The first is Jacques van Ypersele de Strihou who, as President of the Monetary Committee at the end of the 1970s, played a particularly important role in the design and establishment of the EMS (small wonder, if you realise that we shared a room as junior economists at the International Monetary Fund in Washington, D.C. in the mid-sixties).
The second is Jean-Jacques Rey who made two especially important contributions: first, as President of the Committee of Alternates of Central Bank Governors at the time the EMU Chapter of the Maastricht Treaty was negotiated and, second, as Chairman of the Monetary Policy Sub-committee of the EMI, which developed the operational framework for the implementation of the single monetary policy which has worked so well since January 1999.
