April 26th in history:
On April 26th, 1986, a reactor at the Chernobyl nuclear power plant in the Soviet Union exploded during a test. Until an earthquake triggered an accident at a Japanese nuclear plant in 2011, the Chernobyl blast generally was considered the worst accident ever at a nuclear power plant.
A wartime bombing raid occurred on this date in 1937, when German planes attacked the Spanish town of Guernica, killing about one thousand people. The attack was immortalized in a mural by Pablo Picasso.
The German secret police force called the “Gestapo” was founded on April 26th, 1933. April 26th was also the birthday of Hitler aide Rudolf Hess (1894).
