On October 19, 1781, British General Charles Cornwallis surrendered to General George Washington at Yorktown after 7,000+ British and German troops were taken as prisoners by American and French troops. The Battle of Yorktown was the last major battle of the American Revolution.

While no modern proof exists, legend has it that hours after the surrender, British troops marched out of Yorktown to the tune “The World Turned Upside Down.” The signing of the Treaty of Paris on September 3, 1783, brought an official end to the Revolutionary War. #OnThisDay

Join me for my new series, #FoundingFriday, where we explore history in the eyes of American statesmen. We’re starting today with a quote from Founding Father and second president, John Adams: “Liberty cannot be preserved without a general knowledge among the people.”

It sounds like a sci-fi video game, but this is a color analyzer at the National Archives! 🕹️ With this machine, preservation staff can view and set light cues for film negatives and adjust light levels for red, green, and blue at specific frames. #AmericanArchivesMonth

By using punched paper tape, staff can make density and color corrections. This helps in the creation of a new film copy that replicates how the film would have looked at the time it was made.

Shortly after assuming the role of First Lady, Betty Ford received a breast cancer diagnosis. On September 26, 1974, doctors discovered a tumor, leading to a mastectomy two days later. Breaking with social conventions of the time, Ford openly shared her diagnosis with the public.

While public openness about healthcare might not seem unusual today, Betty Ford's advocacy in the 1970s for regular screenings made an extraordinary impact and led to a widespread surge in mammograms known as the “Betty Ford blip.” #BreastCancerAwarenessMonth

The original caption to a photo of a soldier mid-obstacle course notes, “The Camp Hale course would be arduous enough anywhere, but when it is coupled with an altitude of almost 10,000 feet, the record of 10 3/4 minutes for the complete round is remarkable.”
