Episode Details

On April 29, 1429, seventeen-year-old Joan of Arc arrived at the Siege of Orléans, a moment that shifted the momentum of the Hundred Years' War and eventually led to the coronation of Charles VII. This episode of Deep Dive explores how a teenaged girl from Domrémy convinced a skeptical court and inspired a demoralized army to achieve a pivotal military victory against English domination. Beyond the medieval battlefield, we recognize three cultural giants born on this day: jazz pioneer Duke Ellington, who led his orchestra for over half a century; legendary comedian Jerry Seinfeld, who co-created one of the most influential sitcoms in television history; and eight-time Grand Slam champion Andre Agassi, whose power and charisma redefined professional tennis. We also delve into the surprising engineering history of the zipper, which was granted a critical patent to Gideon Sundback on this day in 1913 after decades of development.
