About May 12
May 12 carries a quiet but remarkable tradition of firsts. In 1926, the Norwegian-built airship Norge soared above the North Pole, accomplishing what no vessel had done before. Fifteen years later in Berlin, Konrad Zuse presented the Z3, the inaugural working programmable, fully automatic computer—a milestone that quietly planted the seed of every digital device that followed. And in 1949, the Soviet Union lifted its blockade of Berlin, ending a crisis that had pushed the Cold War to the edge.
The day also resonates with educational heritage. In 1364, Jagiellonian University opened its doors in Kraków, becoming Poland's oldest institution of higher learning. Nearly two centuries later, in 1551, Lima saw the founding of the National University of San Marcos—still the oldest university in the Americas. Meanwhile, on today's observance calendar, International Nurses Day honors the birth of Florence Nightingale in 1820, celebrating the woman whose statistical mind and tireless reforms revolutionized modern nursing.
From royal coronations to bold expeditions, May 12 has witnessed empires shift and boundaries break. Richard I of England wed Berengaria of Navarre on Cyprus in 1191, crowning her queen that very same day. In 1797, a young Napoleon Bonaparte seized Venice, reshaping the Italian map. And in 2002, former President Jimmy Carter arrived in Havana for a historic visit with Fidel Castro—the first U.S. president, sitting or former, to travel to Cuba since the revolution.
