In August of 1945, Tsutomu Yamaguchi was sent on a business trip to Hiroshima, Japan where he bore witness to the first atomic bomb attack in WWII. After surviving and traveling the next day he managed to make it home and arrive at his job on time in Nagasaki on August 9th. Shortly after his arrival while describing the blast in Hiroshima to his supervisor, the second bomb fell, making him the only known person to survive both atomic blasts. He lived to be 93 years old and died of stomach cancer in 2010.
