In 1919, one hundred years after the founding of Singapore, two books were published to commemorate the occasion. These were One hundred years of Singapore edited by W. Makepeace et. al. and One hundred years’ history of the Chinese in Singapore edited by Sir Ong-siang Song. The 150th anniversary of the founding of Singapore falls in 1969. The present volume was planned in 1966 by the late Professor Lim Tay Boh (Vice-Chancellor of the University, 1965-67) as a contribution of the University of Singapore to mark the occasion. Aspects of the history, politics, geography, population and manpower and economic institutions and the social framework of Singapore are included in this volume as well as an up- to – date bibliography. We hope the collection of original essays presented here would prove to be of more than ephemeral interest to Singaporeans as well as to readers outside the Republic. But for his untimely death in 1967, the chief editor would have been Professor Lim Tay Boh. We would like to thank Mrs. Wang-Chen Hsui Chin, Secretary of the Publications Committee of the University, and Dr. Warwick Neville for their help in the production of this book.
