Book excerpt: Remembering S R Nathan: A Mentor for All Seasons is a collection of essays commemorating the life of Singapore's sixth President, the late Mr S R Nathan. The book aims to give greater insights into the wide-ranging roles he had in his various contributions to Singapore. It reviews his leadership and influence, his distinguished civil service career, and his commitment to social service. The organisation of the sections in the book reflects the extensive footprints Mr Nathan has left in many different sectors: foreign service; security and intelligence; community building and social welfare; labour and trade unions; media; and research and academia. This book also contains views on his remarkable career from foreign observers. Other contributors include public servants, policymakers, and scholars who have worked with him, learned from him, and who were inspired by his lifelong dedication to Singapore. Told through the voices of these people, Remembering S R Nathan: A Mentor for All Seasons gives an informative, and yet, personal account of Mr Nathan as a leader and mentor.
