Memories of a friend and colleague - Takashi Sugimura

Takashi Sugimura, M.D., Honorary President of the National Cancer Center in Tokyo, and former President of The Japan Academy, is regarded by many as a pre-eminent contributor to the field of environmental genotoxicology. His pioneering spirit led to many key discoveries over a long and distinguished scientific career, including the first preclinical models for gastric cancer, identification of novel mutagens from cooked food, and the development of fundamental concepts in environmental chemical carcinogenesis. With his passing on September 6, 2020, many will reflect on the loss of an astute and engaging Scientific Giant, who with warmth and good humor maintained lasting friendships both at home and abroad, beyond his many important scientific contributions.
