Abstract: Professor Takeo Yokobori, the Founder President of ICF, passed away on 9 October 2017, at the age of 100. In this paper, his whole career and research achievements are summarized. He was the first who established multiscale mechanics harmonizing micro-material structures worldwide, such as dislocation groups and grain size, with the presence of cracks. He also proposed to call his approach “Fractology”, “Combined micro and macro fracture mechanics”, “Interdisciplinary approach” and “Holistic”. “Holistic” is translated to “The Whole Theory”. He considered it the most suitable philosophical term. In this paper, these concepts are also summarized.

Keywords: Statistical approach, fractology, combined micro and macro fracture mechanics, interdisciplinary approach, holistic
