Pompei was destroyed and completely buried during a catastrophic eruption of the volcano Mount Vesuvius spanning two days on 24 August year 79. The volcano collapsed higher roof-lines and buried Pompeii under many meters of ash and pumice, and it was lost for nearly 1700 years before its accidental rediscovery in 1748.
Irena Sendler got permission to work in the Warsaw Ghetto as a plumber. She courageously smuggled babies in her tool box and carried larger children in her sack. She also trained her dog to bark when the Nazi soldiers were near, which muffled the sounds of the crying children. She helped save more than 2,500 children & was eventually caught & tortured. Sendler was nominated for the Nobel Peace Prize along with Al Gore, who won for his presentation on global warming...but she is a HERO!
