On 24 September, the ICTP will hold an official ceremony to dedicate the Juan José Giambiagi Lecture Room on the Lower Level of the Adriatico Guesthouse. Argentinean-born Giambiagi, who died in 1996, was one of the developing world's most honoured physicists and a leading figure for the promotion of scientific cooperation in Latin America. In 1962, he attended the Trieste Seminar that led to the creation of ICTP two years later. He was one of the Centre's first Associates and a frequent visitor to Trieste during the 1960s and early 1970s. In the 1980s, he was a member of the ICTP Scientific Council. The ceremony will include a presentation by the Centre's Director Miguel Virasoro, who is a former student of Giambiagi.
