Evolution of the Theory of Slender Ships

Short Biography

Hajime Maruo, born in 1922, studied at the University of Tokyo, Department of Naval Architecture, and was graduated in 1945. This was followed by a post-graduate course, which he completed in 1947 with the degree of a Doctor of Engineering. Directly after his graduation, he worked as a lecturer at the Yokohama Technological Institute until April 1950. From 1951 to 1959, he taught as an associate professor at the Yokohama National University. In 1959, he became a full professor.

These activities were interjected by several stays abroad: Professor Maruo was a guest scientist at the Cavendish Laboratory of the University of Cambridge/England from 1957 to 1958 and worked as a guest professor at the Stevens Institute of Technology in Hoboken, USA, and at the University of California, Berkeley, in 1963. In 1973, he visited the Federal University of Rio de Janeiro for four months.

Hajime Maruo exhibits an very extensive scientific work, including publications in Germany. He worked on almost all areas of ship theory. However, his main interest was always the ship's resistance and related problems. Twice, 1948 and 1964, he received the award of the Society of Naval Architects of Japan and 1966 the award of the East Japan Maritime Administration. In 1980, he held the sixth David W. Taylor Lecture at the David Taylor Naval Ship Research and Development Center, Bethesda, USA.
