From my peplum group on Facebook I have been given the information that he was born on November 18th 1935 in Saint-Malo, France, but without knowing where this information originated it should be treated as unconfirmed.
As far as is known he is still living at the time of writing (he was certainly alive as recently as 2008, confirmed by images).
