Key takeaways

  • Most of this foundation's grants are modest: about 8 in 10 of its 202 grants to organisations fall between $2,500 and $50,000, and the median is $10,000, so a request in that region is a realistic size, though the largest grant reported was $105,000, which means that band is typical rather than a ceiling.
  • The filing states no geographic focus, and although Illinois accounts for the largest share of grant dollars, with New York, Massachusetts, the District of Columbia and California also receiving substantial shares, nothing in the filing sets those places as a limit on who may apply.
  • Education is the clearest theme from its grants, though the foundation does not state it as a focus.
  • Applications are accepted with no deadlines given, so submit in writing and state clearly the purpose of the contribution.
  • Giving is strongly repeat-led, with 95% of grant dollars going to organisations it had funded in earlier filings, so a new applicant should write a request that stands on its own rather than assume an existing relationship.
