Charles Thomson was an Irish-born patriot leader in Philadelphia during the American Revolution and the secretary of the Continental Congress (1774–1789) throughout its existence. As secretary, Thomson, a Founding Father of the United States, prepared the Journals of the Continental Congress, and his and John Hancock's names were the only two to appear on the first printing of the United States Declaration of Independence.

The first inauguration of George Washington as the first president of the United States was held on Thursday, April 30, 1789, on the balcony of Federal Hall in New York City, New York. The inauguration was held nearly two months after the beginning of the first four-year term of George Washington as president. Chancellor of New York Robert Livingston administered the presidential oath of office. With this inauguration, the executive branch of the United States government officially began operations under the new frame of government established by the 1787 Constitution. The inauguration of John Adams as vice president was on April 21, 1789, when he assumed his duties as presiding officer of the United States Senate; this also remains the only scheduled inauguration to take place on a day that was neither January nor March.
