In 1999 the American Mathematical Society established the Epsilon Fund endowment to help support summer mathematics programs for mathematically talented high school students.  The name for the fund was chosen in remembrance of the late Paul Erdös, who was fond of calling children "epsilons."  The goal of the program is to aid and promote programs that support and nurture mathematically talented youth in the United States, and to make these opportunities available to the broad pool of all mathematically talented high school students living in the United States.
