In 1937, Chang Tsu–suan graduated from the Department of Civil Engineering at Shanghai Chiao Tung University. After World War II, he came to Taiwan and was employed as an engineer. Later he joined governmental bureaucratic departments, during which he held several important positions, including Planner of UHDC (Urban Housing Development Committee), Director of Public Civil Engineering Bureau, and Vice Chief Secretary of Economic Development Committee of Executive Yuan. He participated in the development of public infrastructure, including urban planning and housing projects, the water supply system, zoning, and was part of the Division of Environmental Protection before the establishment of EPA. He had witnessed Taiwan’s development for almost half a century. This oral interview was conducted in 1998 while the author was a visiting scholar at Harvard. At that time, the author engaged in a project related to the establishment of National Parks in Taiwan, and she had planned to interview some major figures who could provide important information on this subject. As a faculty member of National Chiao Tung University, she found that Mr. Chang was not only an alumnus of Chiao Tung University, but he had participated in many environmental protection projects, hence the decision to interview Mr. Chang at his LA residence in 1998 to demonstrate part of Taiwan history contributed by the alumni of NCTU. During the two–day interview, the author found that Mr. Chang was particularly nice and humble. After the interview, the written papers of Chang’s oral statements, shown in a question–and–answer format, were sent to him. He himself reviewed and corrected those documents carefully. In this article, the author compiles all the oral references, and uses the first– person narrative to illustrate Mr. Chang’s life experience in Taiwan from 1947 till his retirement in 1985. Mr. Chang was a technocrat. He exemplified many crucial figures who played important roles in the early stages of the Taiwan’s development since the1940s. Through Mr. Chang’s oral statement, we are able to trace more contributors of his generation. He provided us valuable clues for further research in the future.
