Venetian merchant Marco Polo, traveling with his father and uncle, completed an arduous journey across Central Asia to reach the Mongol emperor Kublai Khan's court, likely around this time in 1275. Polo would spend roughly seventeen years in Khan's service, and his later account of Yuan China introduced Europe to the wealth and sophistication of the Mongol Empire.

Clara Barton, a battlefield nurse during the Civil War, founded the American Red Cross after years advocating for the U.S. to join the Geneva Convention.

Flying the single-engine Spirit of St. Louis, Charles Lindbergh landed at Le Bourget airfield outside Paris to a crowd of over 150,000 cheering onlookers. He had departed Roosevelt Field in New York the previous morning, navigating largely by dead reckoning across open ocean and fog banks with no radio and little sleep. The flight won him the $25,000 Orteig Prize and instant global fame.

Amelia Earhart set down her Lockheed Vega in a farmer's field near Derry after nearly 15 hours battling ice, fog, and a leaking fuel tank on her flight from Newfoundland. She startled a local farmhand who asked if she had flown far; she replied, 'From America.' The flight, five years after Lindbergh's, cemented her status as aviation's most famous woman.
