Benjamin Franklin's 200-Year Trusts Yield Millions for Boston and Philadelphia

other · 2026-09-07

In 1790, Benjamin Franklin launched a philanthropic initiative that ultimately benefited Boston and Philadelphia with significant financial resources from trusts that expanded over 200 years. He left £1,000 to each city, intended for loans to young apprentices. After a century, the trusts permitted the cities to allocate 75% of the funds for public projects, while the remaining 25% continued to accrue interest for another 100 years. By 1990, Boston's fund had reached around $4.5 million, and Philadelphia's was nearly $2 million. Boston utilized its trust to create the Franklin Union, whereas Philadelphia invested in The Franklin Institute. Franklin's vision was to foster enduring opportunities through civic projects, showcasing the effectiveness of long-term investments.
