the University of Singapore In the 1970s, Nanyang University encountered problems in student enrolments as many students were attending English-language schools. Prime Minister of Singapore Lee Kuan Yew prompted the university to adopt English language within five years. Subsequently, in the same year in March, a joint campus scheme was introduced to allow students from Nanyang University to jointly study with students from the University of Singapore. In 1979, Lee invited British academic Frederick Dainton to present his views on the future of university education in Singapore. He suggested merging Nanyang University and the University of Singapore into the latter's campus at Kent Ridge. His proposal gained the support of the government and, in April 1980, the merger was confirmed. Nanyang University's 21st and last convocation was held on 16 August 1980. That same month, the National University of Singapore Act took effect, legally merging the University of Singapore and Nanyang University to form the National University of Singapore (NUS). Logo The three circles in the logo represent values long held to be important in Chinese tradition. They represent a trinity of values: people, progress and productivity. The linking shows the interdependence between the need for people to work together productively and achieve progress. This symbol can now be seen in the National University of Singapore's crest. The circle with the yellow star represents people, signifying the importance placed on human capital in Singapore. Relationship with Nanyang Technological University After Nanyang University was merged with the University of Singapore, the grounds formerly occupied by Nanyang University were occupied by a similarly named technical institute, the Nanyang Technological Institute (NTI), in 1981. In 1991, the NTI was upgraded to the status of a university as Singapore's second English-medium university and became the Nanyang Technological University (NTU). Chinese Heritage Centre In 1995, the former Nanyang University Library and Administration Building was reopened as the Chinese Heritage Centre, an autonomous research institute of Nanyang Technological University. It was the first and only university institute in the world that specializes in the study of the ethnic Chinese communities from different parts of the world. It currently served as a research centre, a library and a museum. Proposed renaming of Nanyang Technological University as Nanyang University The NTU administration announced in 2003 a decision to rename Nanyang Technological University as Nanyang University by 2005, justifying the move based on the university's introduction of non-technology-related schools
