Arumugam Vijiaratnam (24 August 1921 – 18 February 2016) was the only Singaporean who represented his country in four sports — hockey, cricket, football and rugby — doing so from 1946 to 1956.
A top civil servant, Vijiaratnam represented Singapore at the 1956 Melbourne Olympic Games in hockey, where he was instrumental in the 6-1 rout of the United States.
He played a key role in PSA's formation, helping to develop its containerisation programme, and rose to become its chief engineer.
He worked in PSA for 17 years and was one of two key men who were instrumental in reclamation works for Changi Airport, a feat that drew mention in Singapore's founding father, Lee Kuan Yew's Memoirs, From Third World to First: The Singapore Story.
He was also chairman of Tamil Murasu for ten years from 1995, and served on the Presidential Council for Minority Rights from 1994 to 2001.
