Cecelia Kjerstine Larsen (born 1826)

In 1826, in the year that Cecelia Kjerstine Larsen was born, on March 10th, João VI, King of Portugal and the former Emperor of Brazil, died after a short illness. Six days earlier, the King had become ill after eating at the Jerónimos Monastery in Lisbon. An investigative autopsy in the late 1990's discovered that he had been killed by arsenic poisoning - having enough arsenic in his body to kill two people.

In 1832, on November 14th, Charles Carroll - the last surviving signer of the Declaration of Independence - died at his home in Maryland. He was 95 years old. He signed the Declaration as "Charles Carroll of Carrollton", distinguishing him from several other Charles Carroll's who were living in the area at the time.

In 1889, on March 31st, the Eiffel Tower was inaugurated. Because the elevators were not yet in operation, officials had to climb to the top of the tower - it took an hour. On May 15th, the Tower opened to the public - still without working elevators - but around 30,000 visitors still made the climb. The elevators went into operation on the 26th. The Tower wasn't considered aesthetically pleasing at the time but is now one of the most iconic structures in the world.

In 1937, on May 28th, the San Francisco Golden Gate Bridge opened to cars. Taking 5 years to build, the 4,200-foot-long suspension bridge was an engineering marvel of its time - 11 men died during construction. The "international orange" color was chosen because it resisted rust and fading. To the present, it is the symbol of the City that is known throughout the world.

In 1992, on February 1st, US President George Bush and President Boris Yeltsin of Russia jointly announced an end to the Cold War, proclaiming a new era of "friendship and partnership". At Camp David in Maryland, they reviewed ways to jointly reduce nuclear arms and support reforms in Russia but no agreement was reached at that meeting.
