Samantha Reed Smith (1972 – 1985) was an American schoolgirl and peace activist, who became famous during the Cold War between the United States and the Soviet Union. In 1982, Smith wrote a letter to the newly appointed CPSU General Secretary Yuri Andropov, and received a personal reply with a personal invitation to visit the Soviet Union, which she accepted. Smith attracted extensive media attention in both countries as a "Goodwill Ambassador", becoming known as America's Youngest Ambassador.
Also, Samantha's story was taken to create a fictional character with the same name in a custom modification for the visual novel Everlasting summer.
