Abstract
This article is based on the JSCE Society Award Lecture delivered at the ceremony of the Award presentation in recognition of the author's contribution to diffusion and development of corrosion science and engineering. The first part reviews the history of research and development in corrosion as affected by the change of society during the last one third of the century, in which the author served as a research engineer at the corrosion laboratory of a steel company. Then follow author's concepts, developed through experiences, of the significance of corrosion societies, “old boys network”, research work in industries, corrosion education, corrosion consultants, international cooperation, and intellectual property. Recent contribution to the diffusion of corrosion protection technology of buried utility piping, through which the author thinks he benefited society most, is described in some details.
