On this day in 1942, after sailing across the Atlantic Ocean, Italian explorer Christopher Columbus sights a Bahamian island, believing he has reached East Asia. His expedition went ashore the same day and claimed the land for Isabella and Ferdinand of Spain, who sponsored his attempt to find a western ocean route to China, India, and the fabled gold and spice islands of Asia. Columbus was born in Genoa, Italy, in 1451. Little is known of his early life, but he worked as a seaman and then a maritime entrepreneur. He became obsessed with the possibility of pioneering a western sea route to Cathay (China), India, and the gold and spice islands of Asia. At the time, Europeans knew no direct sea route to southern Asia, and the route via Egypt and the Red Sea was closed to Europeans by the Ottoman Empire, as were many land routes. Contrary to popular legend, educated Europeans of Columbus' day did believe that the world was round, as argued by St. Isidore in the seventh century. However, Columbus, and most others, underestimated the world's size, calculating that East Asia must lie approximately where North America sits on the globe (they did not yet know that the Pacific Ocean existed).
On this day in 1985, actor Rock Hudson, 59, becomes the first major U.S. celebrity to die of complications from AIDS. Hudson's death raised public awareness of the epidemic, which until that time had been ignored by many in the mainstream as a "gay plague." Hudson, born Leroy Harold Scherer Jr., on November 17, 1925, in Winnetka, Illinois, was a Hollywood heartthrob whose career in movies and TV spanned nearly three decades. With leading-man good looks, Hudson starred in numerous dramas and romantic comedies in the 1950s and 60s, including Magnificent Obsession, Giant and Pillow Talk. In the 1970s, he found success on the small screen with such series as McMillan and Wife. To protect his macho image, Hudson's off-screen life as a gay man was kept secret from the public.

The cornerstone is laid for a presidential residence in the newly designated capital city of Washington. In 1800, President John Adams became the first president to reside in the executive mansion, which soon became known as the "White House" because its white-gray Virginia freestone contrasted strikingly with the red brick of nearby buildings. The city of Washington was created to replace Philadelphia as the nation's capital because of its geographical position in the center of the existing new republic. The states of Maryland and Virginia ceded land around the Potomac River to form the District of Columbia, and work began on Washington in 1791. French architect Charles L'Enfant designed the area's radical layout, full of dozens of circles, crisscross avenues, and plentiful parks. In 1792, work began on the neoclassical White House building at 1600 Pennsylvania Avenue under the guidance of Irish American architect James Hoban, whose design was influenced by Leinster House in Dublin and by a building sketch in James Gibbs' Book of Architecture. President George Washington chose the site.
