John Fennessy, ICTP head of administration since June 1998, has retired from the UN system after 26 years of service to assume the position of head of administration and finance, Organization for Security and Cooperation in Europe (OSCE), in Skoplje, Macedonia. During his tenure, the ICTP Main Building and guesthouses underwent major refurbishing, including an unprecedented expansion of the Centre's lecture halls and an upgrading of the cafeterias. Fennessy also spearheaded the drive to hold Trieste's first UN Day at the Centre last fall.
