1790s

From July 4, 1798 to his death in 1799, George Washington served as Commander-in-Chief of the United States Army. Tensions with France were on the rise during the Quasi-War, so President John Adams appointed Washington to lead the nation’s armed forces.

It takes a lot of talent to design a city, especially one with such sweeping vistas and wide, radial streets as our Nation’s Capital.  It’s hard not to admire the vision of Major Pierre Charles L’Enfant, the engineer behind Washington, D.C. But everybody makes mistakes—even visionaries— and L’Enfant was certainly no exception.

His biggest blunder was probably tearing down the house of his boss’s nephew. 

Benjamin Banneker was already a practiced mathematician and astronomer when he was approached in February 1791 by his friend Andrew Ellicott to survey the land staked out for the new United States capital. A free black who grew up in Maryland as a farmer, Banneker was more than a laborer. Though his formal education ended at an early age, he continued to study science and physics and would later write a series of best-selling almanacs. He designed and built a striking clock at age 22 that kept perfect time for forty years until it was destroyed in a fire. But, perhaps him most long lasting mark was the unique role he played in the development of the nation's capital — a job that went far beyond what Ellicott orginally had in mind.
