Not a celebrity, but a person that should be better known:
"And then, in the early 1980s, Mrs. Herzig Yoshinaga picked up a red bound volume sitting on the corner of an archivist’s desk. As she later told the Los Angeles Times, the book contained the original draft of a 1943 government report on internment, apparently the last such copy in existence. “I began thumbing through the report, and then, when I came upon an important section, I nearly hit the ceiling.”
Mrs. Herzig Yoshinaga, who was 93 when she died July 18 at a hospital in Torrance, Calif., had uncovered evidence suggesting America’s World War II internment policy had racist motives and was not a result of “military necessity,” as Pentagon officials claimed.
Her findings helped persuade Congress to pass the 1988 Civil Liberties Act, which granted $20,000 in reparations to each survivor of the camps and a formal apology from President Ronald Reagan."
