The only son of Malaysian statesman and MCA founder Tan Cheng Lock, Tan Siew Sin was born on 21 May 1916 in Malacca. He was of Baba heritage and did not speak Mandarin. He was educated at Malacca High School in Malacca and then at Raffles College in Singapore. Before then, he was also sent by his father to a Girls School, that is Suydaim Girls School which is now the Methodist High School. In 1935, he felt ill and was diagnosed as having tuberculosis. He fully recovered after an operation in Switzerland for treatment. Three years later, he moved on to his higher education in the field of law in England. He never completed his legal studies. Fearing an outbreak of war in Europe, in July 1939 Tun Tan Cheng Lock ordered him and his two sisters to leave London and return to Malacca. On Sept 1, 1939, Hitler invaded Poland, an event that marked the start of World War II. For this reason, He studied only one year of law. He returned from London to take over the family's plantation business in 1939.
Political career
Tan Siew Sin was elected a Member of Parliament for Malacca in 1955. He joined the Malaysian cabinet first as minister of trade and industry, and later became the finance minister in 1959. He then took over as president of the MCA in November 1961, and held on to both positions until 1974. Tan was appointed the Deputy Chairman of the Alliance in 1964. He led his party to victory in the 1964 General Election, winning 27 of the 33 parliamentary seats contested. Tan however came under criticism for not pushing for the recognition of Mandarin as an official language and the establishment of a Mandarin language university. In March 1968, Tan proposed setting up the Tunku Abdul Rahman College for Chinese youths who would otherwise be denied an opportunity to tertiary education. The college was formally set up on February 24, 1969. Under Tan's stewardship, the MCA also set up Koperasi Serbaguna Malaysia, an initiative of MCA Youth based on the cooperative principle. In the 1969 general election, MCA lost more than half its seats to the new, mainly Chinese Malaysian, opposition parties Democratic Action Party and Parti Gerakan Rakyat Malaysia. Tan considered taking the party out of the Alliance but decided against it. In order to regain Chinese support, Tan attempted to broaden the appeal of the party previously seen as a party of the taukeh, and invited professionals to join the party. Other initiatives included the Chinese Unity Movement and the Perak Task Force to help built support in New Villages in Perak. In 1973, Tan Siew Sin requested a position as Deputy Prime Minister in the cabinet reshuffle following the death of Tun Dr. Ismail, but this was refused by Tun Abdul Razak, which angered Tan. Tan retired from politics on 8 April 1974 after undergoing lung surgery. After his resignation he became a financial advisor to the government on economic issues.

He was also the chairman of United Malacca Rubber Estates, and sat on the boards of a number of companies, including Unitac, Siemens, Pacific Bank, Highlands & Lowlands, and Guardian Royal Exchange Assurance.
