Key takeaways

  • The foundation's themes, drawn from its grants rather than stated by the foundation, are medical and scientific research and education, so a request fits best if it clearly serves one of those fields.
  • The filing shows $50,000 paid in annual giving and one recorded organisation grant, to a science centre, so a modest request is more realistic, though no grant range is stated.
  • The filing gives no application form, deadline, eligibility rules or application route, so ask the foundation how it takes requests before writing a full proposal.
  • No geographic focus is stated, so location alone should not rule you out, although the grants shown are mainly in Pennsylvania, which is worth knowing when you make contact.
  • The material does not say how competitive the foundation is or whether personal contacts matter, so approach it with a short, clear enquiry rather than assuming either way.
