Florentine authorities laid the first stone of what would become the Duomo, commissioning architect Arnolfo di Cambio to design a cathedral grand enough to rival those of Florence's rival cities. The dome itself would not be completed until 1436, when Filippo Brunelleschi solved an engineering puzzle that had stumped architects for generations.

Born into a family of modest means in the Tuscan village of Caprese, Michelangelo would go on to sculpt the David and Pietà and paint the Sistine Chapel ceiling, reshaping Western art's standards for beauty and ambition for centuries.

After thirteen days of siege, some 1,800 Mexican troops under General Antonio López de Santa Anna breached the walls of the Alamo before dawn, overwhelming the garrison led by William Travis, James Bowie, and Davy Crockett. The defeat became a rallying cry -- 'Remember the Alamo' -- that fueled Texan independence weeks later at San Jacinto.

Scottish physicist James Clerk Maxwell demonstrated to London's Royal Institution a technique for producing color images by combining three separately filtered photographs -- a method that would underpin color photography, television, and digital displays for the next century and a half.

The Italian inventor secured British patent protection for his radio transmission system, a technology he had been refining since 1895 by sending signals over increasing distances across the English countryside. Within a decade, wireless telegraphy would transform naval warfare, maritime safety, and global communication.

At midnight, the Gold Coast officially became Ghana, ending British colonial rule and igniting a wave of decolonization across Africa. Kwame Nkrumah, who had led the independence movement and spent time in prison for it, declared the moment 'the greatest thing that has happened in Africa for hundreds of years.'

An East German man attempting to cross into West Berlin was shot dead by border guards, a grim reminder that the Cold War's deadliest frontier remained lethal even as reform winds were beginning to stir in the Eastern Bloc. Fewer than two years later, the Wall itself would fall.

Intel's Pentium processor began reaching computer makers in volume, offering roughly five times the performance of its 486 predecessor and cementing Intel's dominance of the PC market. Months later, the chip would become notorious for the 'FDIV bug,' a rare floating-point division error that cost Intel nearly half a billion dollars in replacement costs.
