Figures are aggregated from The Stanley S Langendorf Foundation's IRS Form 990-PF electronic filings (2 filings on file, most recent tax year 2025). Totals reflect grants the foundation reported as paid, and can lag the current year because foundations file annually and often on extension. Source: IRS 990-PF filing on ProPublica.
