Michi Nishiura Weglyn (November 29, 1926 – April 25, 1999) was an American author. In 1977, she wrote the book Years of Infamy: The Untold Story of America’s Concentration Camps, which fueled a movement leading to reparations for Japanese Americans interned during World War II, for which she was awarded the Anisfield-Wolf Book Award in the same year. She was also a vocal advocate for those denied redress under the Civil Liberties Act of 1988 and for the more than 2,200 Japanese Peruvians who were taken from their homes by the U.S. government and used in a hostage exchange program with Japan.
