Emeritus Professor Tetsuo Kanno was my superior, my mentor, exemplary role model to many young neurosurgeons, a visionary leader and loyal friend. His philosophy and teachings have left an indelible impression on many of us for years to come. Emeritus Professor Tetsuo Kanno’s accomplishments, legacy, and perseverance in the field of neurosurgery inspired many of us. His philosophy regarding life and neurosurgery have been guiding many of us in our daily practices.

He will always be in our hearts.” Our sympathy and prayers go out to his family members, and all those who were close to him.
