Biography
Ignatz Mizher was a member of the Communist Party from New York City. Ignatz Mizher served a sentence in Sing Sing and was later pardoned by Governor Smith.
1920s custody-date review: Release after Governor Smith's pardon is documented in February 1923; the exact day remains unresolved. This was a New York State criminal-anarchy case, not the generic federal Espionage/Sedition charge previously displayed. The study reports immediate immigration rearrest; this endpoint is state-prison release, not freedom from all custody. No immigration-release day is inferred.
