History & Grounds. George Washington. On April 30, 1789, George Washington, standing on the balcony of Federal Hall on Wall Street in New York, took his oath of office as the first President of the United States.
They were able to be president because Article II of the Constitution established an exception that these men qualified for. Martin Van Buren is recognized as the first president born in the US, but this is questionable since the Revolution did not end until 1783. Arguably, John Tyler, born in 1790, was the first president born in the US.. Chester A Arthur was born near the US/Canada border, and although nobody knows for sure, a rumor states that he was born a Canadian, without his parents being aware of it.
