Yasushi Nagao was the first non-American photographer to win the Pulitzer with this photograph snapped in Tokyo capturing the moment before seventeen-year-old Yamaguchi Otoya killed Socialist Party leader Asanuma Inajiro with a foot-long sword. Afterwards, while in detention, Yamaguchi wrote "Seven lives for my country. Ten thousand years for His Imperial Majesty, the Emperor!" on the wall and then hung himself. More background in this brief TIME Magazine article about the incident.
Nagao passed away a few months back on May 2, 2009.
