Biography
Leo Fisher edited the Croatian-language Chicago weekly Narodni Glasnik. In 1956 the federal government secured an order revoking his citizenship, relying in part on his failure to disclose an arrest connected with a Depression-era unemployment demonstration. The reviewed record establishes a civil denaturalization proceeding but does not establish a custodial interval for the earlier protest arrest.
The May 11 Milwaukee dispatch names Leo Fisher among the five convicted of riot and unlawful assembly after the March 6, 1930 unemployment demonstration. It does not give his individual term or physical custody endpoints. Daily Worker, May 12, 1930, page 1.

The September 8, 1930 Laisve, page 5, reproduces an International Labor Defense political-prisoner directory. Its row prints Leo Fisher, a term of 6 months, the year 1930 in the sentencing-year column, and confinement or correspondence location Station F, Box G, Milwaukee, Wisconsin. This is an attributed historical directory entry; printed years and nominal terms are not exact intake dates or measured time served, and mailing boxes do not independently identify a prison. The directory contains stale or conflicting chronology, so this row does not override independently established conviction, death or release facts.

The March 15, 1930 Daily Worker prints an arrest-scene photograph whose arrow explicitly identifies Leo Fischer, Communist Party organizer, among Milwaukee March 6 demonstrators being taken to jail. This corroborates actual custody in his already documented Milwaukee demonstration prosecution; the spelling Fischer is retained as the caption form. No precise physical discharge or total time is supplied. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1930/v06-n319-NY-mar-15-1930-DW-LOC.pdf#page=3
