John Bromfield’s initial bequest of $25,000 in 1846 has grown to more than $6.5 million. His generosity and foresight enabled the Library to maintain its distinction as one of the country's leading research institutions. Those who follow in John’s footsteps by making a planned gift to the Athenæum are invited to join the John Bromfield Society. Bromfield Society members are recognized in the Annual Report and are invited to a special Athenæum event once a year.

Planned gifts can include bequest intentions, real estate gifts, or gifts of life insurance or retirement plans.
