Bernheim Brothers was founded in 1872. Bernheim Forest's later institutional account attributes the choice of the Harper name partly to Isaac's concern about prejudice against the German and Jewish associations of Bernheim. The brand-introduction date is disputed between the accounts compared; do not assign it definitively to 1872.
Sotheby's 2025 collector's guide dates first marketing as I. W. Harper to 1879, whereas Bernheim Forest's 2019 retrospective places introduction immediately after the January 1872 founding. Direct links to both accounts are in the page body.
September 14, 2026 correction: the prior verification established fidelity to one institutional account, not independent confirmation of the brand-launch date. Firm founding remains supported; naming motive remains attributed; brand chronology remains unresolved.
The source is a later institutional history, not a contemporaneous business record. Phrase the branding motive as Bernheim Forest’s account of Isaac’s reasoning and do not generalize it to all Jewish entrepreneurs.
This is a named, dated business and branding episode supported by the founder’s own institution. It demonstrates an explicit perception of ethnic and religious prejudice without requiring a generalized theory about all Jewish whiskey entrepreneurs.

Evidence decision
Retain as an attributed case study of identity and naming, not a settled brand-launch chronology. The earlier source-faithfulness verification did not independently establish the introduction date. See the Bernheim Forest account and contrasting Sotheby’s chronology. The 1872 firm founding remains supported; the brand-introduction clause requires further review.
