Exactly three years after the end of World War I, the Tomb
of the Unknown Soldier is dedicated at Arlington Cemetery
in Virginia during an Armistice Day ceremony presided over
by President Warren G. Harding.

Two days before, an unknown American soldier, who had
fallen somewhere on a World War I battlefield, arrived at
the nation’s capital from a military cemetery in France.

As the soldier was lowered to his final resting place, a two-
inch layer of soil brought from France was placed below his
coffin so that he might rest forever atop the earth on which
he died.

On October 4, 1927, sculpting began on the face of Mount
Rushmore in the Black Hills National Forest of South Dakota.

It would take another 12 years for the granite images of four
of America’s most revered presidents—George Washington,
Thomas Jefferson, Abraham Lincoln and Theodore Roosevelt
to be completed.

The monument was the brainchild of a South Dakota historian
named Doane Robinson, who was looking for a way to attract
more tourists to his state.

The POW/MIA flag was first recognized on August 10, 1990.

On May 30, 1922, President Warren G. Harding became he first
president to have his voice transmitted by radio while addressing
a crowd at the dedication of the Lincoln Memorial.

The broadcast heralded a revolutionary shift in how presidents addressed the American public. It was not until three years later, however, that a president, Calvin Coolidge, would deliver a radio-
specific address.

In 1920, radio station KDKA in Pittsburgh, PA announced that
Harding was the official winner of that year’s presidential election. 

In 1923, he recorded a speech on an early “phonograph” that
recorded and played back sound on wax discs. Harding was also
the first president to own a radio and was the first to have one
installed in the White House.
