Biography
Edgecomb Pinchon was prosecuted under United States wartime statutes of the World War I era (chiefly the Espionage Act, the Sedition Act, or the Selective Service Act). Recorded offense: Violation of the Espionage Act. Sentence: 2 years. Sentenced August 31, 1918. Held at the McNeil Island. Later disposition: Paroled from McNeil Island. This case is documented in the 1921 U.S. Senate hearing "Amnesty and Pardon for Political Prisoners" (digitized by the Internet Archive).
1920s release-date review: Released on parole November 29, 1919. May 23, 1920 is the listed sentence expiration, not physical release.
Source: Amnesty and Pardon for Political Prisoners (1921), printed page 195, continuation of the Attorney General's January 20, 1921 list of persons paroled. The original table was visually checked, distinguishing release from sentence expiration and parole approval. Other custody endpoints remain under review.
1920s remaining-entry review: Kohn, page 124, gives an August 3, 1918 McNeil Island admission, while the Senate hearing places August 31 in its Offense column. The latter was imported as admission. August 1918 is retained at month precision pending the original register; August 1 is a storage placeholder, not an asserted day. The November 29, 1919 parole date is retained. No exact duration is inferred from the disputed day.
