Who was the earliest founder of the Petersburg Club?

The earliest founder of the Petersburg Club, Prince Ben Harder of the Netherlands.

1954 At the end of May, organized by Dutch Prince Ben Harder, the world's economic, political and military elites gathered at the Petersburg Hotel in the Netherlands. Participants agreed to set up a secret group and name it after the hotel.

Since then, they have held a meeting in a luxury hotel somewhere in the world every year to secretly plan the future of human society. The qualifications of the participants are very strict, and they must be personally invited by the President of the Petersburg Club, accompanied by letters of recommendation from members of the Steering Committee for Conference Planning, the Advisory Group and the Honorary Secretary-General. No one can open the door to the Petersburg conference through money, power or other relationships. Rockefeller family, Rothschild family and Dutch royal family are the core of Petersburg Club.
