, formerly Fullerton Building. Nathan worked in the building in the 1950s as the Seamen's Welfare Officer with the Marine Department. In recognition of this, during his state funeral procession his
cortège passed by the building. Nathan began his career in the
Singapore Civil Service as a medical social worker in 1955. He was appointed Seamen's Welfare Officer the following year. In 1962, he was seconded to the Labour Research Unit of the
National Trades Union Congress (NTUC), first as assistant director and later as director of the Labour Research Unit until January 1966. In February 1966, Nathan was transferred to the
Ministry of Foreign Affairs. He served as Assistant Secretary and rose to be Deputy Secretary before being appointed Deputy Secretary of the
Ministry of Home Affairs in January 1971. On 6 August of the same year, Nathan moved to the
Ministry of Defence where he was Director of the
Security and Intelligence Division (SID). In the
Laju incident on 31 January 1974, members of the terrorist
Japanese Red Army and the
Popular Front for the Liberation of Palestine bombed petroleum tanks on
Pulau Bukom off the coast of Singapore; Nathan was among a group of government officers who volunteered to be held hostage by the JRA and flown to Kuwait to secure the release of civilian hostages and ensure the terrorists' safe passage. For his bravery, in August 1974 he was awarded the
Pingat Jasa Gemilang (Meritorious Service Medal). In February 1979, Nathan returned to the Foreign Ministry and became its First Permanent Secretary until February 1982, when he left to become the Executive Chairman of the newspaper company the
Straits Times Press. The appointment was viewed dimly by journalists who felt that the Government was trying to limit
freedom of the press; they wore black armbands in protest. According to Nathan in a 2010 interview, " When they saw I was not doing what they expected me to do, they began to have confidence." At various times between 1982 and 1988, Nathan also held directorships of several other companies, including the
Singapore Mint, The Straits Times Press (London),
Singapore Press Holdings and
Marshall Cavendish. He held a directorship in the
Singapore International Media between September 1996 and August 1999. He was Chairman of
Mitsubishi Heavy Industries Singapore, a ship-repairing and engineering joint venture with the
Mitsubishi Group of Japan, from 1973 to 1986. From 1983 to April 1988, Nathan was Chairman of the
Hindu Endowments Board. He was a founding member of the
Singapore Indian Development Association (SINDA), and its term trustee until August 1999. In April 1988, Nathan was appointed Singapore's High Commissioner to Malaysia, and in July 1990 he became
Ambassador to the United States, serving until June 1996. On his return, Nathan was made an
Ambassador-at-Large and was concurrently Director of the
Institute of Defence and Strategic Studies at the
Nanyang Technological University. He resigned as ambassador and director of the institute on 17 August 1999 to become an independent candidate in the
1999 Singapore presidential election. ==Presidency (1999–2011)==
