Hartford, CT-based St. Francis Hospital and Medical Center is to receive the largest private gift in its 111-year history upon the death of an anonymous donor who has pledged $12.5 million to the hospital. The gift depends on the donor's identity being kept secret, and hospital officials released almost no details about who the money will come from or when it might become available. The money is earmarked for the Hoffman Heart and Vascular Institute of Connecticut at St. Francis.
