Biography
Leon Callow was a Greek-born steelworker in Niles, Ohio who had lived in the United States for 39 years and supported nine children. Immigration officials ordered him deported for alleged past Communist Party membership. His federal appeal was remanded in 1956 so the district court could review the deportation order. The reviewed record establishes a civil removal proceeding but no arrest, booking, or confinement.
A Youngstown dispatch dated November 30, 1934 identifies Leon Callow as secretary of the Niles Unemployment Council, held by the U.S. Labor Department awaiting deportation. It says he had lived in the United States since 1915 and schedules a hearing for Monday, December 3; the scheduled hearing is not proof that it occurred or that he was deported.

Separate 1934 jail confinement and bail release
A Farrell, Pennsylvania dispatch dated December 2, 1934 identifies Leon Callow as secretary of the Niles local of the Trumbull Unemployed Workers Union. It reports that the International Labor Defense obtained bail and secured his release yesterday after ten days in jail on an allegation of conspiracy to overthrow the United States government. This supports December 1 as the derived release day and ten days of reported actual confinement. The article does not give the arrest or jail-admission day, and neither is calculated backward. Attorney Davis appeared before immigration officers seeking his deportation; this is not proof of completed removal. This episode is separate from the later deportation order and federal appeal described above. The ten days record this documented stay, not necessarily lifetime custody.
