Dr. Paul Kleihues passed away March 17, 2022, at the age of 85 years.
Dr. Kleihues was a world-renowned neuropathologist in the field of brain tumor research. Starting his scientific and professional career at neuroscience and neuropathology institutions in Germany, he later served as director of the Institute of Neuropathology at the university hospital in Zurich, and subsequently as head of the International Agency for Research on Cancer (IARC), World Health Organization (WHO). He took responsibility for the WHO classification of human tumors, and was particularly interested in the integration of clinics, radiology, histology, and molecular genetics as fundamental basis for comprehensive and precise tumor typing. His personal professional and scientific activities, in tight cooperation with Dr. Hiroko Ohgaki, left a sustainable legacy in brain tumor classification.
Within the international neuropathology community, Dr. Kleihues was a highly appreciated and benevolent mentor, colleague, and friend.
