On March 31, 1889, the Eiffel Tower was dedicated in Paris in a
ceremony presided over by Gustave Eiffel, the tower’s designer,
and attended by French Prime Minister Pierre Tirard, a handful
of other dignitaries, and 200 construction workers.

On November 19, 1863, at the dedication of a military cemetery
at Gettysburg, Pennsylvania, during the American Civil War,
President Abraham Lincoln delivered one of the most memorable speeches in American history. In fewer than 275 words, Lincoln
brilliantly and movingly reminded a war-weary public why the
Union had to fight, and win, the Civil War. Lincoln’s address
lasted just two or three minutes.

Four score and seven years ago our fathers brought forth, on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

Now we are engaged in a great civil war, testing whether that nation,
or any nation so conceived and so dedicated, can long endure. We
are met on a great battle-field of that war. We have come to dedicate
a portion of that field, as a final resting place for those who here
gave their lives that that nation might live. It is altogether fitting
and proper that we should do this.

But, in a larger sense, we can not dedicate—we can not consecrate—
we can not hallow—this ground. The brave men, living and dead,
who struggled here, have consecrated it, far above our poor power
to add or detract. The world will little note, nor long remember what
we say here, but it can never forget what they did here. It is for us
the living, rather, to be dedicated here to the unfinished work which
they who fought here have thus far so nobly advanced. It is rather
for us to be here dedicated to the great task remaining before us—
that from these honored dead we take increased devotion to that
cause for which they gave the last full measure of devotion—that
we here highly resolve that these dead shall not have died in vain—
that this nation, under God, shall have a new birth of freedom—and
that government of the people, by the people, for the people, shall
not perish from the earth.

November 19, 1863.

On June 14, 1951, the U.S. Census Bureau dedicated UNIVAC, the
world’s first commercially produced electronic digital computer.
UNIVAC, which stood for Universal Automatic Computer, was
developed by J. Presper Eckert and John Mauchly, makers of
ENIAC, the first general-purpose electronic digital computer.

These giant computers, which used thousands of vacuum tubes
for computation, were the forerunners of today’s computers.

The Statue of Liberty, a gift of friendship from the people of  France
to the people of the U.S. was dedicated in New York Harbor by then
President Grover Cleveland.

On June 17, 1885, the dismantled Statue of Liberty, a gift of friendship from
the people of France to the people of America, arrives in New York Harbor
after being shipped across the Atlantic Ocean in 350 individual pieces
packed in more than 200 cases. The copper and iron statue, which was reassembled and dedicated the following year in a ceremony presided over
by U.S. President Grover Cleveland, became known around the world as an enduring symbol of freedom and democracy.

Intended to commemorate the American Revolution and a century of
friendship between the U.S. and France, the statue was designed by French sculptor Frederic-Auguste Bartholdi (who modeled it after his own mother),
with assistance from engineer Gustave Eiffel, who later developed the iconic
tower in Paris bearing his name. The statue was initially scheduled to be
finished by 1876, the 100th anniversary of America’s Declaration of
Independence; however, fundraising efforts, which included auctions, a
lottery and boxing matches, took longer than anticipated, both in Europe
and the U.S., where the statue’s pedestal was to be financed and constructed.

The statue alone cost the French an estimated $250,000 (more than $5.5 million
in today’s money).
