George Washington's presidential residence was in Philadelphia, but he was active in creating a permanent place for future presidents to live and work. In 1790 he signed an Act of Congress declaring that the federal government would reside in a district "not exceeding ten miles square...on the river Potomac." Together with city planner Pierre L'Enfant, Washington chose the site for the new presidential residence, now 1600 Pennsylvania Avenue.
It has been 200 years since second president John Adams and his
wife Abigail Adams moved into the incomplete Executive Mansion in
the incomplete District of Columbia. Since then, forty more presidents
have lived in the building we now call the White House in the city
we know as Washington, D.C. Most were married, some were widowed,
and three were married while in office — although only Grover Cleveland
married at the White House. A steady stream of presidential children
and grandchildren have been born and raised there; a number have
been married there; and a few have even died in the place American
presidents call home.
