John F. Kennedy

Less than two months into his presidency, JFK signed Executive Order 10924, formally creating the Peace Corps as an agency within the U.S. State Department. By the end of 1961, 750 inaugural Peace Corps volunteers had served in 13 countries.

Twenty-three days before his assassination, JFK signed his final bill: the Community Mental Health Act, funding local mental health care.
