Rotary International, founded in 1905, is the oldest and largest service organisations in the world. Its motto is Service Above Self, and its objective (briefly) is to encourage and foster the ideal of service through fellowship, high ethical standards and the advancement of international understanding.
That does not stop significant ongoing local and international activity. The most awesome of these is Rotary’s commitment to eliminate the polio virus by immunising every child in the world for long enough that the virus has no host, and disappears. Hundreds of millions of dollars has been expended, recently boosted by $300M by the Bill and Melinda Gates Foundation.
