played a large part in placement of the lighthouses; no one wanted to pay for a light in another colony or one that did not benefit the local merchants and people of the area. Until the area became prosperous it was not financially necessary to have a light.
As the country grew, more and more lights were placed, and it became difficult for the ship captains too positively locate the correct port. To correct this problem the lighthouses were painted in varying color schemes and the lights themselves were given different patterns of flashing known as "characteristics". Guidebooks to the lights were created so that the captains would be able to distinguish the different lights and find the way into the harbors. With the continuing growth of the country it was necessary to build lights along the major waterways into the interior of the country, these lights placed were secondary to the coastal lights.
FORT WASHINGTON LIGHT
The Potomac River
was the major waterway into the newly established Capital City, 1800. The river
has many water hazards, which could severely damage a ship. The U.S. Government
purchased 6- acres of property from the Digges family to build a fortification
to defend the new city. Fort Warburton was established on Digges Point in 1809.
The channel for large ships that need to have a large amount for water to stay
afloat must come within 50 yards of the shoreline. During the War of 1812 this
fort was destroyed, Fort Washington was completed in 1824. As the military reservation
grew and river traffic to Washington, DC increased the need for a lighthouse
to became evident. The Secretary of Treasury, James Guthrie requested in 1856
that a light be placed on Digges Point. Since this area belonged to the War
Department it was necessary to receive permission from the Secretary of War,
Jefferson Davis.
Davis
agreed to allow a light to be placed with conditions that "the light
shall be placed upon the wharf and not within any of the fortifications; and
the light keeper shall be subordinate to the military command of the post and
public ground in all that relate to police and discipline. If the care of the
light can be placed with the Ordnance Sergeant, it will prevent interference
with his present charge of other public property." With this permission
the Lighthouse Board appropriated $500 for a light. This first light was an
18.5-foot iron post, which was placed November 7, 1857. Following the recommendations
of the Secretary of War the care of the light was placed under the command of
the Ordnance Sergeant, Joseph Cameron. Cameron who joined the Army in 1806 served
for 66 years, 37 of these years were at Fort Washington where he died in 1872.
Cameron remained light keeper until 1869.
The 1857 light pole
remained
until the 1870’s when growth of the wharf caused obstruction to the light. A
small 16-foot tower was built closer to the water's edge to replace to light
pole. This was considered the first "real" lighthouse and a sixth
order Fresnel lens was placed in the tower. In 1822, Augustin
Fresnel
of France introduced a glass lens that revolutionized the lighting of lighthouses.
For many years, early American lighthouses burned whale oil as an illuminant
in metal lamps and later lamps with mirror-like reflectors. The Fresnel Lens
resembled a giant, old-fashioned beehive, inside of which was a single lamp.
The lens' thick glass prisms bent the lamp's light to the center of the lens,
which greatly magnified the light into a powerful beam that could be seen form
many miles at night. Fresnel made his lenses in six different sizes or "orders".
The 1st, 2nd, and 3rd order lenses were usually installed in seacoast lighthouses
to warn ships that they were approaching land. The 4th, 5th, and 6th order lenses
were used in harbor and sound lighthouses. A first order lens was the largest,
being over ten feet high, and the smallest, a sixth order lens was only 18 inches
high and 12 inches in diameter.
Fog has
always been a concern
for
lighthouses, because it limits the distance a light can be seen from the water;
therefore, early light keepers would fire cannon to warn the boats away from
the shore. As time went on, bells were placed in the light towers and would
ring when it was foggy. The fog on the Potomac River is no different. When it
rolled in, it was
impossible
to see the light. In 1881, several captains and pilots petitioned the Lighthouse
Board for a fog bell to be placed at Fort Washington. This was approved and
a tower was built in 1882 to house the fog bell. The fog bell tower would rise
to a height of 32 feet, with a base of 16 feet and narrowing to 4 feet at the
top. The bell that was placed rang once every 15 seconds.
As Fort Washington
continued to grow as a military reservation, the light tower was once again
obstructed from view. Funds were requested from the Lighthouse Board to build
a new lighthouse to replace the 1870 light that was in need of repair. These
requests were never acted upon, in order to keep the light working on the Potomac
River, the Fresnel lens was removed from the light and placed into the 1882
fog bell tower. Beginning in 1898, requests were made that the light/fog bell
tower and keepers quarters to be tor
n
down to accommodate military necessities. The old light tower was in poor condition
and it was recommended
that a new tower be built. In 1901, the Lighthouse Board had the 1870 light
tower torn down instead of repairing or rebuilding a new one. The sixth order
Fresnel lens was put out and replaced
by a small automatic light. This new light had the characteristic of a fixed
white until 1920 when it was changed to a fixed red light. This decision was
made because there were too many white lights
on the Potomac River.
When
Fort Washington was transferred to the Department of the Interior in 1946, the
Light Station remained under the Control of the United States Coast Guard. During
1948, the Light Station consisted of the light/fog bell tower, a seven-room
medium frame dwelling, a timber dock and a frame boat house. One person was
assigned to take care of the light as well as 21 other lights and 5 lighted
buoys along the Potomac River, approximately 40 miles round trip. In 1950, it
was recommended that all property and dwellings be turned over to the National
Park Service with the exception of the tower that would remain under the ownership
and care of the Coast Guard.
The
year 1954, marked the end of the light keepers at Fort Washington, the light
went to an unmanned automatic flashing red light. During the years that followed
the wharf and all buildings associated with the lighthouse were removed. The
light/fog bell tower is all that remains of a once active light station. Sometime
during the late 1970’s the fog bell mechanism broke, ending the bell ringing
at Fort Washington. Today, Light 80, is still operated by the United States
Coast Guard, a triangle red marker locates it during the daylight hours while
at night the light still flashes red at six second intervals with a visibility
of 6 miles.
