Leah Billings (born 1907)

In 1907, in the year that Leah Billings was born, radiometric dating, a recently discovered technology that could date rocks, found that the earth was 2.2 billion years old which was dramatically older than previously thought. Later refinements and advancements in science would date the age of the earth at over 4.5 billion years.

In 1912, the RMS Titanic sank in April. The RMS Titanic was a British built and run passenger liner that was billed as "unsinkable." On its maiden voyage from Southampton England to New York City, carrying about 2,224 passengers and crew - from the wealthiest people in the world to poor emigrants from Europe, the Titanic hit an iceberg. Five of her watertight compartments failed but she was designed to survive only 4 being flooded. She began to sink. There were only enough lifeboats for about half of the passengers so over 1,000 remained behind while "women and children first" were loaded. Over 1500 died, making it the largest maritime disaster in modern history.
