Peruvian Puzzle





In these photos we have identified F. Calogero, E. Ferrero-Costa, Joseph Rotblat and John Holdren.
 
These two photos are both dated 3rd of November 1991, which was
 the first day of the 3rd Workshop on Non-Military Dimensions of Global Security: Environment and Development in Latin America, held in Lima, Peru.
 
We have identified Calogero, Rotblat and Holdren in the top picture, but we can not be sure which of the two men second and third from the left is E. Ferrero-Costa. All of these four men attended this workshop. We have not identified the person sitting next to Ferrero-Costa. Do you know who he is?
