Biography
Isadore Berkowitz worked at the children's summer camp near Yucaipa, California. He was arrested with six women during the August 3, 1929 red-flag raid and taken to San Bernardino jail. The defendants obtained pretrial bail. The ACLU's April 1930 account places his death at the Workers' Cooperative Center in Los Angeles after the verdict and before sentencing, not in custody.
Yetta Stromberg’s first-person account in the November 13, 1929 issue describes the Yucaipa camp raid and San Bernardino prosecution, including the arrest of camp leaders and adults volunteering for cooking, washing and cleaning. It reports Sarah Cutler acquitted, while the others faced conspiracy proceedings; Stromberg additionally faced the red-flag count. The article places the trial’s conclusion on October 23 and reports $4,000 bail for the other defendants and $7,500 for Stromberg. The account prints an October 22 suicide date while collectively describing October 23 convictions, a chronological conflict left unresolved. Its attribution of illness to severe jail treatment does not establish death inside jail and does not replace the independently sourced account of death after bail at the Workers Cooperative Center. No prison sentence or death-in-custody date is inferred. Source: https://www.marxists.org/history/usa/pubs/dailyworker/1929/1929-nat/v06-n214-NAT-nov-13-1929-DW-Q.pdf#page=3
Further 1920s custody review: The ACLU April 1930 pamphlet names this defendant among the seven arrested in the August 3, 1929 Yucaipa raid and taken to San Bernardino jail. It records pretrial bail but no exact release day. Custody dates describe the initial jail detention, not admission to San Quentin; release is year-precision only. The same account places his death at the Workers Cooperative Center in Los Angeles, correcting the unsupported death-in-custody claim. No death-in-custody date is entered. Source: ACLU, The California Red Flag Case, April 1930, pages 3-6. This more precise account supersedes earlier provisional date notes; year-only release values are not January 1 release dates.
A contemporary death report outside the custody record
The October 25, 1929 Daily Worker prints a Los Angeles dispatch dated October 24 naming Isidore Berkowitz, the Yucaipa red-flag defendant recorded here as Isadore Berkowitz. It reports that he died by suicide after the verdict and before the other defendants were sentenced, using the relative wording Tuesday following. It reports his age as thirty and describes wartime gas injury and illness; those are attributed contemporary statements, not an independently established diagnosis or a birth date. The report adds contemporary death evidence but does not identify his place of death. The stronger ACLU account already recorded places his death at the Workers Cooperative Center rather than in custody. No death-in-custody field, exact death day, birth year or sentence is inferred from this report.

A reported October 10 verdict, before sentencing
The San Bernardino dispatch dated October 11 in the October 12, 1929 Daily Worker reports that six Yucaipa camp defendants were convicted on Thursday and individually names Isadore Berkowitz. That relative date places the reported verdict on October 10, 1929. The same report says sentencing was still conditional on denial of a new-trial motion and describes one-to-ten-year terms only as possible penalties. Its forecast is not a completed sentencing, prison admission or actual time served. The existing initial jail and pretrial-bail record remains intact, with no new custody endpoint or numerical total. This report predates the later death report and does not establish any death-in-custody event or exact death day.

An explicitly dated death report, with chronology limits
Yetta Stromberg’s signed camp account reports that Isadore Berkowitz died by suicide on Tuesday, October 22, 1929. It attributes his illness to wartime service and says severe treatment during earlier jail confinement aggravated his condition. These are contemporary allegations, not independently established medical causation or proof that he died in custody. The stronger ACLU account already preserved here places his death at the Workers Cooperative Center in Los Angeles after pretrial bail. The signed article also describes the case as concluding with conviction on October 23, although earlier contemporary reporting dates the verdict to October 10. Its internal sequence therefore needs qualification. The expressly printed October 22 death report is preserved as source evidence, not silently installed as an exact vital or custody endpoint. No sentence is assigned to Berkowitz from the sentences imposed on surviving defendants, and no death-in-custody field, demographic detail, birth date or numerical total is inferred.
