Jens L Larsen (born 1907)

In 1907, in the year that Jens L Larsen was born, the Monongah coal mining disaster occurred on December 6th, happening at the Fairmont Coal Company’s No. 6 and No. 8 mines.. Over 361 miners were killed. Because there was no breathing apparatus at the time to help rescuers, recovery efforts were greatly hampered. It is considered the worst mining disaster in American history and led to government oversight in mining practices.

In 1914, in August, the Panama Canal opened to traffic. Begun by the French in the 1880's and abandoned, the United States undertook further construction in 1904. After 10 years, and the elimination of malaria carrying mosquitoes (which caused immense delays for the French and the Americans), the 48 mile long artificial waterway - a series of locks - created a shortcut for ships traveling between the Atlantic and Pacific Oceans.

In 1937, on May 6th, the German zeppelin the Hindenburg caught fire and blew up. The Hindenburg was a passenger ship traveling to Frankfurt Germany. It tried to dock in New Jersey, one of the stops, and something went wrong - it blew up. Thirty-six people were killed out of the 97 on board - 13 passengers, 22 crewmen, and one ground worker. The reasons for the explosion are still disputed.

In 1952, on February 6th, George VI of England died from a coronary thrombosis and complications due to lung cancer. His eldest daughter, age 25, immediately ascended the throne as Elizabeth II and her coronation was on June 2 1953.

In 1990, after 27 years in prison, Nelson Mandela, the leader of the movement to end South African apartheid was released on February 11th 1990.
