The 20th International Nathiagali Summer College (1995) was dedicated to Professor Abdus Salam, Nobel Laureate. A special session honored his extraordinary contributions to science and his efforts to promote research in the developing world. Distinguished scientists from Pakistan and abroad — many of them his close collaborators — paid tribute, while Dr. Riazuddin offered personal reflections on four decades of association with Salam.

Unable to attend in person, Professor Salam sent this message to the College:
“I send my very best wishes for the continuing success of the Nathiagali Summer College and feel honored that the 20th College is dedicated to me. I, however, regret that I will not be able to come personally to Nathiagali.” — Professor Abdus Salam

Following Professor Salam’s passing on 21 November 1996, the Salam Memorial Lecture became a permanent feature of INSC. Each year, a leading international scientist delivers this prestigious lecture, keeping alive Salam’s vision of advancing science through dialogue and cooperation.
